1300 090 009 KNORR-BREMSE Twin Cylinder, Air Compressor

The technical function of this twin cylinder air compressor is to provide a constant and reliable supply of compressed air to the pneumatic braking and suspension systems of heavy commercial vehicles. Engineered with high-strength components, it manages high pressure through a dual-cylinder architecture designed for continuous operation in heavy-duty cycles.

1300 090 009 is the OE-equivalent of the KNORR-BREMSE II38845F, II39080F, K01268X00, LK4921, and LP4996 air compressors used in VOLVO 7033 own most models. This unit is specifically compatible with KNORR-BREMSE systems and VOLVO heavy commercial vehicles requiring precise air management. It features a water-cooled design with a Ø88.00 mm bore and a 5{mm} stroke to maintain thermal stability during intense operation.

Workshop technicians should note that this unit utilizes a water-cooling system with M16x1,5 inlet and outlet ports to prevent overheating. During installation, ensure the M26x1,5 air outlet and M22x1,5 unloader port are properly aligned with the vehicle's pneumatic lines. Regular maintenance of the cooling circuit and checking the through-drive integrity is essential for maintaining optimal service intervals in the workshop.

For optimal reliability, this component is built to handle the thermal stresses of high-pressure air compression. The integration of the ESS feature ensures the system remains stable under fluctuating load conditions common in long-haul transportation.
