Purolator Hi-E Collapsible Pleat

Purolator’s Hi-E Series 8", 12", and 24" filters are deep pleated, medium, and high efficiency pre-formed cartridge type air filters. Each air filter cartridge is comprised of deep pleated reinforced nonwoven cotton/synthetic blended or ultra-fine micro glass media with a spun-bonded nylon backing which is completely pre-formed and bonded on the top and bottom to 60-point chipboard panels.

In a typical application, the cartridge filter element is inserted into a permanently installed filter assembly, consisting of a filter holding frame, sealer ring, wire retainer, and filter clips.
