LRS Series Air Compressor

CompAir LRS Variable Speed Lubricated Rotary Screw 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.
