Ashrae-ULPA Efficiency Fiberglass Filter Paper

♦ Detaileddescription
Itiscomprised primarily of glass fiber produced by a wet laid process which is similar to that used in the production of paper. Our offerings rang from various ASHRAE grades (F6-F9), HEPA grades (H10-H14) to ULPA grades (U15-U16) with exceptional dust holding performance and provide with the highest available efficiency at a minimal resistance to air flow. It's available in a laminated form to meet special air filtration requirements.
