Description

This twin cylinder compressor serves as a critical component in 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. The unit features a swept volume of 704cm³ and is built with high-strength components to withstand demanding service conditions in the transport sector.

This specific model is designed for compatibility with Volvo VNL trucks equipped with D12 engines. The assembly includes an integrated unloader port (M12x1.5) and supports ESS features to ensure precise air pressure regulation within the braking circuit.

Technicians should verify the water inlet and outlet port specifications (M16x1.5) during installation to ensure proper cooling flow. Regular inspection of the M26x1.5 air outlet port and the through drive mechanism is recommended to prevent system pressure drops or leaks in the pneumatic lines.

Consult your authorized distributor for fitment verification.
