L55 - L140, RS

Quality pays off. The L-Series from CompAir.

L30-50_DelcosXL_offen

Well known in the industry for quality and reliability, CompAir continuously develops the L-Series achieving cutting edge performance and efficiency. The L55 - L140 range of lubricated screw compressors comprises of fixed speed and regulated speed (RS) models. All models are optionally available with integrated heat recovery.

  • High reliability and high quality compressed air
  • Comprehensive and user-friendly touch-screen compressor controllerOptimized-L 75 RS_offen
  • Superior energy efficiency
  • High flexibility
  • Small footprint
  • Excellent accessibility contributing to the low maintenance costs

The high output in-house made airend with slow rotational speed combined with the energy saving IE 3 electric motor delivers optimum energy efficiency.

The RS (regulated speed) efficiently handles the varying air demand found in most plant air systems.
The compressors incorporate quality components, such as high performance separator filter, large surface after cooler and thermostatically controlled motor driven fan.

The design concept is not only based on energy efficiency but also on high availability and low maintenance costs.

Therefore these packages ensure all service points are easily accessible. The reduced number of moving parts contributes to lower maintenance costs additionally.

L80 and L140 with efficiency upgrade

These models feature a an extra large airend with optimised rotor tip speed and achieve up to 8% energy savings.L55-75-F-SR-01-Airend-trimmed
