ASHRAE 85%: EA-85xx	ASHRAE 95%: EA-95xx

General

EA Series Replacement Air Filters are pre-formed, extended surface deep-pleated cartridges for use with existing hardware in commercial and industrial HVAC systems. EA Series filters are available in average efficiency ranges of 25-30%, 50-55%, 80- 85% and 90-95% when tested according to ASHRAE Standard 52.1 methods. EA Series filters are UL 900 listed Class 2.

Construction

EA filter media is a non-woven cotton and synthet- ic blend (25% efficient) or moisture-resistant micro- fine lofted glass fiber (55%,85%or 95% efficient). The media is reinforced with a non-woven remay backing and formed into a “pack” which is then hot- melt bonded top and bottom to 1/16” thick stiff mois- ture-resistant fiberboard panels. Alignment of the pleats in the media pack is carefully controlled dur- ing the bonding operation to facilitate insertion of the cartridge into the wire media retainer during installation. The completed filter is folded before being boxed to minimize shipping and storage vol- ume.

Application

EA Series cartridge filters are designed to be used only in existing hardware as pictured below. This hardware consists of metal holding frames, sealer frames and wire basket-type retainers that may be used in either front or rear-loading built-up filter banks or side a ess housings.

EA Cartridge Disposable Replacement Air Filters are fully interch nge ble with other manufacturers’ cartridge filters nd h rdware. Units of one effi- ciency may be repl ced in the same system hard- ware with similar size and depth units of another efficiency. When upgrading efficiencies, be sure to check the capability of the fan to overcome the increased pressure drop.
