CompAir has extended its oil free rotary screw compressor range with the new D37-D75 (RS) Series.

The new models are:

• Class Zero Oil FREE Rotary Screw Compressors

• Nominal Power from 37-75 kW

• Capacity of up to 12.7 m³/min (@ 7 bar g)

• Complementing the established 75 to 315 kW model range

• Fixed Speed and Variable Speed (RS) Models

• Air-cooled and Water-cooled

• Numerous Further Options

The range covers air and water-cooled models from 37 to 75 kW and is available in both fixed and regulated speeds (RS) delivering ISO 8573-1:2010 Class 0 certified 100% oil-free air for the most critical applications, e.g. within the food and beverage, pharmaceutical, textile, and electronics industries. No oil is used in the compression elements, neither for sealing or lubricating the rotors, nor for cooling the compression process directly, reducing the risk of costly downtime and contaminated products.

The complete range now runs from 37 to 315kW, Pressure range 4 to 10 bar, Volume flow 5.1 to 51.8 m³/min and can offer:

  • Air purity that meets the most stringent hygienic standards
  • Award-winning Class 0 Certified oil & silicone-free screw compressors
  • High efficiency, low pressure losses, low temperature operation & economical control
