Using Standard Alpha 95 and Alpha Cell and High Capacity Alpha 2000 HEPA Filters
1. Height and Width code: the first numeral represents the number of 24 in. x 24 in. filters high and wide. See also
Model Number Development on page 3.
2. Standard housing depth is 23-1/4 inches with or without an optional prefilter track.
3. Housings greater than four wide must have filter removal from both sides.
4. Capacities shown are based on nominal 12 inch deep filters.
A flange in the housing mates into a
gel-filled channel on the filter. The
gel seal guarantees filter-to-frame
sealing and is recommended for
critical applications.
A spring-loaded filter clamping
mechanism is used to maintain seal-
ing pressure for gasketed filters. The
gasket seal is suitable for many
applications.
