1100 300 001 Compatible Triple Cylinder Air Compressor

What does a triple cylinder air compressor do?

This triple cylinder air compressor serves as a vital component in the pneumatic system of heavy commercial vehicles, generating the compressed air required for braking systems and auxiliary pneumatic equipment. By utilizing three cylinders, this unit provides a higher air flow rate compared to standard single or twin-cylinder models, facilitating rapid pressure buildup in the air circuit of buses and multi-axle vehicles.

Vehicle and engine compatibility

This specific model is engineered for compatibility with Mercedes-Benz CITARO (O 530) models including N, MUE, G, GN3, and LÜ variants, as well as Setra Series 400 MultiClass models. It is also suitable for Mercedes-Benz CONECTO (O 345) and CAPACITY units, specifically when paired with OM 457 HLA, OM 457 LA, or OM 447 HLA engines.

Installation and maintenance guidance

Designed with a water-cooled body to manage thermal loads during continuous operation, this compressor features an Ø85.00 mm bore and a stroke of 56/37 mm. Installation requires careful attention to the M16x1,5 water inlet and outlet ports to ensure proper cooling flow. Technicians should verify that the unloader port (M10x1,5) and through drive configuration align with the existing engine mounting.

Operational reliability

Maintaining regular inspections of the water-cooled valve plate and air inlet ports helps prevent system pressure drops. Ensuring correct fitment with OE systems ensures long-term reliability for fleet operations. Consult your authorized distributor.
