Our HL Series bags are extended life fillter bags that have up to 3 times the dirt holding capacity of standard filter bags at the equivalent micron ratings. These multi layer bags are constructed with 2 gradient layers of polypropylene felt separated by a transfer/caking filter layer. The initial layer is for pre-filtration and the final layer is an anti media migration layer. HL Series bags have a molded flange or stainless steel ring to ensure a positive seal with the filter housing. 95% efficiency ratings at 20, 40, 70, and 125 microns are equivalent to industry grades 1/2, 1, 20, and 50 microns respectively.
Choose from the drop down menus, either Poly flange for Rosedale housings, or Ring style bags to fit in any manufacturers' filter housings. RPE/RPO top bags offer the best bag-to-housing seal in today's marketplace. Micron ratings are performance at 95% efficiency. Size tab reflects industry standard bag size number.
