85013935 VOLVO Twin Cylinder, Air Compressor

The 85013935 is a critical component within the pneumatic system of heavy commercial vehicles, specifically designed to provide consistent air pressure through its dual-cylinder architecture. This twin cylinder air compressor is engineered with high-strength components to withstand rigorous industrial environments. Its primary function is to maintain the necessary air volume for braking and suspension systems, ensuring the vehicle remains operational under heavy-duty loads.

85013935 is the OE-equivalent of the VOLVO 85013935 Twin Cylinder, Air Compressor used in VOLVO heavy commercial vehicles. This unit features a precise Ø85.00 cylinder bore and a 56 mm stroke to achieve a swept volume of 636cm³. The integration of an M26x1,5 air outlet port and M16x1,5 water ports ensures optimal performance and thermal regulation during long-haul operations.

For workshop technicians performing maintenance or repairs, this part offers seamless assembly-ease due to its standardized port dimensions and through-drive design. It is essential to verify the compatibility of the M16x1,5 water inlet and outlet ports with the existing cooling lines to prevent overheating. Regular inspection of the air unloader port and ensuring the ESS feature functionality are recommended during routine service intervals to maintain system integrity.

This component is vital for maintaining the pneumatic stability required in heavy-duty truck applications. By providing a reliable source of compressed air, it supports the overall efficiency of the vehicle's air brake systems.
