PreVent® Washable Screens

Permatron’s patented PreVent® Equipment Protection Air Filter can save you thousands of dollars and man hours, in equipment downtime and maintenance costs by preventing debris from entering the system. Manufactured with 3-dimensional polypropylene, a permanent/washable electrostatic media, these filters can be used in many hostile outdoor and indoor environments. Filter installation requires no system modifications or electrical hookups. Custom made to your exact dimensions with steel frames or vinyl edges, 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 Washable Screens

PreVent® will protect HVAC air handlers, cooling systems, chillers, condensers, compressors, ground louver inlets and any type of industrial 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.
