The Rupp Air Pollution Control Unit, RPCU Series, is designed specifically for the removal of smoke and grease particles from the air stream of commercial kitchen exhaust systems and to eliminate or reduce odor to an acceptable level if equipped with the optional odor control section. The RPCU is designed for use with a Rupp Air high efficiency self-cleaning or baffle ventilator but may be used with other high efficiency exhaust hoods.

The typical RPCU includes a washable steel pre-filter and disposable, high efficiency, (MERV 14) media filter. A HEPA final filter module is available for smoke control, and odor control is handled via an optional 50/50 blend carbon/permanganate module. Sizes range in capacity up to 20,000 CFM. The RPCU is ETL listed to standard UL710 and is suitable for indoor or outdoor installations.
