The FAA Filters PL Series Cellulose Pleated Air Filter is available in multiple micron ratings from 1/2 to 40 micron nominal. It is designed and built to eliminated contaminated fluid bypass, with cartridge sealing integrity provided by the heavy gauge metal end caps. Many gasket, bonding, and metal component materials are available for specific fluid compatibility requirements. The PL Series filter can be broken out into three application groups based on the filtration grade:
