For over 25 years, Walker Engineering made the best Air Oil Separator money could buy. Airwolf has acquired all the rights and STCs from Walker Engineering.
The Walker AirSep uses a large enough air volume (hence its larger size) and a tiny amount of vacuum pump discharge air, to help condense the oil inside the AirSep, and to overcome crankcase pressure to return collected oil to the engine while the engine is running. Competitive systems are only gravity flow so no oil returns into the engine until the engine is completely shut off. Walker AirSeps are complete with everything you need to install it onto the airplane. One system is large enough to clean both the engine breather oil and wet vacuum pumps discharge.
