Description

The heavy-duty twin cylinder air compressor is a critical component for maintaining stable pneumatic pressure within the vehicle's braking and suspension systems. Designed for high-strength performance, this part ensures consistent air delivery through its optimized cylinder bore and stroke mechanics. The integrated water-cooling system and high-strength components make it suitable for the most demanding heavy commercial vehicle environments.

394941 is the OE-equivalent twin cylinder, air compressor used in SCANIA systems. This component is engineered to meet strict technical specifications, ensuring seamless integration with the vehicle's original air management hardware. It is specifically designed to maintain the high-pressure requirements necessary for heavy commercial vehicle operations.

Workshop technicians can rely on the precision of this unit during routine maintenance or full system overhauls. The unit features an M12x1,5 air unloader port and M18x1,5 water inlet/outlet ports to ensure secure and leak-free assembly. Regular checks of the water cooling connections and the water-cooled valve plate performance are recommended to ensure long-term operational stability in the field.

With a weight of 22,2 KG and a robust construction, this compressor provides reliable service in the air brake systems of heavy commercial vehicles. The inclusion of the ESS feature and a dedicated water-cooled valve plate ensures that the thermal management remains efficient even under high load conditions.
