4 High, mid or low vacuum we master them all Capturing at source The most efficient way to capture air pollution in industry is as close to the source as possible. One avoids extracting large air volumes and above all the pollutant is not spread around in the room. This is what we refer to as capturing at source. Contaminants may be in the form of solid waste, dust, fume, mist and gas, produced, for example, in a metalworking process such as welding or grinding or in a handling process involving foodstuffs or chemicals. The extraction of exhaust fumes from car and truck engines is another typical example of solving problems at source. Optimal solutions Capture at source technology can be divided in two main categories: High vacuum = high speed extraction - low air volume Low vacuum = low speed extraction - high air volume Sometimes we also refer to mid vacuum. This technique is applied in applications with light dust and shavings where the extraction capacity can be adjusted in order to save energy and reduce noise. Nederman masters the whole spectra of vacuum technologies from high to low vacuum. Therefore, we always can offer the most practical and cost-effective solution from our extensive range of products and systems. See also product guides on pages 8-11 High vacuum High vacuum, i.e.high speed extraction is done very close to the source or directly on the source. Typical applications are floor and machine cleaning, extraction from high speed tools such as grinders, cutters, sanders and suction from welding guns. The high vacuum technology allows solutions with flexibility over the whole working area combined with low air volumes. Low vacuum Low vacuum, i.e low speed extraction, allows capturing the pollutants at a greater distance due to the higher air flow. Low speed capturing is recommended for extraction of fumes, dust exhaust and other airborne particles. The extraction is carried out with extraction arms, exhaust nozzles, enclosures and canopies over machines. High vacuum Low vacuum Type of contaminant Airborne particles and solid waste Airborne particles Vacuum kpa Airflow m 3 /h per extraction point up to 3000 Particle velocity m/s up to 25 2

5 Applications with explosive risks Risk Evaluation Form The Nederman Risk Assessment Report (published on filled in by the customer, qualifies and quantifies the pertinent aspects of the production process, including, for example, the type and composition of the dust, the air flow requirements and the extraction system. We then recommend suitable equipment for the described application and guarantee its functionality with respect to the information supplied. Each project is individually documented in detail for future reference. The consequences of fires or explosions can be extensive and include rupture of afilter systems and recirculation of contaminated air with subsequent health risks and damage to plant. Although it is impossible to completely eliminate the risk of creating explosive mixtures, it is possible to reduce the risk of ignition and the effects of an explosion. Where dust is concerned, assessment is based on the risk of combustible dust being present in the atmosphere, classified on a scale from continuous presence of explosive concentrations to unlikely presence with limited short term risks. A similar scale is used for assessing the risks involved when dealing with gases. Directives for explosive applications Within the EU, harmonized regulations have been in force since 1994, whereby employers are required to assess the risk of creating an explosive atmosphere in their production environments. Two other directives became mandatory in 2003 concerning explosive applications: European Directive 99/92/EC/ATEX 137 This directive states that it is the responsibility of the user/ employer, to assess and classify the working environment. Thus, the risk of working in a potentially explosive atmosphere is the first criterion that has to be examined when choosing an extraction arm, filter or fan for any operation or process. The Nederman Risk Assessement Report will be the basis for the choice of products for which we, as manufacturer and supplier, will be responsible with regard to product compliance. What is a dust explosion? An explosion is the rapid combustion of a mixture of dust and gas usually air. Dust concentrations have to be high enough to feed the combustion chain reaction.the speed of the resulting shock wave is less than 340 m/s. If the mixture is highly turbulent there could be a more violent explosion and the shock wave could reach 2,000 m/s, causing extensive damage. Potential ignition sources are also important to assess. For example, sparks from grinding or welding, electrical sparks, and glowing material from the work process. Examples of different types of explosive dust Baking flour, soup powder, spices, Organic dust in the food industry: flavouring Synthetic organic dust: Powder paint, plastic, grinding dust European Directive 94/9/EC/ATEX 100a The European Directive 94/9/EC applies to the equipment manufacturers and harmonizes the technical and legal standards to which equipment for use in potentially explosive atmospheres is manufactured. Nederman offers a range of Ex approved and marked products which are manufactured according to these requirements. Metal dust: Pharmaceutical dust: Aluminium, magnesium, titanium, and chromium A great number of powders 3

10 Nederman Extraction Solutions in Industrial Applications The table gives a brief overview of the Nederman products and systems. When designing a system it is important to take into account all the parameters i.e. type of contaminants, number of extraction points, work space area, air flow, air volumes and temperature of the extracted air at the inlet. Other parameters to consider are required filtration effici ency, possible recirculation of air and potential safety hazards etc. On the following pages you find detailed information.

14 Capture at source Low vacuum solutions Generally speaking, low vacuum products and systems are used for extraction purposes where the air is contaminated with small, light and low velocity particles that can be regarded, for design purposes, as acting like a gas. Welding fume and baking flour dust are good examples of potentially hazardous substances that are best dealt with at source. This means that: their removal uses high volumes of air, m³/h they are extracted via large diameter ducting at relatively low speeds, around m/s the pressure drops that have to be overcome are low, normally in the region of 1 3 kpa. Typical applications for low vacuum solutions engineering processes such as welding grinding and oil mist recycling food and pharmaceutical processes involving the handling of powders or chemicals. In these last instances there is often a latent explosion risk and specially adapted products are available for dealing with such situations. Bench top applications Bench top extraction of fumes, vapours and light dust is often used in small-scale or light industrial applications such as soldering and gluing or working with solvents. Schools, laboratories, health clinics and medical research institutions are some of the workplaces that can benefit from these solutions. Detailed product information about bench top extraction can be found in the Nederman Product Catalogue. NEDQuote NEDQuote is a powerful design and calculation program, and a unique tool in which different set-up scenarios for arms, filters and fans can be investigated. See Nederman Customer Support for further details. Dimension the ducting Air volume m³/h Duct diameter mm Fume Air velocity m/s Duct diameter mm Dust Air velocity m/s up to A low vacuum installation with fan, filter and arms 12

15 How to dimension In the dimensioning example it is assumed that only 50% of the extractors are in operation simultaneously. The calculation then provides the approximate maximum airflow and vacuum requirements so that a suitable fan can be chosen. If a careful analysis of frequency of use is carried out, and dampers and inverter equipment are installed, it will often be possible to further reduce the size of the fan. Dimensioning the ducting The following simplified dimensioning procedure can be used for any extraction system: 1. Draw a simple sketch Mark the proposed locations of the extractors, the filter (if any) and the fan. Note the length of the ducting and how many 90 bends are required. In this example it has been assumed that there are m of ducting and 5 bends. 4. Calculate the required vacuum Determine the required vacuum by carrying out the following steps: a) Read off the pressure drops for the 4 m and 2 m NEX HDs working at 1200 m³/h. The model requiring the greatest vacuum will provide the dimensioning value. In this case, it is 340 Pa for the 4 m arm. Note! Only one arm shall be calculated. b) Add 5 Pa for every metre of duct, measured from the arm furthest away from the fan. 20 metre of duct in this example. c) Add a further 15 Pa for every 90 bend. 5 bends in this example. d) Add 1200 Pa for the filter, FilterMax F, single module. (With a filter area of 60 m² and an operational load of 40 m³/m²h the filter unit can handle an airflow of 2400 m³/h). See page 25 for suitable filter cartridge. The required vacuum is: (20 x 5) + (5 x 15) = 1715 Pa 2. Choose extraction arms Two 4 m and two 2 m NEX HD arms have been chosen. 3. Calculate the total airflow required The arms will be used for heavy welding, requiring 1200 m³/h per arm. This means a potential maximum airflow of 4800 m³/h if in operation simultaneously. In practice, however, it is most probable that only 2 arms will be in operation at the same time, which means that the design airflow rate will only be 2400 m³/h (1200 m³/h m³/h = 2400 m³/h, 50% use). A= Filter B= Fan 13

16 5. Choose the fan N 29 The connection from the extractor arm to the main duct should always be at least 160 mm in diameter. For more precise dimensioning of ducting, please contact your supplier. Note! When using the NEDQuote design and calculation program, different installation set-ups can be quickly investigated to determine an optimum solution. NCF 30/25 NCF 30/15 Always check that there is a sufficient incoming air supply to the workplace. In a common ducting system, with one fan serving several extractors, there is a risk of temporary fluctuations in suction capacity and pressure drop, but these problems are easily overcome by using dampers and frequency controlled fan. x= airflow y= static pressure How to dimension High Vacuum Systems see page 40. The required fan capacity is 2400 m³/h at 1715 Pa. A suitable fan is the NCF 30/25. In this example, the following duct dimensions are required: Airflow, m³/h From arm 1 to arm From arm 2 to arm From arm 3 to arm From arm 4 to filter From filter to fan From fan to outlet Duct, mm 14

17 Low Vacuum Extraction Arms The Nederman range of extraction arms covers a wide variety of applications for use in both explosive and nonexplosive environments. The different models meet the requirements of the relevant European Directives, such as Directive 98/37/EC concerning safety of machinery and Directive 94/9/EC, commonly known as the ATEX 100a Directive, concerning the use of equipment and protective systems in potentially explosive atmospheres. Before an extraction arm is chosen, it is the responsibility of the user/employer, according to European Directive 99/92/EC, or ATEX 137, to assess and classify the working environment. The resulting classification will be the basis for the choice of arm for which Nederman, as manufacturer and supplier, will be responsible with regard to product compliance. All Nederman arms are highly flexible, and simple to position, extend and retract. Different attachments are available for wall, ceiling or extension bracket mounting as well as a number of accessories, including hoods and dampers to improve efficiency.

24 Low Vacuum Filters The first step towards effective and safe removal of fumes, gases and dust from the workplace is choosing the most suitable extraction arm. The next step is to consider how the contaminants are to be removed from the extracted air so that it can be returned to the atmosphere or recycled without negative impact on the environment or workplace. These situations are often governed by stringent regulations with significant economic penalties if they are not observed. Filter systems must therefore be chosen to fulfil a number of basic requirements and the first main division of types is with regard to their use in explosive or non-explosive environments. The production environment must be assessed and classified according to current directives. The filters in this handbook are for stationary installation; there is also an extensive choice of mobile filter units, see the Nederman Product catalogue for further details. The Nederman FilterMax System This is a modular system of filter units designed to deal with all types of fume and dust resulting from mechanical working or handling of a wide range of materials. If additional workplaces are added to the extraction system, increasing airflow requirements, then new modular sections can be easily added. There is also a compact stand-alone unit, C 25, for low volume applications where space is limited. Dimensioning example Light welding requires handling a load of 50 m³/m²h. In a FilterMax DF with a single module the filter area is 72 m², which means that it can filter 3600 m³/h (50 m³/m²h x 72 m²). This is equivalent to the volumes of extracted air from 3 or 4 welding stations in simultaneous operation. It could be advantageous to consider a twin module set-up to ensure sufficient capacity and longer cartridge life. Note: The welding shop in the example might have a total of 15 welding stations, but with a usage frequency of 15%, the filter suggested will be sufficient. When designing filter systems it is always important to take into account additional parameters such as the temperature of the extracted air at the inlet, the required filtration efficiency, possible recirculation of air and potential safety hazards. Nederman FilterMax C25 For further information see the Nederman Product Catalogue. Nederman FilterMax F 30, 60 and 90 The filter handles the air polution from metal industries as well as non explosive dust from other industries. Integrated pre-seperator for coarse particles, sparks, etc. A wide range of cartridges for different purposes are available. Protection class IP54. In- and outdoor installation. Nederman FilterMax DF 40, 80 and 120 The filter handles the air polution from metal industries as well as non explosive dust from other industries. A wide range of cartridges for different purposes are available. Protection class IP54. In- and outdoor installation. Nederman FilterMax SFC FilterMax SFC gives increased safety against release of dangerous dust into the atmosphere. If the filtered air is recirculated a FilterMax SFC is vital to maintain a safe work environment. In combination with a pressure switch the FilterMax SFC can work as an emmission alarm as well as a safety filter. FilterMax SFC can be used as a heavy duty general filter cabinet in applications such as vehicle exhaust or fine dust. One FilterMax SFC module filters the air from one FilterMax F or FilterMax DF module. The maximum capacity is 4000 m³/h, at heavy loads this is reduced down to 2000 m³/h. For general filtration of dust or fume the capacity is 2000 m³/h. The FilterMax SFC cabinet can be equiped with straight inlets or a combinations of 90 and straight inlets. Nederman FilterMax DX 3000, 6000 and 9000 Designed for extraction of dry powder or dust with explosion risk applications or if explosion protection is demanded accordingly to the ATEX directive. Nederman s Dustline serie includes FilterMax DX and extraction arms and fans for explosive environments. Food, medical or chemical industries are likely users for this application.

These are chosen depending on the source of the contaminant and the required degree of filtration. The type and intensity of the operations will determine the life of the cartridge, typically around 6000 hours of continual use. Filter cartridges are chosen depending on specific filtration requirements defined by particle characteristics and required efficiency. Cartridges are cleaned using powerful, pulsed shockwaves. The DF, F and DX units are fitted with automatic control systems for cleaning during and after operation. All FilterMax filters are available for indoor and outdoor use (except the C25 indoor use only).

30 Oil Mist Filters Dealing with oil mist Oil mist is the aerosol that is often formed when oil is used as a coolant/lubricant during the machining of metal components. The mist comprises drops of oil, or oil and water emulsion. It is well known than prolonged and repeated exposure to oil products can be detrimental to health, which means that good ventilation must be ensured under all working conditions. Precipitation of oil mist on machinery, equipment and the workplace floor can be both detrimental and dangerous. Mineral oil-based metalworking fluids are known as neat cutting oils or straight oils. They normally contain a number of undisclosed additives that can affect the viscosity of the oil. Emulsions normally contain 5 10% watersoluble oil and 90 95% water. The Nederman range of oil mist filters NOM is designed for use in conjunction with machining work where emulsions are used as the coolant/lubricant. They can also be used in the metalworking press industry. Contact Nederman for further information. If straight oil is used the load must be moderate and limited to mg/m³ in the aerosol phase. The viscosity of the coolant and degree of contamination will also affect the efficiency of the filter system and its working life.

The smoke comprises submicron-size particles or partially combusted oil. This often occurs, for example, in hot bar press applications, and when gear cutting and die-casting aluminium. Contact Nederman for further information. Recommended capacity Investigate the routines to get full information regarding number of machines operating at the same time, size of machines,working hours a day (shift) and the cycle time. Calculate the airflow capacity from a typical situation For frequently openings of the door (manually handling of tools, item, etc) an increased airflow is required in the opening period due to increased open areas. For automatic machines with normally closed doors it is necessary to delay opening of the door. It is of primary importance to generate well balanced under-pressure so the oil-mist is removed and the bigger droplets of oil or emulsion stay back in the machine for recycling. Recommended air velocity 0.2 m/s through closed machines Example: Scrap openings and other openings and gaps in a closed machine might give an area like 1.0 m². 1.0 m 2 x 0.2 m/s x 3600sek = 800 m 3 /h A totally open machine needs a column hood. Recommendation for emulsions Pay attention to the viscosity (viscosity >200mm²/s, balance the airflow carefully) Make sure the filter never is running with clean air through the filters. Never leave the dirty filters unused for a longer period time. If filter is left unused or running with clean air, water will dry out from the emulsion which will crystallize on the filter surface,and might block the filter. (Nedermans filters can be cleaned with lukewarm water and dishing detergent like Fairy, if necessary) Recommendations for straight oil Applications with straight oil and high workload need a well balanced down time period for at least 2 x30 min/24 hours for draining the filters. The filter units are simple to install, even in limited spaces. All models are machine-mountable. Compact or standalone models are available. In processes where oil smoke frequently occurs, the NOM Oil Mist Filter can be used to handle the oil mist deriving from swarf and chips created, for example, by CNC machines. Oil smoke occurs when straight oil, used as lubricant/ coolant,heats up and a white or bluish-white smoke is given 28

31 Nederman NOM 4 The NOM 4 is designed for single CNC machines with limited oil mist, enclosed cabinet. Nederman NOM 11, NOM 18 and NOM 28 These filters are designed for applications with need for larger airflow capacities. In all metal fabrication with oil mist troubles, these filters will fit into a central system, connected to each machine. All units are equipped with pressure gauge for control of filters as well as a indication for need of cleaning (self draining).

32 Dimensions NOM 4 NOM 28 NOM 11 NOM 18 *) Measure depending on extension legs position *) Measure depending on extension legs position *) Measure depending on extension legs position Recommended installation During operation with closed door the airflow can be reduced, i.e. with a motorized damper. Before the end of the cycle the airflow can be increased by opening of the damper. The reduced airflow will reduce the amount of extracted oil mist and oil vapors. The damper control could be connected to a dedicated output from the machine control system or from a signal from the coolant pump system. The position of the outlet in the CNC machine should be protected from direct oil injections, as from the chuck. Install adjustable dampers for each machine. 30

33 Low Vacuum Fans The first design criterion is whether or not the environment can be subject to explosions. The production environment must be assessed and classified according to current directives. Nederman fans are designed for use in all types of industrial processes and ventilation systems, and are constructed for both indoor and outdoor use. The choice of fan depends on the pressure drops and flow requirements of the system in question. In some cases it might be more economical to choose a number of smaller fans instead of one central fan for space reasons or when loading conditions are difficult to specify. The size of the fan will be determined by the vacuum required to overcome the pressure drops in the extraction arms, filters and ducting and by the airflows required to maintain the correct transportation speeds of the contaminated air. To reduce power costs and increase efficiency, the use of fan starters, dampers and fan inverters is recommended. These will minimize the required airflows in the system and optimize the fan speed at different work loads. Sound absorbers are available for use with NCF range fans.

37 Airflow control Fans designed to handle full-time use of all extraction arms in an installation risk being over-dimensioned. This is because the frequency of use at each workplace is generally significantly lower than a theoretical maximum design load. To deal with these situations there are Nederman solutions that offer considerable savings in power and maintenance costs. Noise levels will also be reduced if airflows can be kept to a minimum. Nederman Fan Starter/Fan Contactor The cost-effectiveness of the extraction system can be improved if the fan only operates when work is being carried out. A fan contactor can be activated via a sensor clamp attached to the earth cable of welding equipment or a switch in the hood. Installing a fan starter: reduces power costs minimizes the volume of heated air extracted air from the premises allows a stop delay of up to 5 minutes to ensure extraction of remaining dust and fumes A conventional direct or Y/D- starter for NCF fans.

41 Capture at source High vacuum solutions A Nederman High Vacuum System offers multi functionality. This means that our installations can be designed for any application: Welding fume extraction Grinding/sanding/cutting dust extraction Cleaning Metal chip extraction Dimensioning To dimension a high vacuum installation, the total airflow needed (m³/h) must be established. This is much depending on the application and also on the use of automatic valves. To make it easier to determine which High Vacuum Unit to choose, the names of the products are related to their capacity. For example, a VAC provides an approximate airflow of 2500 m³/h at a working vacuum of -20 kpa. Airflow Installations without automatic valves must be dimensioned for the full use of all outlets! The capacity of the vacuum unit and the pipe system must be large enough for all outlets connected at the same time. Installations with automatic valves can be reduced in size. The vacuum unit and also the pipe system can be made smaller. Due to the fact that the valves open and close automatically as soon as a tool is, respectively, switched on or off, the installation can be sized for the average amount of users at the same time. Even if this is possible also when using manual flap valves, it is now known that the valves will close as soon as the operation is discontinued, thus the vacuum level can be guaranteed. The average amount of users for which the installation is designed should be agreed upon together with the customer. It is known from experience that the amount of users on an average is about 30 % of the total amount. On larger installations, the required airflow can therefore be reduced to 30% of the flow for full use of all outlets. There are different simultaneous factors for dfferent applications as shown in the calculation sheets. Vacuum Normally the vacuum is not calculated if the basis requirements below are met. If the installation for example contains much longer piping system please ask Nederman for advise. The procedures of how to make the right choice can best be illustrated by going through examples on the following page. In assistance to this, the sheets and diagrams will be helpful. Basics All values given for vacuum and flow as well as all other design parameters are based on some general basic rules. Total length from vacuum unit to the furthest away located inlet, Max 200 m. Main pipe diameter 100 mm. Max flow/main pipe m³/h (600 is the norm, 800 can be accepted intermittent) When required the main pipe system is build up by several 100 mm pipes. Dropper pipes Ø 63 mm. Max length of a dropper pipe 15 m. Only one inlet (> 150 m³/h)/dropper. NOTE! A high vacuum system needs a minimum pressure drop in the system to work properly as e.g. filter cleaning is based on a pressure difference in the system and the outside atmosphere. Using short hoses or big diameters in pipes and hoses, the pressure drop can be considerably lower the normal and therefore result in poor filter cleaning. When a system is used by few operators (compared to calculated simultaneous factor), the amount of air taken in at a specific inlet can me much higher than what is mentioned in the calculation sheets, or the velocity in the pipes might me to low to transport the material. 39

44 Dust explosions On 1 July 2003, two ATEX directives became mandatory: The ATEX Directive 94/9/EC, which applies to equipment manufacturers and harmonizes the technical and legal standards to which equipment for use in potentially explosive atmospheres is manufactured. The ATEX Directive 99/92/EC, which applies to endusers and requires a complete, documented analysis to be conducted on sites that may have a potentially explosive atmosphere and that only ATEX certified electrical, mechanical and safety related systems are installed. The Directive 99/92/EC states that it is the responsibility of the user/employer to assess and classify the working environment as to whether there is a risk of explosive atmospheres, taking into account at least the following: the likelihood that explosive atmospheres will occur and their persistence. the likelihood that ignition sources, including electrostatic discharges, will be present and become active and effective. the installations, substances used, processes and their possible interactions. the scale of the anticipated effects. In short, the first step is to determine whether the risk is due to gas or dust, the second step is to determine the classification zone. Classification zones for GAS Zone 0: An area where an explosive atmosphere is continually present or present for long periods of time, for example inside liquid fuel tanks. Zone 1: An area where an explosive atmosphere is present in normal operation but not continually, for example refuelling areas. Zone 2: An area where an explosive atmosphere is not likely to occur in normal operation and if it does occur it will exist only for a short time, for example storage areas of solvent in sealed drums. Classification zones for DUST Zone 20: Place in which an explosive atmosphere in the form of a cloud of combustible dust in air is present continuously, or for long periods of time or frequently. Zone 22: Place in which an explosive atmosphere in the form of a cloud of combustible dust in air is not likely to occur in normal operation but if it does occur, will persist for a short period only. In addition, the kst-value (dust explosion constant) and temperature range must be established in order to complete the specification of the products. Risk assessment Due to the fact that most organic materials, synthetic materials and metals can explode, a great deal of attention has been given to dust explosions in recent years. The risk of a dust explosion requires the presence of three components: oxygen, a dust cloud with the necessary particle size and migration characteristics, and a source of ignition. Oxygen is always present to some extent. Dust a high concentration (> 40 g/m3) of most substances is required to create a risk of a dust explosion (a simple test, though not applicable to all materials: if you cannot see a 25 W light bulb from a distance of 2 m, then there is a risk of a dust explosion). If this is the case, the dust density is far higher than the hygienic limit, so it is most unlikely that such a zone will exist inside a working environment. This concentration level will only be found inside a filter, container or similar space and the Directives will not be applicable unless there is electrical equipment inside. Ignition a flame, heat or more likely static electricity can start an explosion. A Nederman extraction system comprises conductive parts, steel pipes, conductive hose couplers, valves in conductive plastic etc, to avoid sparks from static electricity. Nederman FlexFilter solutions are available for use in Zones 21 and 22. The Nederman Norclean line includes products for use in Zones 00, 01, 02 and 20. Risk assessments often show that there might be a high enough concentration of dust inside the filter to cause an explosion. In these cases, most filters can be supplied with an explosion relief panel. This must be vented or placed outdoors and surrounded by a clearly designated safety zone. Zone 21: Place in which an explosive atmosphere in the form of a cloud of combustible dust in air is likely to occur in normal operation occasionally. 42

45 General design rules a) Risk zone approx. 15 m (depending on material). b) Unit securely ancored to the floor. c) Max. 1 m length, min. 2 mm pipe thickness. No diameter reduction. d) Well displayed warning signs. 43

55 High Vacuum Valves Automatic vacuum valves A wide range of automatic vacuum valves is the key to an efficient high vacuum system. The valve controls the capacity of the system and makes it easier to decide which unit you ll need. All this will save operating costs. The range of valves can be used for welding, grinding, floor cleaning or other applications. TAV 50 can be fitted with a micro switch which is part of an AS-set (option). The switch controls the vacuum plant to make it stop when all valves are closed and to make it start again as soon as a valve is opened. A pilot signal cable and a suitable motor starter are required to execute this function. Nederman TAV 50 The TAV valve opens and closes by means of a pneumatic cylinder. The cylinder can be controlled by a flow sensing valve for pneumatic tools, or by a solenoid valve for electrical tools, welding and other applications. The TAV valve is suitable where automatic vacuum valves are required. The TAV valve can be used for welding, grinding, floorcleaning or other applications.

91 Systems for emergency vehicles Nederman MagnaSystem solutions The Nederman MagnaSystem is a series of lightweight and easy to install exhaust extraction systems designed specifically for emergency vehicles and featuring 100% exhaust capture. The system can also be used in bus and coach garages if vehicles with similar exhaust positions and anchor plates always return to the same parking bays. It comprises two basic variants, MagnaRail and MagnaTrack. The MagnaSystem uses an electro-magnet to attach the exhaust hose and nozzle to the vehicle. When activated, the electro-magnet attaches to an anchor plate on the vehicle, holding the nozzle firmly on to the tail pipe. When leaving the parking bay : a radio link (optional) ensures that the extraction fan starts when the engine is turned on the hose unit follows the vehicle as it exits at a pre-set disconnection point, the electro-magnet is deactivated the nozzle is then instantly released, preventing stress on the tail pipe and risk of injuries due to recoil on release. An oversized nozzle permits an ambient air mix in the air stream, immediately reducing the emission temperature by up to 50 % at the point of capture. This prolongs component life and prevents burning hazards. Airflow recommendation: ambulances 600 m³/h, fire trucks/buses m³/h.a The fan can be set to run after disconnection to ensure complete extraction of any remaining exhaust fumes. The anchor plate is mounted at a convenient height on the vehicle body enabling nozzle attachment while standing upright. The anchor plate is the nozzle attaching point on the vehicle. It is mounted at a convenient height on the vehicle body enabling you to attach the nozzle while standing up right.

97 Nederman MagnaStack MagnaStack is a 100 percent automatic exhaust extraction system for vertical stacks, based on the same technique as MagnaTrack. The extraction unit, however, is a hood enclosure, which automatically connects with the vertical exhaust stack as the vehicle is backed in to the parking bay. Guide arms position the laterally adjustable hood to the stack. The stack is attached to the hood with an electromagnet. As the vehicle moves towards the exit, the horizontal hose and extraction hood follow smoothly along the guide track. At the doorway the electric power is automatically switched off, instantly releasing the exhaust stack from the hood. Capacity: 1 vehicle per system Normal speed exit: up to 15 km/h - 10 mph Exhaust pipes: vertical stacks Pressure drop MagnaStack Magna Stack is an exhaust extraction system designed for vehicles with stacks, i.e. vertical exhaust pipes.
