What does a twin cylinder compressor do?

This twin cylinder compressor serves as a critical component within the air brake system of heavy commercial vehicles, generating the compressed air required for braking and pneumatic operations. By utilizing two piston-cylinder assemblies, this unit provides higher air output compared to single-cylinder variants, ensuring faster reservoir replenishment under heavy demand.

Compatibility with Volvo FL12

This specific model is designed for Volvo FL12 vehicles equipped with TD123 engines. It is engineered to meet the rigorous requirements of the vehicle's pneumatic system, providing consistent pressure through its high-strength components. It is also compatible with other heavy-duty applications requiring high-output air delivery.

Technical specifications and cooling

The unit features a water-cooled design to maintain thermal stability during sustained operation. Technical specifications include a Ø75.00 mm cylinder bore, a 50 mm stroke, and M26x1.5 air inlet and outlet ports. The assembly includes a water-cooled valve plate and utilizes an M16x1.5 connection for the water circuit to prevent overheating during heavy-duty service.

Installation and maintenance guidance

To ensure correct installation, technicians should verify that the drive type and mounting interface match the removed unit exactly. Proper maintenance of the cooling circuit and regular inspection of the ports is recommended to maintain optimal system pressure. Check the compatibility list.
