Atlas Copco Quality Air

Why You Need Quality Air

Without air treatment, unwanted contaminants and particulates can make their way into an air system and have harmful side effects. Compressed air contains:

  • oil
  • solid particles
  • water vapors
Together, they form an abrasive, often acidic, oily sludge. This murky mix will enter the compressed air system, corroding pipe work, damaging pneumatic tools and potentially compromising final products


The Cost of Poor Quality Air

Untreated compressed air can cause substantial problems and costs:

• Your air tools have less power, more failures and, ultimately, a shorter lifetime.
• Materials and products that come into contact with untreated air run the risk of contamination or damage.
• Compressed air pipe work will corrode, leading to leaks. 

Standalone or Integrated

Separate dryer:
• Plug-and-play installation.
• Single electrical connection.
• All units pre-commissioned.
• Self-regulating.
• Pressure dew point display with high/low pressure dew point alarm and status of refrigerant, compressor and fan.

Full feature:
• Saves space when footprint is a priority.
• Compressor and air treatment
components are designed, built and tested to work together to provide optimal quality air.
