WAB4324802010 | Genuine Wabco HP Air Dryer With Purge Tank

Moisture can:

• Cause rust inside pipes and tanks

• Damage air tools

• Corrode valves and cylinders

Dry air makes equipment last longer.

2. Improve Product Quality

In industries like:

• Spray painting

• Food processing

• Pharmaceuticals

• Electronics manufacturing

Moisture can ruin products. Dry air keeps production clean and consistent.

3. Prevent System Failures

Water in air lines can:

• Freeze in cold temperatures

• Block valves

• Cause pressure drops

• Create sludge in pipes

An air dryer helps keep the system running smoothly.

4. Reduce Maintenance Costs

Less moisture means:

• Fewer breakdowns

• Less corrosion

• Lower repair costs

• Less downtime

5. Meet Industry Standards

Some industries require very dry air to meet safety and quality regulations (especially medical and food industries).

1. Water Coming Out of Air Lines

• Water sprays from hoses

• Wet air when using tools

• Moisture in drain valves

This is the most obvious sign.

2. Rust in Pipes or Tank

• Rust flakes in air lines

• Corrosion inside fittings

• Brown water when draining tank

Moisture is staying in the system instead of being removed.

3. Poor Tool Performance

• Air tools lose power

• Tools stick or run rough

• Internal rust damage

Moisture can damage moving parts inside tools.

4. Bad Paint or Finish Quality

• Bubbles in paint

• Fish-eyes or streaks

• Uneven coating

Very common in body shops when the dryer fails.

5. High Dew Point Warning (Industrial Systems)

Some dryers have dew point indicators.

• If dew point rises above normal range, the dryer isn’t removing enough moisture.

6. Dryer Running Constantly or Not Turning On

• Refrigerated dryer not cooling

• Desiccant dryer not cycling properly

• System alarms

Mechanical or electrical failure may be happening.

7. Excessive Pressure Drop

• Air pressure lower than usual

• System struggling to keep up

Clogged filters or saturated desiccant may be restricting airflow.

8. Desiccant Dust in Lines (Desiccant Dryer Only)

• White powder in air lines

• Contaminated equipment

This means the drying material is breaking down.
