COMMON SIGNS THAT AN AIR DRYER MAY NEED SERVICE

Air dryer system problems may present symptoms such as:

• Excessive moisture in air tanks.

• Water or contamination in pneumatic air lines.

• Abnormal or frequent purge cycles.

• Air leaks around the air dryer assembly.

• Moisture-related corrosion in pneumatic components.

• Reduced performance of the compressed-air system.

These symptoms can also be caused by compressor faults, air leaks, or other pneumatic system issues. Diagnose the system before replacing parts.

WHY REPLACE AN AIR DRYER SERVICE KIT?

Servicing an air dryer with the correct kit can help maintain moisture removal and protect the vehicle's pneumatic system. Using the correct kit is important because the included seals and service components must match the specific air dryer configuration.
