L50, L80 & L140, RS

Main_pic-l50-l80-l140Well known in the industry for quality and reliability CompAir continuously develops the L-Series achieving cutting edge performance and efficiency. The premium efficiency range L50, L80 and the new L140 feature an extra large airend contributing to typically 8% energy cost savings.

The screw compression element is the heart of the compressor and therefore CompAir keeps the design and manufacture in-house, using the latest CNC rotor grinding machinery, coupled with online laser technology.

The resulting reliability and performance ensure that operating costs will remain low throughout the compressors life.

DesignThe compressors of this range are equipped with a larger airend making them outstanding in efficiency. Thanks to the reduced rotational speed, significant energy savings can be achieved. Furthermore, the noise level is reduced.

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 highest levels of quality and reliability are achieved.

This range of compressors features an extra large airend with optimised rotor tip speed and achieves up to 8% energy savings.


  • Less energy costs
  • Lower noise levels
  • Lower total cost of ownership
  • Lower maintenance costs
  • Short payback time
