1784109 SCANIA G440 Twin Cylinder, Air Compressor

This twin cylinder air compressor is engineered to provide consistent pneumatic pressure within the braking and air systems of heavy commercial vehicles. Designed for high-duty performance, the unit features a robust construction to withstand demanding operational environments. Its specialized design ensures optimal air flow and system stability during long-haul transport operations.

Specifically developed for the SCANIA G440, this component serves as a critical replacement part. 1784109 is the OE-equivalent of the SCANIA 1784109 twin cylinder, air compressor used in the SCANIA G440. This part meets exact technical specifications including a 608cm³ swept volume and a dedicated water-cooling system to maintain thermal stability during intense usage.

For workshop technicians, installation requires attention to the specific port dimensions: the air inlet utilizes an M26x1,5 connection, while the outlet and unloader ports use M22x1,5. The unit is water-cooled (W) with M18x1,5 inlet/outlet ports. Regular maintenance of the cooling lines and checking the through-drive integrity is recommended to ensure continuous service life in fleet operations.

Technical specifications include a 50 mm stroke and a dual-cylinder configuration to provide stable output. The inclusion of the ESS feature and specialized water-cooled valve plate ensures that the compressor maintains efficiency even under high thermal loads typical of heavy-duty truck applications.
