1400 090 012 Compatible Twin Cylinder Compressor

What does a twin cylinder compressor do?

This twin cylinder compressor serves as a vital engine-driven component within the air brake system of heavy commercial vehicles, generating the high-pressure air required for braking and pneumatic operations. By utilizing two piston-cylinder assemblies, this unit provides higher air output than single-cylinder alternatives, ensuring rapid reservoir replenishment for demanding applications.

Compatible vehicles and technical specifications

This specific model is designed for use in Scania vehicles. It features a water-cooled design with an M18x1.5 water inlet and outlet port, alongside an M26x1.5 air inlet port and M22x1.5 air outlet port. The assembly includes a water-cooled valve plate and is engineered to meet the rigorous demands of heavy-duty service.

Installation and maintenance guidance

For professional installation, technicians should verify the through-drive configuration and ensure the M10x1 unloader port is correctly integrated into the system. Maintaining proper coolant flow through the M18x1.5 ports is essential to prevent overheating during continuous operation in heavy commercial vehicle applications.

Selection and system integration

When replacing this unit, confirm compatibility with existing Scania systems to ensure seamless integration of the ESS feature and correct pressure regulation.
