Description

What does an air processing unit repair kit do?

This repair kit serves as a comprehensive solution for the in-place overhaul of air treatment units, which are critical for drying, regulating, and distributing compressed air within heavy commercial vehicle brake systems. By utilizing high-strength components, these kits ensure the long-term reliability of the pneumatic circuit.

Compatibility and application

The kit is designed to be compatible with Knorr-Bremse systems. It provides a cost-effective alternative to full unit replacement, allowing technicians to address multiple symptoms such as pressure drift or moisture accumulation by renewing internal seals and valve parts.

Installation and maintenance

For successful installation, technicians should ensure surface cleanliness and use the correct lubricant during assembly. It is vital to follow the vehicle manufacturer's service manual for specific tightening torques to ensure the longevity of the repair.

Troubleshooting and selection

Regular inspection of the air processing unit helps prevent system-wide failures. If water collects in the lines or pressure thresholds fluctuate, a targeted repair kit can restore optimal performance to the air brake system.

OE cross-reference

301.03.0070.05 (Air Processing Unit Repair Kit) is the equivalent of the Knorr-Bremse OE number. This part directly replaces Knorr-Bremse OE number K116876N50S3.
