1100 250 021 Twin Cylinder, Air Compressor — MERCEDES BENZ

This twin cylinder air compressor is engineered to provide reliable pneumatic pressure for heavy commercial vehicle braking and suspension systems. Designed with a high-strength structure, it features a dual-cylinder configuration with a swept volume of 636cm³ and a stroke of 56 mm. The unit is specifically optimized for water-cooled environments to maintain thermal stability during intensive operation.

1100 250 021 is the OE equivalent of the MERCEDES BENZ 457 130 36 15 SP1, 457 130 48 15 SP1, and 457 130 70 15 SP1 air compressors used in MERCEDES BENZ heavy vehicles, and it is also compatible with WABCO systems such as 912 510 100 0 SP1 and 912 510 103 0 SP1. This component ensures seamless integration with original equipment specifications for optimal system-wide performance.

For workshop technicians, this unit features an M26x1,5 air inlet and outlet port, alongside an M12x1,5 unloader port. The installation requires attention to the water-cooling connection via the M16x1,5 ports to ensure the water-cooled valve plate functions correctly. Regular maintenance of the cooling lines and checking for proper torque on the M26x1,5 threads are essential for long-term service life in heavy-duty truck applications.
