1400 090 006 Twin Cylinder Air Compressor for Scania

What does a twin cylinder compressor do?

This twin cylinder air compressor serves as a critical component within the air brake system of heavy commercial vehicles, providing the necessary compressed air through two piston-cylinder assemblies. By utilizing two compression strokes, it delivers significantly higher air output than single-cylinder units, making it ideal for vehicles with high air demand. This unit is built with high-strength components to withstand demanding service conditions.

Vehicle compatibility and technical specifications

This specific model is compatible with Scania trucks and is designed to meet the requirements of heavy-duty braking systems. It features a water-cooled configuration with a 720cm³ swept volume and an 86.00 mm cylinder bore. The unit includes an ESS feature and a water-cooled valve plate to maintain optimal thermal management during operation.

Installation and maintenance guidance

For proper installation, technicians should verify the mounting interface and port connections, including the M26x1.5 air inlet and M18x1.5 water ports. Regular inspection of the drive gear and cooling lines is recommended to ensure reliable performance in the field. Consult your authorized distributor for fitment verification.

System reliability and troubleshooting

Maintaining correct oil levels and inspecting the water cooling circuit helps prevent premature wear of the internal piston assemblies.
