Pall Aerospace (Booth 4920) has selected South Carolina-based aviation parts supplier AeroProducts as the distributor for its line of PUREair engine inlet dry barrier filters. The dry filters eliminate all the problems associated with the traditional oil-wetted filter, which generally entail a long drying period after washing and require re-oiling, according to the manufacturer.
The dry barrier media filters can be cleaned with a garden hose or by pressurized air and reinstalled almost immediately, with no oily hazardous waste water to dispose. Pall noted its dry filters are up to 40 percent lighter than their oil counterparts. The product is available for use with an FAA-PMA on the Bell 206L/407 and Airbus AS350 helicopters, as well as UH-1H Huey fire-fighting helicopters.
