541 130 27 19 S1 MERCEDES BENZ ACTROS 3343 Air Compressor

This high-strength single cylinder air compressor is engineered to provide consistent pneumatic pressure within the heavy commercial vehicle braking system. Designed for heavy-duty operation, the component ensures stable air delivery through a specialized water-cooling architecture, maintaining optimal thermal stability during intensive driving cycles.

541 130 27 19 S1 is the OE-equivalent of the MERCEDES BENZ 541 130 27 19 S1 single cylinder air compressor used in the MERCEDES BENZ ACTROS 3343. This unit features a cylinder bore of Ø100.00 and a stroke of 48 mm, providing a swept volume of 377cm³. It is designed to meet the rigorous demands of professional heavy-duty transport environments.

Workshop technicians should note the specific port configurations for seamless installation. The unit utilizes an M26x1,5 air inlet and outlet port, alongside an M12x1 air unloader port. The water cooling system is integrated via M14x1,5 inlet and outlet ports. Regular inspection of the water-cooled interfaces and ensuring the through-drive alignment is critical for maintaining system longevity and preventing pneumatic leaks in the brake circuit.
