Filter
Filter Size A A B B
Quantity - Size
Field-supplied external filters must be sized so as not to exceed 300 fpm air velocity through disposable fil-
ters. For internal filter use, a filter rack kit is included with all three phase models. Consult the instructions
supplied with that kit for replacement filter sizes. Filter sizes: A=20x20, B=20x30.
