Pockets are also fully welded instead of stitched. That means less chance of pin-hole leaks and very high blow-out strength. Headers on SwissAire bag filters are all 16 gauge galvanized steel, not plastic that can crack or warp. SwissAire synthetic, self supporting bag filters are designed for use in most commercial or industrial HVAC systems where medium to high efficiency filtration is required. SwissAire Filters are available in minimum efficiency levels of 50%, 60% and 90% per ASHRAE Standard 52.1 test methods. Offered as MERV 8-15 per ASHRAE Standard 52.2 SwissAire bag filters are UL 900 Class 1 listed. Installation Considerations SwissAire bag filters may be installed in Flanders ASTRl Holding Frames, K-Trac Filter Framing Modules, Sureseal Side Access Housings, or in similar existing hardware. ASTR Holding Frames are riveted together to form a bank and may be installed for upstream or downstream service. K-Trac Filter Framing Modules are especially suitable for medium to large built-up filter banks. Smaller systems and systems with minimum upstream access space are best served using Sureseal Side Access Housings. Physical Data Media: A nearly rigid, high strength synthetic medium. -Progressive density fiber matrix designed for high dust holding capacity. -100% synthetic medium performance results from strictly mechanical particle collection mechanisms. Performance of the product is not afffected by preconditioning step proposed to ASHRAE 52.2 Pocket Retainer: Corrosion resistant steel or aluminum Header: 13/16” wide corrosion-resistant steel Actual Header Face Size: Nominal size less 5/8” (e.g., a nominal 24” x 24” filter header is actually 23-3/8” x 23-3/8”) Important Features • Nearly rigid pockets are self supporting and allow for full media use with no pocket sag • 100% synthetic media • Low initial pressure drop provides longer life. • Welded pockets, no stitching for better integrity and higher blowout strength. • Wide range of cartridge depths, efficiencies and operating capacities are available. • MERV 8-15 • UL 900 Class 1 Flanders Presicionaire - Foremost in Air Filtration Toll Free: 1-800-347-2220 Swissaire media is 100% synthetic composed of fine fibers in a progressive density structure for optimum pressure drop performance and high dust holding capacity. Corrosion free galvanized metal header will not crack or warp. Media is fully encased and sealed, ensuring no bypass and exceptional burst strength. 100% synthetic medium perform- ance results from strictly mechani- cal particle collection mechanisms. 50%, 60%, 90% per ASHRAE 52.1 Performance of the product is not afffected by preconditioning step proposed to ASHRAE 52.2 Corrosion-resistant pocket retainers Fully welded pockets provide a leak-free design and exceptional burst strength greater than 12.5 inw.g.

Application Guidelines Prefilters SwissAire bag filters should be installed with pockets vertical wherever possible. It is acceptable to install 24” x 12” face size filters with pockets horizontal if necessary to meet the size requirements of the filter banks. Gasketed Headers SwissAire bag filters installed in Flanders K-Trac Filter Framing Modules or Sureseal Side Access Housings require polyfoam gaskets on opposite header sides to prevent air bypass. To specify SwissAire bag filters with gasketed headers, add suffix ”SA” (side access), “GU” (upstream), “GD” (downstream) and “GS” (sides) to model number. Properly selected bag filters without prefilters will generally require changeout annually in typical HVAC applications. Because of the frequent maintenance expense and increase in fan kW input using prefilters, they are often recommended with 90% efficient SwissAire final filters. However, the energy cost to operate a prefilter s...
