Permatron's Patented Equipment Protection Filters are designed with permanent, washable UV protected media, which draws in and traps airborne particulates before they can enter the system.  Available in multiple styles, we offer our PreVent® Model R with a single or double layer of black polypropylene media encased in a rigid steel frame; PreVent® Model U with a single or double layer of black polypropylene media encased in a flexible vinyl edge with single or double stitching; and PreVent® Model BHA with a single layer of black PVC coated polyester high abrasion media encased in a flexible vinyl edge with single or double stitching.  We also offer 3-Dimensional styles with elastic edging for fan guard bonnets, vent and exhaust caps and ceiling air diffusers.

Independent testing, conducted by UL Laboratories, showed PreVent® Filters cause less than 1% change in system discharge pressure.  The filter has a low .02-.05 in. w.g. initial resistance to air flow.
