Purolator's PAF 11 filters are medium-efficiency, extended surface, pleated air filters. Specifically manufactured for system applications requiring improved medium-efficiency, non-shedding filtration media. Outperforms similar products with respect to initial efficiency, and average efficiency providing optimum filter service life. Effective in single filter applications or as improved pre-filter substitutes for disposables, permanent metal filters or media pad/frame filters.

Features & Benefits

• Synthetic media made up of continuous hydrophobic fibers which do not absorb moisture and can withstand turbulent, high velocity conditions
• Fibers are needled to eliminate the need for chemical binders that could promote microbial growth or generate VOCs
• Improved overall particle size efficiency due to continuous fiber structure and dual-stage electrostatic enhancement which captures an increased amount of smaller particulate than conventional glass media
• Enclosed in a two-piece, high wet-strength beverage board frame
• A fully bonded double-wall frame combines with the integral corner flaps and forms a rugged, durable filter which will not rack, 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
