Description
Full Product Description Permalast® is made from extra-heavyweight polyester fibers bonded into air filter media in the form of a high-loft interlocking mat which is extremely rigid. This rigidity eliminates the need for external support, which means there is no requirement for a holding frame with wire backing to retain the pads in service. Permalast® media is also very flexible, which allows for easy installation in tight spaces. It can be twisted, bent or flexed in any way necessary to make it fit and is capable of springing back to its original shape. Permalast® filter media is ideally suited for use in heavy-duty installations, such as outdoor locations or where high concentrations of dust, lint, hair, leaves or other large particulates are present. The polyester fibers bonded with a polyvinyl acetate binder provide high compression strength and allow the filters to be washed or vacuum-cleaned. There is no need to order special-sized disposable panel filters, as Permalast® media can be simply cut to the desired size with scissors, a utility knife or a paper cutter, making installation quick and easy
Permalast® filter media is available as: -Pre-cut pads of multiple sizes (from 14 x 25 and 16 x 20 to 20 x 25 in) -30-in long, 25- and 50-in wide rolls that can be cut into pads of optional sizes Markets: Commercial and Industrial HVAC Process Air Filtration Applications: Air handling systems Prefilters Benefits Rigid, self-supporting but flexible at the same time Can be washed or vacuum-cleaned Can be cut to the desired size with scissors, a utility knife or a paper cutter Suited for use in heavy-duty installations such as outdoor locations or where heavy concentrations of dust, lint, hair, leaves, or other large particulates are present Features Nominal thickness (in.): ½, 1, 2 Rated air velocity (fpm): 300 Initial resistances (in.w.g.): 0.5, 0.9, 0.16 Final resistances (in.w.g.): 0.5, 1.0, 1.0 Material of construction: extra-heavy weight polyester fibers, polyvinyl acetate binder
