2500 250 001 Compatible Single Cylinder Compressor

What does a single cylinder compressor do?

This single cylinder air brake compressor is a piston-type unit designed to provide the necessary compressed air for the braking systems of heavy commercial vehicles. By utilizing a high-strength component design, it ensures reliable pressure delivery even under demanding operating conditions. This unit is specifically engineered to integrate into the engine cooling circuit to prevent overheating during sustained use.

Vehicle and engine compatibility

The compressor is compatible with various heavy commercial vehicles, including KamAZ models 4308, 5308, 65115, and 6520, as well as Paz 3204 and 3237. It is also fitted to Ford Trucks Cargo, Volkswagen Constellation, and Dongfeng vehicles like the Captain and Duolika. This component is designed to work seamlessly with Cummins ISBe and ISLe engines, ensuring optimal system performance.

Installation and maintenance guidance

For installation and maintenance, technicians should verify the water inlet port (M16x1,5) and outlet port (M16x1,5) connections are secure to prevent leaks. The unit features an M26x1,5 air inlet port and an M22x1,5 air outlet port. Regular inspection of the water-cooled valve plate and unloader port (M10x1) is recommended to maintain peak efficiency.

Selection and performance tips

When replacing a compressor, ensure the through drive mechanism is correctly aligned with the engine drive to prevent premature wear of the internal piston and ring assemblies.
