High Capacity HEPA Filters

See component chart on page 87.

High Capacity Design

The Alpha 2000 High Capacity HEPA filter is avail- able in a nominal 12” depth configuration. It is designed for optimum performance and low operat- ing costs in both new and replacement systems. With 40% more media area than the standard capacity Alpha Cell filter, the Alpha 2000 saves space, energy, and material and labor costs.

Save Space

Alpha 2000 HEPA filters operate at 500 fpm (2000 cfm for a 24” x 24” size) at 1.45 inch w.g. clean pressure drop versus conventional Alpha Cell filters that operate at 250 fpm and 1.0 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 separa- tors. The filter pack is bonded to the frame by a fire-

retardant urethane ela tomer to provide a rigid leak-free assembly.

Save Energy

Alpha 2000 filters in a onventional 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 12” filter has a clean pres- sure drop of 1.1 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 stan- ard capacity filters. Savings are achieved in replacement materials and labor costs as a result of

fewer filters.
