A4701303715 Mercedes-Benz AROC S OM 470 LA Compressor

What does a twin cylinder compressor do?

This twin cylinder compressor serves as a critical component within the air brake system of heavy commercial vehicles, generating the necessary compressed air pressure for reliable braking performance. Designed to meet EURO 6 emission standards, this unit utilizes two piston-cylinder assemblies to deliver high air output, making it ideal for demanding applications where rapid pressure buildup is essential.

Compatible vehicles and engines

This specific model is engineered for use in Mercedes-Benz AROC S trucks, specifically the 1836 AK and 1836 A variants equipped with OM 470 LA engines. It features a water-cooled design with an M18x1.5 water inlet and outlet port, ensuring stable thermal management during continuous operation in heavy-duty service.

Installation and maintenance

When performing replacement, technicians should verify that the drive type and mounting interface match the original unit exactly. This compressor features a through drive configuration and includes an ESS feature to support system efficiency. Ensure that the air inlet port (Ø34.50) and air outlet port (M26x1.5) are checked for proper sealing during installation to maintain system integrity.

Selection and service guidance

To maximize service life, regular inspection of the cooling system and intake filters is recommended. Proper maintenance of the air dryer and engine oil supply helps prevent premature wear of the internal valve plate and piston assemblies.
