II34840 KNORR-BREMSE Twin Cylinder, Air Compressor

The heavy-duty Twin Cylinder, Air Compressor is a critical component designed to provide reliable pneumatic pressure within the vehicle's braking system. Engineered with high-strength components, this unit ensures consistent air supply and long-term durability under demanding operational conditions. Its water-cooled design helps maintain optimal thermal stability during continuous use.

II34840 is the OE-equivalent of the KNORR-BREMSE II34840 Twin Cylinder, Air Compressor used in heavy commercial vehicle systems. This precision-engineered part is fully compatible with KNORR-BREMSE systems, ensuring seamless integration and maintaining the required pneumatic performance for heavy commercial vehicles.

The installation process requires careful attention to the water inlet and outlet ports (M16x1,5) to ensure effective cooling. Workshop technicians should verify the integrity of the M26x1,5 air ports during assembly to prevent leaks. Regular maintenance of the cooling lines and checking for any signs of wear in the cylinder mechanism is recommended to ensure sustained service life and system reliability.

With a specialized cylinder bore of Ø75.00 and a 50 mm stroke, this compressor delivers a swept volume of 440cm³. This specific configuration is optimized for high-output air compression requirements in professional workshop environments.
