Two Stage Oil-Free Rotary Screw Compressors

Fixed and regulated speed rotary screw air compressors CompAir has launched a completely new range of high efficiency, oil-free two-stage rotary screw compressors to further enhance its successful and award winning D-Series. With the addition of 8 new models, these high output oil-free machines now cover a wide flow range from 5.1 to 51.8 m3/min. The D37 to D315 models are fixed speed and the D37RS to D315RS models are regulated speed
  • 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

No matter what industrial sector, there is a growing demand for higher quality, oil-free compressed air that meets the stringent quality standards. Whether it is needed for food and beverage or chemicals production, supply of pharmaceuticals, electronics or sensitive components, manufacturers will no longer accept the risk of product or equipment contamination. For this reason, CompAir’s 2 stage oil-free models offer the highest standard of air purity and has been certified ISO 8573-1 Class Zero (2010) oil and silicone free.

Guaranteed efficiency is provided by the excellent high quality IE3 or IE4 electric motor, along with legal conformity, high reliability and operational safety. These are great benefits in addition to automated motor lubrication. These oil free rotary screw compressors utilise two efficient radial fans in accordance with ErP Efficiency Legislation 2015, offering low noise levels, low pressure loss and excellent cooling performance.  The closed water circuit for airend cooling achieves a constant low temperature level, also meaning that fewer gearboxes are required. The high output, two-stage airend design provides 100% oil-free and near isothermal compression with high reliability thanks to constant low temperatures, allowing use in demanding applications in up to 45°C ambient temperatures.
