2900 030 001 Compressor Single Cylinder — Cummins

What does a single cylinder compressor do?

This single cylinder air brake compressor is a vital component for the pneumatic system of heavy commercial vehicles. It functions by compressing intake air to provide the necessary pressure for the braking system and other pneumatic actuators. Designed with a water-cooled mechanism, this unit maintains optimal operating temperatures even during sustained heavy-duty use, ensuring long-term reliability and preventing overheating.

Vehicle and engine compatibility

This compressor is specifically engineered to be compatible with Cummins ISBe and ISLe engines. It is also fitted to various heavy vehicles including KamAZ models (4308, 5308, 65115, 6520), Dongfeng (Duolika, Captain, Tianjin, Kinland), Yutong (ZK6118, ZK6125), Zhongtong (LCK6118), and Volkswagen Constellation. It also serves Paz, Liaz, Nefaz, and Iveco Bus Metro vehicles.

Technical specifications and installation

Technical specifications include a Ø80.00 cylinder bore and a 45mm stroke, providing a swept volume of 225cm³. The unit features an M26x1,5 air inlet port and an M22x1,5 air outlet port. For installation, ensure the water inlet and outlet ports (M16x1,5) are properly connected to the engine cooling circuit to maintain the water-cooled functionality.

Maintenance and selection guidance

To ensure correct fitment, technicians should verify the engine type and existing port configurations before replacement. Maintaining clean air intake and proper coolant flow through the M16x1,5 ports will extend the service life of this component. Consult your authorized distributor.
