1100 045 021 MERCEDES BENZ Compatible Air Compressor

This single-cylinder air compressor is a critical component for maintaining optimal pneumatic pressure within the heavy commercial vehicle braking system. Engineered with high-strength components, the unit features a cylinder bore of Ø85.00 mm and a stroke of 42 mm to deliver consistent air volume. The integrated water-cooling system and specific port dimensions ensure the unit operates within safe thermal limits during intensive driving cycles.

1100 045 021 is the OE-equivalent of the MERCEDES BENZ 906 130 50 15 SP2, 906 130 54 15 SP1, and 906 130 58 15 SP1 air compressor used in MERCEDES BENZ heavy commercial vehicles. It is also fully compatible with WABCO systems such as the 411 151 009 0 SP1 and 411 151 012 0 SP1. This part is specifically designed to meet the rigorous requirements of professional workshop technicians and fleet managers.

For workshop technicians, this component offers straightforward installation thanks to its standardized M26x1,5 air inlet and M14x1,5 water inlet/outlet ports. Proper maintenance of the cooling circuit and regular inspection of the air outlet port (Ø30) are essential to ensure long-term reliability. Regular checks of the through-drive mechanism and water-cooled valve plate performance are recommended during routine service intervals to prevent system pressure drops.
