This single cylinder compressor is a critical component within the pneumatic braking system of heavy commercial vehicles. Designed to withstand demanding operating conditions, it provides the necessary compressed air for reliable braking performance and system actuation. The unit features a water-cooled design to maintain optimal thermal stability during continuous operation.

Compatible Volvo FH models

This component is specifically engineered for Volvo FH models including the 400, 420, 440, 460, 480, 500, 520, and 540 series. It is built to match the technical requirements of these heavy-duty engines, ensuring seamless integration within the vehicle's air management architecture.

Installation and technical specifications

The assembly features an Ø85.00 mm cylinder bore and a 56 mm stroke, delivering a swept volume of 318cm³. Installation requires careful attention to the water inlet and outlet ports (M16x1,5) and the air outlet connection (M26x1,5). Technicians should verify the through drive type and unloader port (M12x1,5) before installation to ensure correct fitment.
