70330094 SP1 VOLVO (7600 750 002, 470775, 478777 with gear) Twin Cylinder Air Compressor

The technical function of this air compressor is to provide consistent pneumatic pressure within the vehicle's air brake system. Designed as a twin cylinder unit, it ensures high-strength component performance and long-term durability under demanding heavy commercial vehicle operations. The unit is engineered to maintain stable air output through its precision-engineered cylinder-bore and stroke mechanisms.

This product is the OE-equivalent of the VOLVO 70330094 SP1 twin cylinder air compressor used in VOLVO heavy commercial vehicles. It is compatible with part numbers 7600 750 002, 470775, and 478777 (with gear). The assembly is specifically designed for high-duty cycles and maintains seamless integration with existing pneumatic systems.

Workshop technicians should note that this water-cooled unit features an air inlet port of Ø29 and an air unloader port of M22x1,5. For proper installation, ensure the water inlet and outlet ports (M16x1,5) are correctly connected to the cooling circuit to prevent overheating. Regular maintenance of the water-cooled valve plate and checking the M26x1,5 outlet connection is recommended to ensure optimal system pressure.

Detailed technical specifications include a swept volume of 608cm³ and a dual-cylinder configuration. This part provides a reliable solution for maintaining the air braking systems in professional fleet management and heavy-duty service environments.
