TEMPEST® AAD9-18-1 Filter Element Tempest AAD9-18-1 is pneumatic filter used in the 1J7-1 filter assembly. The air filter alternates with Airborne D9-18-1, Rapco RAD9-18-1 and Cessna C294502-0201 pneumatic filters. Clean filters are essential for pneumatic systems to operate efficiently. The pneumatic filters are an inexpensive way to prevent particles from damaging the critical components. Tempest manufactures a complete line of FAA-PMA approved aviation pneumatic filters. Tempest pneumatic filters use .3-micron filtration elements which offer excellent protection against outside contaminants, such as dust and other cabin pollutants. Using Tempest pneumatic filters and replacing them at proper intervals will keep the system clean and improve pneumatic system performance.
