955205RX | Genuine Wabco Air Dryer System Saver 1200

• Compressed air from the engine can contain water vapor.

• The air dryer traps and removes this moisture to prevent freezing in cold weather and rust in the air system.

2. Filters Contaminants

• Removes oil, dirt, and other particulates from the air lines, keeping valves and brake components clean.

3. Protects the Air Brake System

• Prevents frozen brake lines in winter.

• Reduces corrosion in tanks, valves, and lines.

• Extends the life of air brake components.

4. Regenerates Automatically

• Most systems purge collected moisture and contaminants automatically when the air compressor cycles.

1. Moisture in the Air Tanks

• Water or condensation collects in the air tanks

• Indicates the air dryer is not removing moisture effectively

2. Frozen Brake Lines in Cold Weather

• Brakes may lock up or respond sluggishly in freezing temperatures

• Caused by water in the system freezing due to a failing dryer

3. Oil or Contaminants in the Air System

• Oil mist or dirt entering the air lines

• Can damage valves, brake chambers, and other pneumatic components

4. Excessive Air Compressor Cycling

• Air pressure drops quickly because the system is not properly maintained

• The compressor runs more often than normal

5. Air Leaks

• Hissing sounds around the dryer or air lines

• Can be due to worn seals or failed purge valves

6. Brake Warning or Air Pressure Light

• Dashboard warning lights related to the air brake system

• Low pressure warnings may appear more frequently

7. Unusual Purge Behavior

• Air dryer fails to purge moisture automatically

• Continuous purging or no purging at all indicates internal failure

8. Reduced Brake Performance

• Sluggish or inconsistent brake application

• Water or debris may cause brake valves or chambers to stick
