1100 045 021 Single Cylinder, Air Compressor — MERCEDES BENZ

This high-strength single cylinder air compressor is engineered to provide consistent pneumatic pressure for heavy commercial vehicle braking systems. Designed as a critical component for air brake reliability, it utilizes a water-cooling mechanism to maintain optimal operating temperatures during intense service cycles. The unit is built with heavy-duty grade materials to withstand the rigorous demands of long-haul transport environments.

1100 045 021 is the OE equivalent of the MERCEDES BENZ 906 130 50 15 SP2, 906 130 54 15 SP1, 906 130 58 15 SP1, WABCO 411 151 009 0 SP1, and WABCO 411 151 012 0 SP1 air compressors used in heavy commercial vehicle applications. This component ensures seamless integration with existing pneumatic architectures provided by leading system makers.

For workshop technicians, this unit offers straightforward installation with a through-drive design. The technical configuration includes an M26x1,5 air inlet port and a Ø30 air outlet port, alongside M14x1,5 ports for water inlet and outlet. Regular maintenance of the cooling system and checking the integrity of the water-cooled valve plate is essential to prevent overheating and ensure long-term functionality in the field.

The precision engineering of this compressor ensures it meets the strict requirements of modern heavy-duty fleets. By maintaining the correct swept volume and pressure stability, it supports the overall efficiency of the vehicle's braking system.
