Oil Free Compressors

Over the past 60 years, Atlas Copco has pioneered the development of oil-free air compressor technology, resulting in a range of oil-free air rotary screw compressors to suit applications that cannot compromise when it comes to the purity of compressed air. With certification to ISO 8573-1 CLASS 0 standard, Atlas Copco sets a standard for the industry: “100% oil-free air”.

“We are very pleased to offer our customers a compressed air solution which eliminates risk of contamination by oil. These test results prove that Atlas Copco’s oil-free rotary screw compressors are not just the right choice in terms of operating costs, but also constitute the best choice when it comes to managing risks.”

– Mr. Luc Hendrickx, President of Atlas Copco’s Oil-free Air division

Contamination by even trace quantities of oil can result in damaged batches or products, high rejection rates and returns, and costly production downtime and clean-up. Industries that risk contaminating their products with oil may expose themselves to product recalls, legal action and the negative consequences these have on company reputation and brand equity.

Risk of any contamination by oil is effectively eliminated using our oil-free compressors in manufacturing. Atlas Copco has consistently proven its world leadership in the compressor market by setting a new standard for compressed air purity.

The SF, Z and AQ Series ranges of oil-free piston industrial air compressors can fit the following range of specifications:

  • 2 to 75 hp
  • 2.1 to 86.5 cfm
  • Pressure variation 116 – 145 psig
