1100 040 021 Single Cylinder Air Compressor

The Single Cylinder Air Compressor is a critical component designed to provide consistent pneumatic pressure within the vehicle's braking and suspension systems. This specific model is engineered to meet the rigorous demands of heavy commercial vehicle environments, ensuring operational stability and long-term durability.

The 1100 040 021 is the OE equivalent of the Mercedes-Benz 9061300715SP1, 9061301115SP1, 9061302815SP1, 9061304115SP1, 9061305015SP1, and WABCO 4111510030SP1 used in various heavy-duty applications. This unit features a single cylinder with a Ø85.00 mm bore and a 42 mm stroke, optimized for high-strength performance in demanding environments.

Designed for technical precision, this compressor includes a water-cooled mechanism with M26x1,5 air inlet and M30 air outlet ports. The water inlet and outlet ports are sized at M14x1,5 to ensure efficient thermal regulation during operation. It is essential for workshop technicians to verify port compatibility and ensure the through-drive mechanism is correctly aligned during installation.

Regular maintenance of the air delivery system helps prevent pressure drops in the braking circuit. Technicians should check the water cooling ports and the condition of the valve plate to ensure optimal performance of the pneumatic system.
