1100 020 021 MERCEDES BENZ Twin Cylinder, Air Compressor

This high-strength component is designed to provide reliable air compression for heavy commercial vehicle pneumatic systems. Featuring a dual-cylinder configuration and water-cooling capabilities, it ensures stable performance under demanding operational cycles. The design integrates a specialized water-cooled valve plate to maintain optimal thermal management during high-load transport tasks.

1100 020 021 is the OE equivalent of the MERCEDES BENZ 457.130.2415 SP2 and 457.130.4415 SP2 Twin Cylinder, Air Compressor used in MERCEDES BENZ heavy commercial vehicles. This part is also fully compatible with WABCO systems including part numbers 457 130 2415 SP2 and 457 130 4415 SP2. The precision-engineered components ensure seamless integration with existing braking and pneumatic architectures.

Workshop technicians should verify the water inlet and outlet port specifications (M16x1,5) during installation to ensure proper cooling-circuit connectivity. Given the through-drive design and the specific air unloader port (M12x1,5), precise assembly is required to maintain system pressure integrity. Regular maintenance of the cooling-water connections is recommended to prevent overheating of the cylinder assembly.

This air compressor is engineered for durability in the heavy-duty sector, specifically for truck and bus applications where consistent air pressure is critical for safety. The robust construction helps mitigate vibration and thermal stress during long-haul operations.
