What does a twin cylinder compressor do?

This twin cylinder compressor serves as a critical component within the pneumatic braking system, ensuring consistent air pressure for heavy commercial vehicle safety. Built with high-strength components, it maintains reliable air delivery under demanding operating conditions to support the braking and suspension systems.

Compatible vehicles and engines

Specifically designed for Volvo FH12 trucks equipped with D12A engines, this unit ensures precise pneumatic performance. The design incorporates a water-cooled valve plate and an ESS feature to optimize thermal management during operation. It is compatible with Volvo OE specifications for seamless integration.

Installation and maintenance

Technicians should note the specific port requirements during installation: the air inlet port is Ø29, the air outlet port is M26x1.5, and the air unloader port is M22x1.5. Proper connection of the M16x1.5 water inlet and outlet ports is essential to maintain the cooling efficiency required for heavy-duty service.
