APPLICATIONS

FUNCTION

The System Saver HP Air Dryer removes moisture and helps separate contaminants from compressed air before the air enters the vehicle's pneumatic system. This helps reduce moisture-related corrosion and supports reliable operation of air brake valves, lines, and other air system components.

COMMON SIGNS OF AIR DRYER FAILURE

A worn, damaged, or failing air dryer may cause symptoms such as:

• Excessive moisture in air tanks

• Water or contamination in pneumatic air lines

• Frequent air dryer purge cycles

• Air leaks around the dryer assembly

• Moisture-related corrosion in air system components

• Reduced air system performance or pressure-related issues

These symptoms can have other causes. Inspect the complete compressed air system before replacing the air dryer.

WHY REPLACE AN AIR DRYER?

Replacing a faulty air dryer helps control moisture in the compressed air system, protects downstream pneumatic components, and supports dependable air brake operation. Use the correct System Saver HP configuration and compatible replacement cartridge for the vehicle.
