20773343 SP1 Compressor Compatible with Volvo VNL D12

What does a twin cylinder compressor do?

This twin cylinder compressor serves as a critical component within the air brake system of heavy commercial vehicles. Designed to provide consistent pneumatic pressure, it utilizes a water-cooled mechanism to manage thermal loads during operation. The unit features a Ø85.00 mm cylinder bore and a 62 mm stroke, contributing to a swept volume of 704cm³ for efficient air production.

Vehicle and engine compatibility

This specific model is engineered for use in Volvo VNL trucks equipped with D12 engines. It is compatible with the heavy-duty requirements of the vehicle's pneumatic system, ensuring that air pressure is maintained for reliable braking performance. The unit includes an integrated ESS feature and a water-cooled valve plate to support long-term durability in demanding environments.

Installation and technical specifications

For proper installation, technicians should verify the water inlet and outlet port specifications (M16x1,5) and the air outlet port (M26x1,5). Ensuring that the through-drive and unloader port (M16x1,5) match the existing engine configuration is essential for successful integration into the vehicle's air system.

Maintenance guidance

Regular inspection of the cooling lines and port connections is recommended to prevent pressure drops or overheating. Matching this component to the existing engine specifications ensures optimal system interplay and prevents unnecessary wear on other pneumatic components.
