PAF 11 Filters — Construction

PAF 11 pleated filters are medium-efficiency, extended surface air filters designed for system applications that demand improved filtration. These filters, with a MERV 11 rating based on ASHRAE Test Standard 52.2-2007, are specifically manufactured to provide enhanced medium-efficiency and non-shedding filtration media. They outperform similar products in both initial and average efficiency, making them effective in single filter applications or as improved pre-filter substitutes for disposables, permanent metal filters, or media pad/frame filters.

Applications - PAF 11 filters provide prefiltration for hospitals, general health care facilities, food processing plants, telecommunications, pharmaceutical and semi-conductor manufacturing, etc.

Media - PAF 11 pleated filters are composed of synthetic media that's made-up of continuous hydrophobic fibers that don't absorb moisture and can withstand turbulent, high velocity conditions. These fibers are thermally-bonded to eliminate the need for chemical binders that could promote microbial growth or generate VOCs. The continous fiber stucture and dual-stage electrostatic enhancement improves overall particle size efficiency and captures an increased amount of smaller particulate than conventional glass media.

Media Support - Continuously bonded to a corrosion resistant, expanded metal grid allowing a 96% open face area.

Pleat Configuration - Formed into aerodynamic, semi-tapered, wedge-shaped pleats expanding its capability to capture contaminants.

Frame - Enclosed in a two-piece, high wet-stength beverage board frame.

Assembly - A fully bonded double-wall frame combines with the integral corner flaps and forms a rugged, durable filter which will not crack, warp or leak under normal operating conditions. To ensure no dirty air bypass, the media pack is securely bonded to the periphery of the frame with solvent-free, water-based glue. In 4" models, accurate pleat alignment is maintained by die-cut pleat spacers on the upstream side.

Classification - PAF 11 filters are classified per UL Standard 900 for flammability, ensuring a high level of safety.
