PreVent® Equipment Protection Air Filters

Permatron’s patented PreVent® Equipment Protection Air Filters can save you thousands of dollars and man hours, in equipment downtime and maintenance costs by preventing debris from entering the system. Manufactured with UV protected polypropylene, a washable media, these filters can be used in hostile outdoor and indoor environments. Filter installation requires no system modifications or electrical hookups. Custom made to exact dimensions with a steel or vinyl frame, filters are easily affixed to the outer perimeter of the air intake with our unique, patented hook/loop or magnetic stripping, as well as grommets and mounting kits.
