FlexPak™ FA Series Extended Surface Supported Pocket Filters Better Air is Our Business ® Applications FlexPak™ FA Series filters provide medium to high efficiency air filtration in commercial, industrial, and institutional buildings. A wide range of sizes, efficiencies, and airflow capacities are available. FlexPak FA filters can be installed only in systems equipped with compatible basket type wire retainers. Performance Plus Design Low-Cost, Dependable Operation The high dust holding capacity of FlexPak FA Series filters results in long service life. Coupled with an economical purchase price, these filters provide low operating cost. A wire retainer holds the pockets firmly in position, preventing flutter during start-up, shutdown, and continuous operation of the fan. Eliminating flutter keeps dirt from shaking loose and returning to the airstream. Directly Interchangeable FlexPak FA Series filters are interchangeable with current manufacturers’ designs of preformed, collapsible pocket filters. No new frames or wire retainers are needed. All FlexPak FA Series filters of the same size and depth are interchangeable to allow efficiency upgrades without modification to the filter bank. Space-Saving Design The pre-folded pocket design requires minimum storage space. Uniform Pocket Spacing Speeds Installation FlexPak FA Series filters have spacer strips on the air entering and air leaving sides of the pockets. These strips assure accurate pocket alignment which simplifies inserting the filter into the wire retainer. The pocket spacer strips are stapled to the support panels with the media sandwiched in between, sealing the pocket edges. This method of securely fastening the pockets to the support panels also prevents the media from being torn loose during shipping, installation, or in operation. The spacer strips on the air leaving side extend the entire depth of the pockets to prevent media damage caused by the wire retainer as the filter slides into the basket. FlexPak FA Series - Filter Assembly FlexPak FA Series filters consist of preformed pockets 8, 12, or 24 inches deep. The media is bonded on the top and bottom to a moisture resistant fiberboard support panel. The filter fits into a wire retainer that holds the pockets firmly in place during operation. A sealer frame secures the filter to the holding frame. FlexPak FA Series filters are available in all popular sizes and can be installed in front, rear, and side access systems. Choose from four efficiency levels: 30%, 50%, 80%, and 90%. Economical replacement filters for HVAC systems equipped with basket-type wire retainers. Pocket spacer strips assure accurate alignment with the wire retainer for easier installation.
