2900 090 001 Compatible Single Cylinder Air Compressor

What does a single cylinder air compressor do?

This single cylinder air brake compressor is a piston-type component designed to produce the compressed air required by the braking system in heavy commercial vehicles. By utilizing a single-piston, single-cylinder housing structure, it ensures efficient air generation for vehicles operating under demanding conditions. It functions as the primary link in the pneumatic circuit, sending pressurized air to the processing unit and tanks.

Vehicle compatibility and design

This specific model is compatible with International vehicles and is designed to meet the requirements of Knorr-Bremse systems. The unit features a through drive design and is specifically engineered for water-cooled applications, making it well-suited for long-haul or heavy-load operations where temperature regulation is vital to maintain consistent pressure.

Installation and maintenance

To ensure optimal performance, technicians should verify that the water inlet and outlet ports (1,2” - 14 UNF) are free of debris during installation. Regular inspection of the Ø88.00 mm bore and the 37 mm stroke components is recommended to prevent pressure drops. Consult your authorized distributor for fitment confirmation.

Troubleshooting and service

Maintaining proper cooling flow through the water ports is essential to prevent overheating during sustained engine operation. If brake response times decrease, an inspection of the compressor's internal piston assembly may be necessary to ensure continuous system integrity.
