Series 1532 Inflow Cabinet After installing the HEPA filters the discharge air should be monitored to ensure proper filtering efficiency HEPA Filters Sizes — The HEPA filters used in the units are of standard industrial sizes. The size will be: 23-5/8 in. x 47-5/8 in. x 3 in. or 24 in. x 48 in. x 3 in. 24 in. x 72 in. x 3 in. Media pack — 2.875 with aluminum separators. Filter Frames — Extruded aluminum 3 in. or 3-1/2 in. thick Protective screen on the upstream side of the filter. Gasket — 1/4 in. x 3/4 in. closed cell, gasket on downstream side of the filter. Filter Efficiency — 99.99% on 0.3 Micron (Standard) “HEPA”; 99.99% on 0.12 Micron “ULPA”; Other HEPA Filter System The HEPA filter system consists of two basic members: the absolute HEPA filter and a flexible duct to form a modular component. All HEPA filters purchased by Clean Air Products have been Polystyrene bead tested to Shipments Clean Air Products takes every reasonable precaution to ensure that your laminar air flow cabinet arrives without damage. However, damage can occur in any shipment, and it is important that you note visible damage immediately with a notation on the consignee’s copy of the freight bill. Terms are F.O.B. factory, unless otherwise stated. Your inspection of either visible or concealed damage is the basis of your filing claim (which you must do at once) against carrier. An inspection then must be made to verify the claim against the carrier. Performance Specifications All equipment is thoroughly inspected at the Clean Air Products’ factory at the time of shipment. Quality control is maintained by constant surveillance over the product, beginning at receipt of purchased material and concluding with a final inspection which certifies performance to Class 100 conditions of Federal Standard 209D, as well as to the unique requirements of each project. In all instances where product quality cannot easily be assessed on the end item, the product is inspected during subassembly fabrication. All electrical components are UL approved; all mechanical components are fabricated or purchased and inspected to performance requirements before assembly into the final product. All Clean Air Products’ products have been certified to meet or better the following specifications: General Description The Series 1532 inflow module comes in a variety of sizes and styles. Some of the included information will depend on the style of unit purchased. The Series 1532 units are constructed of stainless steel as standard. This finish is designed to be compatible with normal cleanroom environments. When cleaning is required, a mild soap and water solution is recommended with a distilled water rinse. The distilled water is recommended because it does not have any mineral hardness that may leave a “mineral film” that can be wiped off and cause particulate contamination. Care should be used when cleaning the protective grill doors so the HEPA filters are not damaged during the cleaning process. NEVER attempt to clean the HEPA filter except by purging the filter. Rubbing or blowing the HEPA with high pressure air will damage the filter and cause leaks. The system is designed to draw air into the wall mounted filters where it is filtered and then discharged back into the space. The system is not designed to work with flammable vapors, odors or corrosives. Protective garments and respirators should be worn by personal to prevent exposure to materials being used within the system. A safety and use procedure should be developed by the purchaser taking in account the materials being used and airflow patterns after equipment being installed inside the hood. The operation should be monitored to ensure that all materials are being contained within the enclosure.

Series 1532 Inflow Cabinet Technical Data continued meet Mil Standard 282 and are tested for leakage for 99.99% removal of all particulate contaminants greater than 0.3 micron. Prefilter The Prefilter is made of 2-inch thick disposable, non-woven framed fiberglass media, a nominal efficiency of 40% by NBS Test Method using atmospheric dust or better. Higher efficiency filters can be used, but will increase the system pressure drop. This may require an increase of the blower RPM to increase the suction pressure across the filters. Installation 1.

Avoid fanning papers, books, arms, coats and fast walking in front of the hood. Air currents will cause contaminate to exit the interior. A line should be drawn on the floor to show the safe working zone. All work is performed inside of this line. 5. The air is being drawn into the enclosure. Turbulence will develop 7. Spills should be cleaned up immediately. Sponge the liquid near the HEPA filter...

Care should be taken when moving the filter into place that the gasketting is not folded or damaged when positioning the filter. Reattach the prefilter frame. The filter gasket should be compressed about 1/16 to 1/8 inch. This is about 1 to 2 turns of the nut with the gasketting just touching the frame. Over tightening the springs can damage the filter or the springs. Insert prefilters into frame and reattach the media frame. This frame should not crush the...

Technical Data continued Prefilter Media The media is 1 inch thick with a “tacky” face to help catch and hold any particles. This media should be changed when it is dirty. Prefilters The prefilters should be changed when they are dirty. They are of a standard industrial size. HEPA Filters The HEPA filters should be changed when you are not able to maintain the proper face velocity out of the filter or when a filter becomes damaged. The life of the HEPA filter is dependent on...
