70330056 SP1 VOLVO Twin Cylinder, Air Compressor

The high-strength twin cylinder air compressor is engineered to provide consistent pneumatic pressure within the heavy-duty braking and pneumatic systems of heavy commercial vehicles. Designed with a robust architecture, this component features a dual-cylinder configuration that ensures reliable air production under high-load conditions, making it a critical part for maintaining system stability.

70330056 SP1 is the OE-equivalent of the VOLVO 70330056 SP1 air compressor used in the VOLVO heavy commercial vehicle fleet. This part is specifically designed to meet strict technical requirements, featuring a Ø85.00 mm cylinder bore and a 62 mm stroke to achieve a swept volume of 704cm³. Its precise dimensions and specialized ports ensure seamless integration into existing vehicle architectures.

For workshop technicians and fleet managers, installation requires attention to the water-cooling connections. This unit utilizes M16x1,5 ports for both water inlet and outlet to manage thermal regulation effectively. The assembly includes an M26x1,5 air outlet port and an M12x1,5 air unloader port. Regular maintenance of the cooling circuit and inspection of the through-drive components are recommended to ensure optimal service life and prevent system downtime during heavy-duty operations.
