CompAir-LRS-Series-screw_1Regulated Speed Rotary Screw Compressors
L-RS Series 30-132 kW

From 30 to 132 kW, the CompAir regulated speed rotary screw compressors allow you to reduce the cost of ownership and minimize your energy consumption!

The L-RS regulated speed rotary screw compressors can efficiently and reliably handle the varying air demand found in most plant air systems.
These compressors speed up and slow down to match air supply to air demand as it fluctuates. The right variable speed compressor in the right application delivers significant energy savings and a stable air supply at constant pressure.

Key Benefits

  • Premium efficiency airend
    The high output compression element with slow rotational speed reduces energy costs. In addition, the innovative design of the fail safe shaft seal, integrated oil filter and oil regulation valve, ensures external hoses are reduced to a minimum to guarantee the highest levels of quality and reliability are achieved.
  • Remarkable energy savings
    The L30RS to L132RS series of regulated speed rotary screw compressors are able to precisely match power consumption with the system air demand, offering outstanding efficiency and reliability. 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%.
  • Substantial energy savings
    Precisely matching power consumption with the system air demand means no cycles. No cycles means substantial energy savings!
  • 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).
