Description
What does a twin cylinder compressor do?
This water-cooled twin cylinder compressor is a critical component in the air brake system of heavy commercial vehicles, designed to provide high-volume compressed air through two piston-cylinder assemblies. By utilizing two compression strokes per crankshaft revolution, this unit ensures faster reservoir filling and higher air output compared to single-cylinder alternatives, making it ideal for high-demand applications.Technical specifications and compatibility
This specific unit is engineered for heavy-duty performance and is compatible with Knorr-Bremse systems. It features a through-drive design, an M12x1.5 air unloader port, and M18x1.5 water inlet and outlet ports to ensure seamless integration into the vehicle's existing pneumatic and cooling circuits.Installation and maintenance guidance
Maintenance of this compressor should focus on the cooling circuit to ensure the water-cooled valve plate functions correctly under heavy loads. Technicians should regularly inspect the M18x1.5 ports for leaks and verify the integrity of the ESS feature to maintain optimal system pressure and prevent air leaks during braking cycles.OE cross-reference

FAQ
What is the main function of this twin cylinder compressor?
It generates high-volume compressed air via two piston assemblies to ensure rapid reservoir filling in heavy commercial vehicle brake systems.
How does a water-cooled compressor differ from an air-cooled one?
This water-cooled model is tied into the engine cooling circuit to prevent overheating during sustained heavy use, which is vital for long-haul operations.
What are the key technical specifications for this unit?
The unit features a Ø75.00 mm bore, 50 mm stroke, 440cm³ swept volume, and is equipped with an ESS feature and water-cooled valve plate.
What should technicians check during installation?
Ensure the M18x1.5 water ports are correctly connected to the cooling circuit and the M12x1.5 unloader port is clear of debris.
What are the OE reference numbers of this part?
1400 040 001 directly replaces Knorr-Bremse OE number KZ996.
