II31951 KNORR-BREMSE Single Cylinder, Air Compressor

This single cylinder air compressor is engineered to provide reliable air pressure for heavy commercial vehicle pneumatic systems. Designed with a robust structure, it ensures consistent performance in demanding environments by utilizing high-strength components and a water-cooled system for optimal thermal management.

II31951 is the OE-equivalent of the KNORR-BREMSE II31951 single cylinder air compressor used in KNORR-BREMSE systems. This component is manufactured to meet strict technical standards, ensuring seamless integration and long-term durability within the air brake system.

For workshop technicians, this part features a cylinder diameter of Ø88.00 mm and a 50mm stroke to maintain high-pressure output. The water-cooled design includes specific inlet and outlet ports (M22x1,5) to facilitate efficient heat dissipation. Regular inspections of the water-cooled valve plate and connection points are recommended during routine maintenance to ensure optimal system pressure.

The VADEN ORIGINAL II31951 is a high-grade replacement part designed for professional heavy commercial vehicle service. It maintains precise tolerances for the M26x1,5 air ports to ensure reliable operation in critical braking applications.
