Simply Powerful PreVent^® System Filter Screens

Keep your HVAC system and commercial air filters safe. PreVent screens Model U and Model BHA are flexible, vinyl-edged equipment protection air filters that capture airborne particulates before they can enter your HVAC system. Custom-designed to fit the exact perimeter of any outdoor air intake, PreVent is UV protected and has a variety of design features which allow filters to be attached easily and securely.  Take a look at how to measure your PreVent filter.

Other PreVent filter options include the PreVent^® 3-Dimensional Bonnet and Vent Cap with flexible vinyl or elastic edging, PreVent^® Model R with a rigid steel frame.

BUILDINGS magazine selected PreVent® Equipment Protection Filters as an 2010 Money-Saving Product winner. PreVent air intake filter is part of an elite group of 81 products showcased in the magazine’s June 2010 issue.

• Model U1 and Model U2 are constructed with one or two layers of three-dimensional black honeycomb polypropylene electrostatic media, encased in a sewn vinyl edge with single or double stitching and attached with stainless steel grommets. We can also replace the vinyl frame with a sonic welded edge for the Model U1 or Model U2 filter with polypropylene media. The media can be sonic welded in single, double or triple layers with a clean finished edge in place of the vinyl binding.
• Model BHA is constructed with one layer of black PVC-coated polyester high-abrasion media, encased in a sewn vinyl edge with single or double stitching and attached via stainless steel grommets. This media meets NFPA-701 Flame Resistance.
• Independent testing 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, depending on the filter media and number of layers required.
• Both types of black filter media are heat stabilized, and will not shed fibers, absorb moisture or promote bacterial growth.
• The inherent electrostatic charge of our woven polypropylene (BHC) media delivers a higher particle arrestance efficiency and enhanced ability to capture and hold smaller particles. Our heavy-duty high abrasion (BHA) media offers strength, durability and allows us to manufacturer Model BHA in oversized dimensions to fit extra-large equipment such as cooling towers.
• Designed for strength and durability, PreVent filters stand up to extreme outdoor or indoor exposure, corrosive chemicals, high-velocity air flow and industrial cleaning and maintenance.
• Customized to meet any equipment air intake or ventilation inlet and outlet challenge – including those requiring pipe and electrical cut-outs, special shapes and skirting where grommet attachment to the metal enclosure is not possible. Hook/loop or magnets can be added to completely seal air bypass.
• Mounting options for grommets include anchored mount jack nut kits, quick-mount self-tapping slotted screws, a screw-in plastic mounting clip with easy open/close access or the patented MagnaMount^® plastic mounting clip with a fast and easy “earth” magnet attachment. Hook/loop can also be easily attached, with the loop side sewn onto the vinyl edge of the filter and the hook side with adhesive backing attached to the equipment’s housing.
• Oversized flexible vinyl framed filters can be made in one or multiple sections for large equipment. A vinyl center seam is required for dimensions over 60″. Plastic snap mounts are available to overlap multiple filter screens for extra-large air intake applications.
• Standard five-year warranty; extended warranty available upon request.
