Revised: 11.9.214 Sales, delivery and payment terms 1. Applicability: These sales, delivery and payment terms (hereinafter the Terms ) apply to all offers, orders and deliveries supplied by JKF Industri A/S, CVR no. 17824 (hereinafter JKF Industri ) to any customer (hereinafter the Buyer ) (hereinafter collectively referred to as the Parties ), unless expressly agreed otherwise. JKF Industri cannot be bound by terms applied by the Buyer, including purchasing terms, even if JKF Industri has not objected to such terms. 2. Offers All offers are made subject to the goods being unsold. If JKF Industri makes an offer that does not stipulate a specific time for acceptance, the offer will expire if not accepted by the Buyer within 3 days of the date of the offer. 3. Prices All prices are stated in DKK excluding VAT, customs duties, taxes, transport costs and all other costs which are the responsibility of the Buyer arising from the contractual EXW clause (see below). Prices are stated in EUR exclusive of the aforementioned costs for Buyers located in countries, which are members of the European Economic and Monetary Union (the Euro). 4. Sales and delivery terms Payment terms are current month + 2 days net calculated from the date of invoice unless otherwise agreed in writing. If payment is made after the due date and the delay is no fault of JKF Industri, JKF Industri is entitled to charge interest on the sum outstanding as from the due date, at a rate equivalent to 1. % per month or part thereof. The Buyer is not entitled to offset any counterclaims against JKF Industri unless expressly agreed in writing by JKF Industri, and does not have the right to withhold any of the purchase sums by reason of counterclaims of any kind.. Retention of title For Buyers in the United Kingdom: The goods shall remain the property (i.e. title) of JKF Industri until: (ii) the full price for them is paid; and (ii) all sums for any other goods or services then properly due and payable from the Buyer are paid to JKF Industri. JKF Industri may at any time attribute any money received by it from the Buyer in any order as JKF Industri may decide. Until such payment, the Buyer shall hold the goods on a fiduciary basis as the bailee or depository of JKF Industri, and shall not dispose of them. However, subject to JKF Industri s prior written consent, the Buyer may on the Buyer s own account sell the goods to any customers but shall not do so after any step is taken or made for any composition or arrangement with creditors generally, liquidation, winding-up, dissolution, administration, receivership or bankruptcy of the Buyer. If any such step occurs, or JKF Industri reasonably expects that such a step is soon to occur, or any payment due to JKF Industri from the Buyer becomes overdue, JKF Industri may by written notice terminate the Buyer s right (if any) to sell the goods and JKF Industri may then recover such goods and for that purpose enter any premises, subject to the Buyer s continued liability to pay the price for the goods. If the item has been sold with a view to later being built into or joined to other objects, the item sold is not covered by the right of retention once such installation or joining has taken place. JKF Industri reserves the right within the limitations of mandatory laws to retention of title to the item sold until payment for the entire purchase sum, plus any costs incurred, has been made to JKF Industri. If the item has been sold with a view to later being built into or joined to other objects, the item sold is not covered by the right of retention once such installation or joining has taken place. For Buyers outside the United Kingdom: JKF Industri reserves the right within the limitations of mandatory laws to retention of title to the item sold until payment for the entire purchase sum, plus any costs incurred, has been made to JKF Industri. If the item has been sold with a view to later being built into or joined to other objects, the item sold is not covered by the right of retention once such installation or joining has taken place. 6. Delivery Unless otherwise agreed in writing between the Parties, the delivery dates stated are EXW JKF Industri s address, with a proviso for possible schedule overruns (see below). The use of EXW means that the goods are deemed to have been delivered and the order fulfilled from the moment they are made available for collection by the Buyer from JKF Industri s address. Unless otherwise agreed in writing between the Parties, JKF Industri is authorised to order transport on the usual terms on behalf of the Buyer. The Buyer, will continue to bear the risk for arranging transport, and if it cannot be arranged, the goods will be deemed to be delivered from the time at which JKF Industri states the purchaser can collect them. Regardless of which of the Parties has ordered it, shipping will always be at the risk and expense of the Buyer. Transport insurance (if any) will be the responsibility of the Buyer. The delivery clause (EXW) agreed between the Parties is to be interpreted in accordance with the INCOTERMS current at the time of signing the agreement (currently INCOTERMS 21). The delivery date is set by JKF Industri according to the best judgement, and if this cannot be kept to, the Buyer will be informed accordingly, with when, as far as possible, delivery can be expected to take place. Any delay does not give the Buyer the right to cancel the sale and/or claim any form of financial compensation from JKF Industri. 7. Packaging Packaging may only be returned by prior written agreement. Return of packaging is at the Buyer s own expense and risk. The Buyer s packaging will be credited after reception and approval by JKF Industri. 8. Product information and confidentiality All illustrations, technical drawings and brochures issued by JKF Industri before or after the contract have been entered into remain the property of JKF Industri and must be returned to JKF Industri on request. Such materials must be treated with strict confidentiality and cannot be used, copied or passed on without written agreement, or abused in any other manner. The Buyer undertakes to generally observe confidentiality concerning all aspects of JKF Industri known to the Buyer as a result of the information the Parties have exchanged in the course of their dealings. Breach of this provision by the Buyer shall incur a fine payable to JKF Industri of DKK,. The fine shall be payable for each breach of the provision, and if the breach consists of continuation of a previous breach, the fine shall be payable for each 14 day period of continuation or part thereof. Payment of a fine shall not relieve the Buyer of the above obligations, nor prevent or constrain JKF Industri from claiming compensation for any loss JKF Industri may have incurred arising from the breach, in that payment of the fine by the Buyer shall not be included in calculation of JKF Industri s loss. In addition to the above, JKF Industri is entitled to take out an injunction. 9. Liability for defects and deficiencies and warranty claims Upon receipt of the goods sold at the Buyer s address, the Buyer shall immediately perform a thorough examination of the goods, including quantity and specifications. Should the Buyer wish to claim for any defects or deficiencies, including with regard to the quantity or specifications delivered, which the Buyer has or should have discovered in the course of thorough examination of the goods, a written claim shall be submitted to JKF Industri without undue delay and within 14 days of receipt of the goods at the Buyer s address. JKF Industri is entitled to reject any claims received after the expiry of the period stated above. JKF Industri warrants performing redelivery/remedy of goods which are defective or deficient due to material or manufacturing error for goods which the Buyer has not nor should have discovered by thorough examination for a period of 12 consecutive months after delivery. However, the Buyer shall submit a claim to JKF Industri immediately if discovering such defects or deficiencies. Defective or deficient goods will either be remedied or replaced within a reasonable period of time at JKF Industri s discretion. Modification/interference with the goods without JKF Industri s written consent releases JKF Industri from any obligation. Remedy/redelivery by JKF Industri of elements of a delivery shall be on the same terms and conditions as for the original delivery, including those stated in item 6. JKF Industri s obligation to remedy or redeliver does not, however, apply to any part of an order more than 1 year after delivery to the Buyer. Once liability for the order has been transferred to the Buyer, JKF Industri bears no responsibility for any defects over and above the obligations specified in this provision. 1. Force majeure The following circumstances are intended as examples of events resulting in exemption from liability should they prevent fulfilment of the contract: Industrial disputes, strikes, lockout or any other circumstances beyond the control of the parties, such as fire, war, mobilisation, unforeseen military call-up, acts of sabotage, requisitioning, confiscation, currency restrictions, import ban, export ban, riots, unrest, fuel shortage, general scarcity of goods, restrictions in power supplies and defects in deliveries from sub-suppliers or delays with such deliveries as a result of any of the aforementioned circumstances. It should be specifically noted that the above is not an exhaustive list of examples, and there may be other examples that come under limitation of liability. If delivery is temporarily delayed by one or more of the aforementioned circumstances, the delivery date will be correspondingly postponed. If delivery is prevented for more than 12 weeks, JKF Industri is entitled to cancel the relevant contract without liability. 11. Returns Items sold can only be returned by prior written agreement, and upon obtaining a returned goods order number. Return will be at the Buyer s expense and risk and should include JKF Industri s invoice number and the date of the original delivery. Returned goods will be credited once they have been inspected and approved, normally to the value of 8% of invoice price (unless otherwise agreed in writing), less any costs incurred by JKF Industri for inspection, preparation or repair. If JKF Industri is charged for shipping costs etc., JKF Industri is also entitled to demand these be refunded by the Buyer and to offset these against any claims by the Buyer against JKF Industri. 12. Product liability JKF Industri is not liable for damage to property or effects that occur while the item is in the possession of the Buyer. Neither is JKF Industri liable for damage to products manufactured by the Buyer or to products of which these form a part. JKF Industri is not liable for any operating loss, lost earnings or other indirect loss. To the extent that product liability may be imposed on JKF Industri with regard to third parties, the Buyer is obliged to compensate JKF Industri to the same extent that JKF Industri s liability is limited as per the above. These limitations to JKF Industri s liability do not apply if JKF Industri is guilty of gross negligence. If a third party puts forward a claim against one of the Parties for compensation with reference to this point, that party must immediately inform the other party. The Buyer can be sued at the same court that handles any claims for compensation against JKF Industri, in consequence of damage alleged to have been caused by one of JKF Industri s deliveries. JKF Industri s product liability can never exceed the cover JKF Industri has for product liability insurance. 13. Compensation Notwithstanding the above, JKF Industri cannot be held liable for any indirect loss such as operating loss, consequential loss, loss of profit etc., which a defect or deficiency could cause the Buyer or a third party, including indirect loss etc., arising as a result of delayed delivery or defects/deficiencies in the goods sold. Any compensation claim against JKF Industri cannot exceed the invoice value for the goods sold. 14. Invalidity Should one or more of the provisions in these terms be deemed invalid, illegal or nonapplicable, the validity, legality or applicability of all other provisions shall not be affected or lessened as a result thereof. 1. Jurisdiction and court of venue All disputes between the parties shall be settled under Danish Law including the Danish Sale of Goods Act, but with the exception of Danish jurisdiction rules. The International Sale of Goods Act (CISG) shall neither be wholly nor partially applied. Any dispute regulated by the terms shall be resolved by arbitration at the Danish Institute of Arbitration, according to the institute s rules, which apply when an arbitration case is brought with the amendments stated below. However, the Parties agree that the arbitral tribunal shall consist of 3 members, of whom each party will appoint one member, and the Danish Institute of Arbitration will appoint the tribunal chairman. If a party fails to appoint a member within 14 days of being requested to do so by the Danish Institute of Arbitration, the institute will appoint a member on behalf of that party. The tribunal shall sit in Hadsund. The original version of this document is in Danish. In the event of discrepancies between the Danish and English versions, the Danish version will take preference.

Fan types Technical catalogue: General Section: Page: 2/6 Revised: 1.6.21 Radial fan with P-impeller General Resistance occurs in all forms of air transport due to friction which means that overall pressure is reduced in the flow direction. To effect and maintain air transport, pressure has to be increased at some stage to compensate for pressure loss. This is usually achieved in fan systems using radial and axial fans designed to boost air flow in the direction of the outlet. Definitions Static pressure: Dynamic pressure: Total pressure: p s p d p t Static pressure is designated positive or negative depending on whether there is over or under pressure in the duct. On the other hand, dynamic pressure is always positive and depends on the speed of the air in the duct. Total pressure must always be equal to the sum of the static and dynamic pressure at the measurement point, which can be expressed as: p t = p s + p d Volume flow A fan s effect is always based on actual volume flow through the inlet. If the volume flow is indicated at a temperature different to that at the fan in a given operating situation, it must be corrected. Temperatures The graphs indicate 2 C. Fans can be used for temperatures up to 6 C without physical modification. At temperatures other than 2 C, the air density is changed. This means it may be necessary to adjust the min -1. At temperatures over 2 C the fan will generally be giving reduced effect in relation to the rise in temperature. For high temperatures, the following should be taken into consideration: bearings and lubricant - whether the fan should be fitted with cooling wings whether the motor should be supplied with extra cooling (particularly important for frequency regulation). For temperatures in excess of 6 C, extra cooling is required. Radial fan with T-impeller Fan types Motors and fans are usually supplied as a unit. JKF has designed its fans for optimal performance, and it is vital to select the right one for any given task. The speed at which the fan is to run can be seen from the graph for that fan. The power input required depends on resistance in the system. There are many types of fan impeller, each of which is designed for a given task: Radial fan with P-impeller Radial fan with T-impeller Radial fan with P-impeller Has flat backward-inclined blades and is designed for clean air transport. This type has the following properties: High efficiency Robust construction Only small variations in volume flow if resistance fluctuates. Radial fan with T-impeller Has backward-inclined blades and is designed for transport of a range of materials. This type has the following properties: Medium and high-pressure versions Robust construction High degree of self-cleaning Can handle large material volumes Special version available for transport of plastic and paper All fans are ATEX-certified in accordance with Directive 94/9 EF. 4

Fan selection Technical catalogue: General Section: Page: 3/6 Revised: 31.8.211 Useful effect Theoretical pressure increase is never achieved in practice, as all fans work with several unavoidable types of loss, including: Friction loss in housing and impeller Thrust loss at blade inlet Leakage between housing and impeller Loss due to impeller friction Loss in motor, belts and bearings JKF states the total useful effect. The useful effect for a given operating point indicates the relationship between the utilisation effect (air effect) and the power input (shaft effect). The utilisation effect is the product of volume flow and total pressure increase. The useful effect of the fan can be expressed as follows: η ν = q ν p 1 P and its effect consumption as: P = q ν p 1 [W] η ν where P = shaft effect [W] of the fan q v = volume flow [m 3 /s] p 1 = total pressure increase [Pa] η ν = useful effect of the fan [decimal fraction] Any loss from the belt drive and motor have to be added, so that total effect consumption can be expressed as: P 1 = q ν p 1 η v η r η m where η v = useful effect of the fan η r = useful effect of the belt η m = useful effect of the motor Fan diagram For description of fans for specific solutions, the following parameters are required: Volume flow Pressure increase Effect consumption min -1 Useful effect Noise intrusion Capacity regulation of fans All fan systems of any size can be fitted with capacity regulation to match volume flow to the usage patterns of the plant. Depending on operating requirements, fan performance can be regulated in several ways: Pole-switching between two fixed speed regulator values (2-speed motor) Twist throttle on fan inlet side min -1 regulation using a frequency transformer A combination of the above Using a frequency transformer maintains the fan useful effect almost unchanged across the entire regulation range and avoids noise being created during regulation. Accessories Twist throttle is available as a component 6 Hz impeller for transport fan The impeller has to b e modified for 6 Hz direct driven transport fans. Belt-driven fans are adjusted via the pulleys. The SKF bearing housings on the fans are types SNL TA, with V-gasket TSN A. Surface treatment The products are finished in powder paint or galvanised with a zinc thickness of min. 2 g/m². The finish consists of a specified primer treatment and then powder paint. Primer treatment: Internal/external sandblasting to SA 2. Water-based degreasing in a multistage closed washer, where the items are washed with 6 C hot degreasing liquid. After this, phosphating and 2 rinsing are carried out. The process is environment friendly and effective. Primer: Zinc priming of all sharp edges 7 µm Topcoat: Polyester powder of industrial quality, min. 8 µm All painted products are standard blue RAL 1. Can be supplied in other colours at extra cost. Test All fans are tested for function and vibration. When ordering, JKF requires the following information: Fan type air volume air temperature - pressure material transport/ nature installation conditions noise levels effect consumption - motor motor integrity class operating time - surface treatment, zone placing (ATEX) and any other requirements. Fan graphs are based on a density of 1.2 /m³ equivalent to air density at 2 C and barometric pressure of 11.3 kpa.

How to read fan graphs Technical catalogue: General Section: Page: 6/6 Revised: 1.6.21 In practice it is highly likely that the operational point for a fan will not appear on the graphs referring to useful effect, but between them. Determination of values for the operational point selected can be calculated using the following formulas: Total useful effect η T = p Q 9,81 1 P p = Total pressure read from graph in mm WG Q = read from graph in m³/h P = Power input to electric motor in kw When calculating useful effect When only working with power input to the impeller, the following formulas can be used: For direct drive fans the useful effect is η D = η T + 1% For indirect drive fans the useful effect is η ID = η T + 1% + 6% For noise calculation The following formulas can be used along with sound measurement apparatus: min -1 adjustment: L 2 = L 1 + 6 log n 2 n 1 L 1 = Noise level at min -1 n 1 n 2 = New min -1 Noise level at various distances: L PA = L WA - (2 log R) + (1 log Q) - 11 db(a) L WA = Noise effect R = Distance between noise source and receiver Q = Direction factor Q = 2 (hemispherical spread) Q = 4 (quartspherical spread) Q = 8 (octaspherical spread) hp 2.8 2.6 2.4 2.2 2. 1.8 1.6 1.4 1.2 1..8.6.4.2. 16 8 4 6 2 4 18 16 14 18 14 16 12 16 12 14 1 14 1 12 8 12 8 1 6 1 6 2 kw 2. 1.8 1.6 1.4 1.2 1..8.6.4.2.

Twist throttles Technical catalogue: Accessories Section: 8 Page: 2/9 Revised: 1.6.21 L A Dn d1 H Dimensional specifications are given in the table below. A centrally driven twist throttle, type JK-LA, is used to regulate air volume to the fan in the most energy-efficient way. The twist throttle is mounted directionally with flow in the direction of the arrow. Regulation is achieved by all the twist blades turning synchronously between - 9 to create pre-rotation of the air flow entering the fan. The load on the fan impeller is reduced and consequently power consumption. The JK-LA twist throttle can reduce total energy consumption by up to 4%. The turning mechanism in the hub is designed as a sealed, compact and robust unit with a minimum number of components and extremely low friction. The twist throttle requires no servicing and can be used as a throttle valve.
