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