| ELIMINATES PRODUCT FAILURES The Tri-Stop panel and continuous link filters are made tough. Three layers of polyester media securely heat sealed around a 9 gauge internal support grid. No chipboard frame to collapse. No falling out of frames or side access tracks.
ELIMINATES UNFILTERED AIR
The three layers of media extend past the four perimeter sides of the Tri-Stop panel. These self-sealing edges lock the filter in place and eliminate any unfiltered air from going around the filter. Dirt goes into the filter- not downstream. Tri-Stop links are continuous panels. No space between - no dirt passing between. |
