PreVent Equipment Protection 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 permanent/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 your exact dimensions with a steel frame or vinyl edge, 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.

PreVent® will protect any type of equipment from airborne debris. Drawn into the equipment via air intake, the resulting dirt build up impacts the equipment’s ability to work efficiently. Whether your equipment is used for production, process or environmental air handling, no business today can afford unnecessary downtime.

Easy cleaning: Media can be easily cleaned in place with a broom, shop vacuum or rinsed clean with water as needed. Inherent electrostatic charge in media captures fine particles, as well as larger debris. UL Classified As to Flammability Only.

MagnaMount®, with a powerful earth magnet, is a fast and easy way to install PreVent cottonwood screens without screws!
