Building on WABCO's reputation for robust and state of the art air processing technology, the new Compact APU from WABCO meets today's market need for a small, totally integrated one-body APU solution offering multiple functionality and high performance. The WABCO standard air dryer and multi circuit protection valve are combined in a single, compact body that requires less space while covering the main functions of the Air Processing Unit (APU).

Additionally, the Compact APU features an innovative upstream oil pre-separation filter unique to WABCO. Making use of centrifugal forces and plumbing effects, it filters out the bigger oil and water droplets before compressed air reaches the air drying cartridge, improving its efficiency.
