kz4331x50 KNORR-BREMSE Twin Cylinder Air Compressor

The heavy-duty twin cylinder air compressor is a critical component for maintaining pneumatic pressure within the braking system of heavy commercial vehicles. Designed with high-strength components, this unit ensures consistent air delivery to support reliable braking performance under demanding operating conditions. Its robust construction and specialized water-cooling design allow it to function effectively in high-temperature environments.

This specific model is the OE-equivalent of the KNORR-BREMSE KZ433\1X50 Twin Cylinder Air Compressor used in VOLVO heavy commercial vehicle systems. It is also fully compatible with several other reference numbers including KNORR-BREMSE 1186722SP, KZ433, and KZ433\1RM. It serves as a direct replacement for VOLVO 1080437, 1186722, 1188844, 1570594, 1590264, and 1612335, ensuring seamless integration with existing hardware.

Workshop technicians will find the installation straightforward due to the standardized M26x1,5 air ports and M16x1,5 water ports. The unit features a through-drive design and an integrated ESS feature to optimize pneumatic efficiency. Regular maintenance should include checking the water inlet/outlet connections and ensuring the cooling system remains unobstructed to prevent overheating during long-haul operations.

When replacing an aging compressor, it is vital to verify the compatibility of the gear and port specifications. This unit is optimized for heavy commercial vehicle service environments where reliability is paramount for safety and uptime.
