85000329 Volvo VNL D12 Twin Cylinder Compressor

This twin cylinder air compressor serves as a critical component within the pneumatic braking system of heavy commercial vehicles. Engineered for high-pressure reliability, it utilizes a water-cooled design to maintain optimal operating temperatures during intensive use, ensuring consistent air supply for the vehicle's braking and pneumatic functions.

This specific model is designed for Volvo VNL trucks equipped with D12 engines. It features a 704cm³ swept volume, a Ø85.00 mm cylinder bore, and a 62 mm stroke. The unit is equipped with an ESS feature and a water-cooled valve plate to enhance longevity under heavy-duty service conditions.

For professional installation, technicians should verify the M26x1,5 air outlet port and the M16x1,5 water inlet/outlet ports. Given the 20.8 KG weight and the through-drive configuration, ensure all mounting points are secure and coolant lines are properly aligned to prevent leaks in the cooling circuit.

Regular inspection of the air unloader port (M12x1) and air inlet (Ø35) is recommended to prevent debris buildup. Maintaining clean coolant flow is essential for the thermal management of this water-cooled unit.
