Ceiling-Filters are Intake Filters used in Spray Booths that have a Ceiling Plenum. They can also be used in Paint Booths that are designed so that the Intake Air requires a large pad of filtration media.
These filters are of high density to retain particles up to 10 microns and they last from 6 to 12 months depending on the environment air quality and on the design of the pre-filtration system.
