20547525 VOLVO Twin Cylinder, Air Compressor

This twin cylinder air compressor is engineered to provide consistent and reliable pneumatic pressure within the heavy commercial vehicle braking system. Designed as a high-strength component, it utilizes a water-cooled architecture to maintain optimal operating temperatures during intensive service cycles. The precision-engineered two-cylinder design ensures stable air production for demanding transport operations.

20547525 is the OE-equivalent VOLVO air compressor used in the VOLVO FH 12/340. This unit features a cylinder bore of Ø85.00 mm and a stroke of 62 mm, delivering a swept volume of 704cm³. It is specifically designed for compatibility with the D12 engine configurations often found in these heavy-duty vehicle systems.

The installation process requires attention to the water cooling connections and air ports to ensure maximum efficiency. The unit features an M26x1,5 air outlet port and an M12x1 unloader port. Workshop technicians should verify the water inlet and outlet ports (M16x1,5) and ensure the through-drive is properly aligned during assembly to prevent mechanical wear and maintain optimal system pressure.

Maintaining regular checks on the water-cooled valve plate and ensuring clean air inlet paths will extend the service life of this component. This part is essential for maintaining high-performance standards in heavy truck braking systems where durability is paramount.
