ASHRAE Pocket Filter:
CJS Pocket Filter is an extended surface, high capacity air filter composed of individual synthetic fiber pockets assembled in a metal support frame. It is designed for use in those areas requiring a higher degree of air cleanliness & where fiber shedding such as Hospitals, Pharmaceutical, Paint Spray Booths, office buildings etc. The pocket filters are not affected by extreme moisture or humid conditions, unlike glass fibers in a wet environment that can lose up to 20% efficiency.
The synthetic Pocket Filter is available in average efficiency ranges of 45-50%, 60-65%, 80-85%, 90-95% and >95% per ASHRAE standard 52.1-1992 atmospheric dust spot test procedures (equal EN779). Operating face velocities up to 750 FPM are available for certain models.
CJS Pocket Filter consists of a series of individual pockets which are bonded to a corrosion-resistant header frame. The potential for air leakage in the header frame of CJS Pocket Filter is prevented through the elimination of teal contact point between individual components. During assembly, all media to metal contact points are glued to assure product integrity during operation.
