CompAir-LRS-Series-screwL-RS Series 22-30 kW
Fixed & Regulated Speed Rotary Screw Compressors

From 22 to 30 kW, the L-RS series of fixed & regulated speed screw compressors provide a premium efficiency, high quality, reliable and energy saving compressed air package.

The L-RS series compressors come equipped with an energy saving high efficiency electric motor which reduces CO2 emissions.

Energy costs can be reduced thanks to the high output compression element with slow rotational speed. In addition, the highest levels of quality and reliability can be achieved due to the innovative design of the fail safe seal, integrated oil filter and oil regulation valve, ensuring external hoses are reduced to a minimum.

All of the L-RS series fixed & regulated speed rotary screw compressors are available with an integrated dryer. To maximize energy efficiency and eliminate expensive air loss, this option comes complete with a dryer and water separator, both fitted with zero loss drains.

Key Benefits

  • Low noise levels
    The high efficiency and extremely quiet thermostatically controlled motor driven fan, allows the L-RS series fixed & regulated speed rotary screw compressors to be operated in the work place.
  • Reliable operation
    Operational parameters are continuously monitored with the DELCOS Pro intelligent controller, for the continued reliable operation, and on-going protection, of your investment.
  • Reduced cost of ownership
    With the L23RS to L29RS series of regulated speed compressors you can reduce the annual cost of ownership thanks to the remarkable energy savings you can achieve. When compared with a typical oil lubricated rotary screw air compressor operating at 70% load, with the CompAir regulated speed L-RS series (also operating at 70% load), it is possible to reduce the associated energy cost by up to 25%.
  • Low service costs
    The design of the L-RS series fixed & regulated speed rotary screw compressors assures the service points are readily accessible. The enclosure side doors are hinged and removable allowing complete access to all service points. And, in addition, a reduced number of moving parts lowers maintenance costs.
  • Free of charge AssureTM extended warranty
    The CompAir AssureTM Warranty and Service programs will assure you up to 44,000 hours / 6 years (whichever is the soonest) peace of mind, and is one of the most generous warranties available in the industry. It is also totally free to the compressor owner (subject to Terms & Conditions).
