70330098 VOLVO B12 Twin Cylinder, Air Compressor

The heavy duty Twin Cylinder, Air Compressor is a vital component for maintaining consistent pneumatic pressure within the vehicle's braking and suspension systems. Designed with high-strength components, this unit ensures reliable air delivery even under demanding operational conditions. Its dual-cylinder architecture provides the necessary structural integrity and volume to meet the requirements of heavy commercial vehicle air systems.

70330098 is the OE-equivalent Twin Cylinder, Air Compressor used in VOLVO B12, B12B, B12R, B7L, FH12, FH16, FL12, FM12, FM7, and NH12 models. This component is engineered to meet strict technical standards for seamless integration with existing Volvo engine architectures. It maintains precise fitment for all specified heavy commercial vehicle applications.

For workshop technicians, this unit features a Ø88.00 cylinder bore and a 50 mm stroke, with a water-cooled design (W) to ensure thermal stability. The assembly includes an M26x1,5 air outlet port and an M22x1,5 air unloader port. Regular inspection of the water inlet (M16x1,5) and outlet ports is recommended during routine service intervals to maintain optimal cooling efficiency and system performance.

Proper installation of this water-cooled compressor is essential for long-term reliability of the air brake system. The inclusion of the ESS feature and a water-cooled valve plate provides an added layer of protection against overheating during high-load cycles.
