Challenger's revolutionary technology oil filter assembly is machined from 6061-T6 aircraft billet aluminum. Inside the aluminum housing is a high flow, 22 micron, cleanable woven stainless steel filter element. Large inlet and outlet passages provide for a maximum oil flow rate of twenty two gallons per minute (22 GPM), double the flow of the largest "Throw-Away" oil filters. "It's plain and simple, clean oil preserves piston engine components service life. You'll find that unscheduled removal of engine parts is a thing of the past, and parts that haven't reached their life limit can now be returned to service, saving a bundle on engine overhaul cost", explained Chuck Rocco, Challenger's President. Every year millions of throw-away oil filters and used oil is thrown into land fills. Challenger's cleanable oil filter with up to 100 hours between oil changes will help reduce waste. Challenger Aviation Products also provided FAA-PMA cleanable air filters with K & N filter media. Application Guides are available on our website www.challengeraviation.com.
