It is designed for optimum performance and low operating costs in both new and replacement systems. The Alpha 2000 saves space, energy, and material and labor costs with 40% more media area than the standard capacity Alpha Cell filter. Save Space Alpha 2000 HEPA filters operate at 500 fpm (2000 cfm for a 24” x 24” size) at 1.35 inch w.g. clean pressure drop versus conventional Alpha Cell filters that operate at 250 fpm and .80 inch w.g. clean pressure drop. Construction A popular construction option consists of 16 ga. galvaneal frames and moisture-resistant microfine wet-laid fiberglass media folded over hemmed- edge low amplitude corrugated aluminum separators. The filter pack is bonded to the frame by a fire- retardant urethane elastomer to provide a rigid leak-free assembly. Save Energy Alpha 2000 filters in a conventional HEPA filter bank impose a lighter load on the fan when operat ed at conventional 250 fpm velocities during the life of the filters. The Alpha 2000 99.97% and 99.99% high capacity 24” X 24” X 11.5” filter has a clean pressure drop of 1.0 inch w.g. at 1500 cfm, compared to standard Alpha Cell filters with a clean pressure drop of 1.50 inch w.g. at the same air flow. Save Replacement Material and Labor Costs Savings are significant with high capacity Alpha 2000 filters. They operate at lower velocities and provide life cycles up to three times the life of standard capacity filters. Savings are achieved in replacement materials and labor costs as a result of fewer filters. 0 125 250 375 500 625 Air Velocity (fpm) Pressure Drop (in. w. g.)

To make a Separator Style filter, the media is folded over corrugated aluminum separators with hemmed edges to separate the pleats in the filter pack. Flanders manufactures its own filter media, enabling it to develop a unique manufacturing process for the production of Pureform Separatorless HEPA Filters. In one manufacturing operation, Flanders produces a self-supporting and self-separating Pureform Media Pack. The Pureform Filter offers many advantages over conventional Separator Style HEPA Filters: • More usable media area for longer service life because of higher dust holding capacity • Reduced cost of ownership because of longer service life • Maximum utilization of the media • Can handle some harsh environments which may attack aluminum separators • Media pack can be incinerated • Media is 28 mils thick, which is significantly thicker than conventional 15 mil media used in Separator Style HEPA Filters Alpha 2000 with Separator Style Media Pack Alpha 2000 with Pureform Media Pack Flanders Filters - Foremost in Air Filtration Toll Free: 1-800-637-2803 Frame Materials: Alpha 2000 Filters are available in a variety of wood and metal frame materials such as particle board, plywood, galvanized steel and stainless steel. Gasket and Fluid Seal: The standard gasket seal is 0.75” x 0.25” neoprene for installation on either the upstream, downstream or both sides of the filter. The standard Fluid Seal is Flanders Blu-Jel® Seal which is a two - part silicone material suitable for temperatures up to 390°F. Faceguards (Optional): Faceguards are used to protect the filter media from mechanical damage. The typical faceguard material is expanded aluminized steel. Galvanized 4 x 4 mesh welded wire and Type 304 stainless steel are also available. Underwriters Laboratories Qualification: Alpha 2000 Filters are either UL900 Class 1 or Class 2 listed depending on materials of construction. UL 900 Class 1 — Flanders HEPA Filters are UL 900 Class 1 rated except those filters manufactured with nonfire- retardant wood frames. Upon request, the filter will have a stamp indicating compliance with UL 900 Class 1. UL 586 — UL 586 is typically required for Nuclear Grade HEPA Filters. Many of the Flanders non-Nuclear HEPA Filters meet the requirements of UL 586. To be listed under UL 586, filters must be submitted to Underwriters Laboratories for extensive testing including spot flame and environmental exposure to heated air. Upon request, a numbered UL 586 label certifying that the filter meets Standard 586 can be applied to the filter (maximum size is 24” x 30”). Banks: Alpha Frames are designed for Alpha 2000 filters in built-up filter banks. Ea...
