2500 280 001 Air Compressor for Cummins engines

What does a twin cylinder compressor do?

This twin cylinder air compressor is an engine-driven unit designed to meet the high air pressure demands of heavy commercial vehicle braking systems. By utilizing two piston-cylinder assemblies, this component delivers higher air output compared to single-cylinder models, ensuring reservoirs are filled quickly and efficiently. It is constructed with high-strength components to withstand the intense thermal and mechanical stresses of continuous operation.

Vehicle and engine compatibility

This unit is compatible with several heavy vehicles, including Iveco Bus Metro, Yutong ZK6118 and ZK6125, and KamAZ 65115, 6520, 4308, and 5308 models. It also fits Ford Trucks Cargo, Volkswagen Constellation, Dongfeng Tianjin and Captain, as well as KamAZ, Paz, Liaz, Nefaz, and Zhongtong vehicles equipped with ISLe or ISBe engines. It is also compatible with Cummins engines.

Technical specifications and installation

Technicians should note the specific technical configuration: this model features an M26x1.5 air inlet and outlet port, along with M16x1.5 water inlet and outlet ports. The water-cooled design helps maintain optimal operating temperatures during heavy-duty service cycles. Regular inspection of the cooling lines and port integrity is recommended to ensure system stability.

Maintenance and troubleshooting

To ensure proper function, check that the water-cooled valve plate is seated correctly and that there are no leaks at the M26x1.5 ports during installation.
