Oil free scroll air compressor of COAIRE that realizes ultra-low noise and clean air

Characteristics of AL Series Products



Highest performance

  • Energy conservation and maximized discharge volume through optimization of scroll airend discharge port
  • Standard application of stainless tank, corrugated type high performance after cooler, and cooling fan to generate clean compress air


Energy saving

  • Energy saving by sequential control :
    Multiple compressors are sequentially started at constant intervals to minimize power variation during start-up, reducing starting current
  • Energy saving through pyramid control : flexible operation of multiple compressors according to air consumption
    : Multiple compressors are flexibly operated according to air consumption to maximally
    suppress power use and promote energy reduction

High reliability

  • Airend with high durability based on simple mechanism and minimal parts
  • Airend specially coated after precise processing for sufficient durability under severe environment
  • Suction filter with decontamination efficiency of 99.9%, high efficiency Sirocco Fan and low-noise cooling fan

User-friendly design

  • Different controllers are applied to different capacities, supporting Korea, English and Chinese languages
  • Reliable components and intelligent Micom controller
  • Diverse models and options to expand the scope of choice for customers


Minimal noise of 49dB among equivalents

  • Continuation of suction, compression and discharge cycles results in scroll mechanism with extremely small torque variation and ultra low noise (49dB) of sound absorption material attached on the front side of external cover
  • Balancing design for crank shaft and turning scroll, and special Vibration-proof rubber at the bottom of airend and motor base


Convenience improvement

  • Condensate drain is installed to remove the condensate in the system. This improve the reliability
  • Ball valve is installed to operate during the partial inspection. (applied to AL30~AL50)
