2 Quality Assurance Any industry that has dangerous process or exhaust gases and/or particulates has a vital concern for the health and safety of personnel. In addition to corporate concern, the United States Government has dictated that safety equipment meet minimum safety standards. Any equipment sold to meet these minimum standards has to be manufactured using accepted Quality Control procedures. Flanders/CSC Corporation has developed a Quality Assurance program to assure that the product or service provided meets these standards. This program addresses the entire range of Flanders/CSC involvement, including the purchase of raw materials, the shortage of these raw materials, incorporation of these materials into a product or service, testing this product or service, and then shipping it to its destination. The program of Flanders/CSC has been audited many times, and each time the program has been acceptable. An uncontrolled copy of the program manual is available with each request for Quality Assurance information. Like any dynamic document, the program is continually being revised to include recent issues of standards and specifications in order that Flanders/CSC may use the latest state-of-the-art methods in providing its products and services. The Quality Assurance Program at Flanders/ CSC Corporation has been audited and approved several times by the Nuclear Utilities Procurement and Inspection Committee, NUPIC.

HEPA filters are factory tested to meet the requirements of IEST RP-CC001.3 for Type A, B, C, D, E or F filters: Industrial Grade Nuclear Grade Laminar Flow Grade Bio/Hazard Grade HEPA VLSI ULPA Pharmaceutical Grade Test results appear on both the filter label and upon the filter carton label. An additional quality assurance test report is kept on file and is available upon request. Flanders recommends that all HEPA filters be tested in place by qualified personnel to ensure that the filters have been correctly installed. Flanders service personnel are available for installations, supervision of installation, testing and certification of compliance to industry and government standards and instruction of the owner s personnel in testing and maintenance procedures. Flanders does not guarantee that its equipment will operate at the performance levels given on the identification labels or in the catalog specifications under all conditions of installation and use, nor does Flanders/CSC guarantee the suitability of its product for the particular end use which may be contemplated by the buyer. For best results, it is recommended that the buyer supply complete information about the operating conditions of the ventilation system to Flanders/CSC for evaluation. When the system components are supplied to the buyer or his agent for final installation and assembly in the field, it should be under the supervision of factory trained personnel. Failure to adhere to this recommendation or failure of the buyer to have filters timely retested and serviced will nullify or limit any warranties which might otherwise apply and may result in a compromised installation. 2

5 RPF Radial Flow Side-Access Filter Housing: Introduction Flanders/CSC Containment Housings: RPF-Series Bag-In/Bag-Out Housing The RPF-Series Gel Seal containment housings are typically used on critical processes where dangerous airborne particulate must be prevented from entering the atmosphere. The Flanders/CSC RPF-Series bag-in/bag-out filter housing allows for the installation of radial flow HEPA filter elements in a low CFM ventilation system (e.g. glovebox, isolator). The RPF-Series filter housings are designed for particulate filtration. One of the primary uses of HEPA filters is the containment of toxic materials. When filters become contaminated in-service with these materials, a method for their removal without direct operator contact is necessary. The bag-in/bag-out feature of the RPF- Series allows the operator to change filters without coming into direct contact with the toxic materials (such as viable organisms, radioactive dust and carcinogens) that have been collected by the filter element during its service life. RPF-Series Bag-In/Bag-Out: The RPF-Series housing features a side access bag-in/bag-out port which allows filters that have been contaminated in service to be removed from the housing without direct contact with service personnel. Basic housings are available in 1H1W, 2H1W and 3H1W configurations, allowing filters to be removed from separate access door. Units may be joined to build systems with capacities ranging from 1,000 CFM to 60,000 CFM (based upon 2,000 CFM per filter). Many custom options are available, including static pressure taps, test ports, transitions, dampers and in-place test sections which allow the operator to perform filter system efficiency test without having to enter the system or otherwise disrupt its operation. The RPF-Series bag-in/bag-out housing is a side servicing filter housing that has been designed to meet the air filtration needs of industries and research facilities that handle dangerous or toxic biological, radiological or carcinogenic materials. To minimize exposure to harmful contamination while replacing and handling dirty filters, the RPF- Series housing incorporates a ribbed bagging ring behind the access door, over which a PVC bag is attached. Once the initial filters are installed and the first bag is attached, all filters, both dirty and new, are handled through the bag. These procedures are summarized on Page 9. Manufactured under stringent quality assurance controls, RPF-Series housings are subjected to thorough inspections and leak tightness tests before leaving the factory, and are guaranteed to pass DOP in-place tests. This guarantee is contingent upon the use of properly installed Flanders Radial Flow HEPA filters. 3

7 RPF Radial Flow Side-Access Filter Housing: Construction Details â Blu-Jel Seal The filter-to-housing fluid seal is effected between the housing and the filter by means of a circular knife edge in the housing. The knife edge mates into a channel on the upstream end of the filter. The channel is filled with a viscous non-drying sealing compound. AIR FLOW Metal Grill Filter Pack Housing Material The standard RPF-Series filter housing is constructed from 14 and 11 gauge Type 304 stainless steel. Housings are also available in Type 304L, 316, and 316L construction. Some hardware on the housing will be 300 series stainless steel. All pressure retaining joints and seams are welded airtight per ASME Section IX, with no visible pores. All welds shall be free of burrs and sharp edges. Door Latches A minimum of four tie-down latches are provided per access door. The latches pivot away from the bag-in/bag-out port after release so they do not impede the bag-in/bag-out process. The knob of the door latch is designed to spin free for door removal. Figure 2: Radial Flow HEPA â See Figure 3 for Blu-Jel Seal Knife Edge Filter Pack Door Latch Open â Blu-Jel Filled Channel Figure 3: Blu-Jel Seal Metal Grill Temperature Rating The standard housing is rated for degrees F. High temperature bags, straps, and gaskets are available to go up to 400 degrees F. Door Latch Closed 5

8 RPF Radial Flow Side-Access Filter Housing: Construction Details Bag-In/Bag-Out Port The housing s bag-in/bag-out port is designed so that a heavy duty PVC bag can be securely fastened around it after the original filter has been installed. When the door is eventually removed to change the filter, the bag provides a barrier between the operator and the contaminated filter. When the door is closed, the bag remains inside the door., The RPF-Series change-out port, accessed by the door removal, has two (2) ribs on the bagging ring to facilitate the bag-in/bag-out procedure. Bagging Ring Figure 4: Bagging Ring 6 Shock Cord 2nd Rib Change-Out Port Bagging Ring Housing 1st Rib Bag Security Strap Security Strap A one-inch wide nylon security strap provided with each RPFSeries filter housing fits around the lip of the bag-in/ bag-out port, in between the two ribs and over the âmouth of the bag. This supplements the elastic band in the bag and helps reduce the possibility of the bag pulling away from the lip in case the filter is accidentally dropped during replacement. The strap is buckled with a D ring and has Velcro strips to secure the end. Pressure Rating Security Strap The standard housing is rated at positive and negative 20-inch water gage. Reinforcement can be added to reach higher pressures. Leak Testing The complete assembly pressure boundary is leak tested by the Pressure Decay Method, in accordance with ASME N Reaffirmed, Testing of Air-Cleaning Systems, Paragraphs 6 and 7. Readings are recorded once a minute for five (5) minutes. Flanders/CSC s standard acceptable maximum leak rate is CFM per cubic foot of housing volume at the design pressure for the housing pressure boundary. Door Gasket The door of the RPF-Series is sealed to the housing by means of a replaceable extruded closed-cell neoprene gasket adhered to the lip of the door. The gasket is designed to be field replaceable if needed.

9 RPF Radial Flow Side-Access Filter Housing: Construction Details Silicone gaskets are available as an option. PVC Change-Out Bag A PVC bag is included with each access door. The Flanders/CSC change-out bag is translucent and yellow in color with a clear section at the attachment end for change-out viewing. Door Gasket Cinching Strap A cinching strap is provided with each bag to tie off the slack in the bag during the interval between filter changes. The cinching strap prevents the bag from being drawn into the housing during normal operations. The strap is cinched at a point near the lip of the bag-in/bagout port, drawing the bag tightly across the port and allowing the slack to fall off to the outside. The slack is then folded flat and contained inside the door. Elastic Shock Cord An elastic shock cord is hemmed into the mouth of the bag for a firm fit when stretched around the bagging ring. The bag has three (3) built-in glove sleeves to facilitate the filter change out. Correct replacement bag sizes are engraved on the door label of each housing. Replacement bag size labels are also attached to the shock cord hemmed into the bag mouth. PVC bags of this design have been tested by an independent laboratory to prove the bag s operability at extreme temperature ranges of 0 F 130 F.

10 RPF Radial Flow Side-Access Filter Housing: Construction Details Filter Clamps A stainless steel filter clamp secures the filter during operation. The clamps are spring-loaded and have a rod handle that is turned 90 degrees by the operator to lock the filter in the sealed position. The filter clamping design is a variation of ASME AG-1 Section HA. AG-1 Section HA currently does not address radial flow filter housings: it is written for axial flow filter housings. The filter clamping design ensures Jel Seal filters are properly seated, but does not pull the filter off of the surface stated for axial flow filters. Baffle Plenum 8 Filter Clamps The RPF-Series housing features a permanently welded baffle plenum. The air entering the housing is diverted before reaching the radial flow filter element. Leak Testing Both the filter sealing surface and the complete assembly pressure boundary are leak tested by the Pressure Decay Method, in accordance with ASME N Reaffirmed, Testing of Nuclear Air Treatment Systems, paragraphs 6 and 7. Readings are recorded once a minute for 5 minutes. The maximum allowable leak rate for the filter-sealing surface is CFM per cubic foot of housing volume when tested at 10 inches water gage. The maximum allowable leak rate for the housing pressure boundary is CFM per cubic foot of housing volume when tested at 10 inches water gage. Quality Assurance/ Quality Control Quality Control/ Quality Assurance Flanders/CSC products are manufactured under a strict QA program that is highly respected throughout our industry. Our QA program incorporates quality control checks from receipt of materials through final clean up and packaging. Our shop process is set up to easily incorporate customer specified checks into our QC program.

13 RPF Radial Flow Side-Access Filter Housing: Construction Details Static Pressure Taps Static pressure taps allow the measurement of differential pressure across the filter. Taps consist of stainless steel 1 /4 inch half-couplings with brass plugs, and are located on the inlet and outlet connections of the housing. DOP Test Ports To allow in-place efficiency testing of the installed filter, a DOP injection port ( 3 /4 inch coupling with brass plug) is located on the inlet side of the housing. Sample ports ( 3 /8 inch couplings with brass plugs) are located upstream and downstream of the filter. Moisture Drains and Valves For applications with a potential for moisture condensation, an optional drain valve assembly is available. This assembly consists of a stainless steel 1 /2 inch half-coupling, close nipple, with a stainless steel ball valve and brass plug. When moisture drain valves are provided, it is recommended that a mounting base be used. Low Leak Test The Low Leak Test required in the Nuclear Air Cleaning Handbook, ERDA (Table 4.5) is offered as an alternative to the standard leak test. It is a considerably more stringent test, allowing a leak rate of no more than 0.2% of the housing volume per hour at a pressure of 10 inches water gage. This equates to CFM per cubic foot of housing volume. High Pressure Design Flanders/CSC can design special high-pressure RPF Series housings capable of pressures up to 15 PSI positive or 14.7 PSI negative. Welds are performed per ASME Section IX. Banding Kit The Flanders/CSC banding kit facilitates clamping off the bag between the housing and the spent filter. The kit contains a supply of 25 stainless steel bands and the tools necessary to perform banding operation. An instruction/ procedure manual is included in the banding kit. The kit provides a simple, but extremely effective barrier during filter change-out. Figure 5: Drain Valve Banding Kit 11
