Variable Speed Air Compressor

LRS Series Air Compressor


The CompAir LRS Series of rotary screw air compressor provides maximum efficiency at any level of demand cuts energy costs and saves money. The ability to precisely match output to demand allows the compressors to consume exactly the right amount of energy to do the job, and no more. This is achieved by varying the speed of the drive motor with a level of efficiency which cannot be matched. The right variable speed compressor in the right application delivers significant energy savings and a stable consistent air supply. In addition, precise pressure control and smooth acceleration and deceleration of rotary components extends service life improving payback on your investment.



  • Premium efficiency airend - The high output compression element with slow rotational speed reduces energy costs. The innovative design of the fail safe shaft seal, integrated oil filter, integrated oil separator, and oil regulation valve, ensures external hoses are reduced to a minimum to guarantee the highest levels of quality and reliability are achieved.
  • Eliminates Waste

    • Regulates compressor speed to match output to system demand.
    • Eliminates run-on time during periods of low system demand.
    • Eliminates over pressurization.
