541 130 27 19 S1 Mercedes Benz ACTROS MP2 MP3 Air Compressor

This single cylinder air compressor is engineered to provide reliable pneumatic pressure within the vehicle's air brake system. Designed for heavy commercial vehicle applications, it features a robust construction to withstand continuous duty cycles. The unit utilizes a water-cooled mechanism to maintain optimal operating temperatures, ensuring long-term stability and preventing thermal degradation during intensive use in heavy-duty transport environments.

541 130 27 19 S1 is the OE-equivalent single cylinder air compressor used in the Mercedes Benz ACTROS MP2 / MP3 4144. This component is essential for maintaining the pneumatic integrity of the braking and suspension systems. It features a specific configuration with a Ø100.00 cylinder bore, a 48 mm stroke, and an M26x1,5 air inlet and outlet port to ensure seamless integration with existing vehicle architecture.

For workshop technicians, this unit offers straightforward installation due to its standardized through-drive and specific port dimensions, including an M12x1 air unloader port. The water inlet and outlet ports (M14x1,5) must be connected to the cooling circuit following standard heavy commercial vehicle service protocols. Regular inspection of the M26x1,5 ports and cooling efficiency is recommended to maintain optimal system pressure and prevent downtime.

Maintaining precise pressure-to-volume ratios is vital for the vehicle's safety systems. This compressor is built with high-strength components to ensure that the swept volume of 377cm³ remains consistent under load. Technicians should verify all port seals and connections during every scheduled maintenance interval to ensure the longevity of the pneumatic system.
