Permatron PreVENT Media Flexible Frame Air Intake Filter Model U
Permatron developed and patented Prevent® Equipment Protection Filters as a primary pre-filtration defense to help prevent the damage and extensive maintenance that large volumes of debris can cause. Custom designed and manufactured to fit any sized air intake, the PreVent® Model U1 and U2 filter is constructed with 1 or 2 layers of three-dimensional black polypropylene electrostatic media and encased in a 1-1/4″ sewn vinyl edge with single or double stitching. We also offer a sonic sewn 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
The woven black polypropylene media is heat stabilized, and will not shed fibers, absorb moisture or promote bacterial growth. The additional benefit of the media’s inherent electrostatic charge is higher particle arrestance efficiency and enhanced ability to capture and hold smaller particles. Designed for strength and durability, the PreVent® equipment protection filter is UV protected, and stands up to extreme outdoor or indoor exposure, corrosive chemicals, high velocity air flow, as well as industrial cleaning and maintenance handling.
Custom made to the exact perimeter of the air intake, PreVent® has a variety of design features which allow filters to be attached easily and securely. Model U filter can be attached via 3/8″ ID and 13/16″ OD stainless steel grommets. Mounting options include anchored mount jack nut kits, quick mount self tapping slotted screws, or a plastic mounting kit with easy open/close access. Model U can also be easily attached with hook/loop. The loop side is sews onto the vinyl edge of the filter and the hook side with adhesive backing is attached to the equipment’s housing.
Model U can also be made in custom shapes to meet application specs. Elastic edging, pull tabs and drawstrings can be added for easy access or velcro closures for wrap around style filters. Additional media (non-woven polyester or foam) can be added to the filter configurations to increase arrestance efficiencies. See PreVent Bonnet Filters page for additional styles.
Oversized filters, with both dimensions over 60″, must use BHA media. Plastic snaps mounts are available to overlap multiple filter screens for extra large air intake
