24" X 24" X 1" Perm-A-Foam Filter

The Smith PERM-A-FOAM filter is a permanent pleated filter that provides 40% more filtering area than a regular flat filter. A sandwich structure consists of two layers of heavy expanded aluminum separated by a 1/8" polyurethane foam pad. This pad is then encased in a heavy aluminum frame commercially known as 3003-H14, .025 in thickness expanded with .020 strand. The foam is a 20 PPI, non allergenic, non toxic material, which can easily be cleaned by brushing off excess dirt and washing under hot water. Mild detergents can be used if required. The filter retains 290 grams of dust per 2.25 sq. ft. (20 x 20 filter). Resistance when clean is 0.05 w.g. at 350 FPM air velocity. Maximum resistance at capacity is 0.335 w.g.

The PERM-A-FOAM can be used in any application where a fiberglass or pleated filter is used. The ideal permanent air filter to be used in air conditioners and furnaces.
