Lubricated Rotary Screw Compressor 75 kW

CompAir L75, RS

The 75 kW range of lubricated screw compressors comprises of fixed speed and regulated speed (RS) models

CompAir's 75 kW screw compressor range has been enhanced with an additional "e" model offering improved performance in this kW size while at the same time being around 10% smaller than comparable machines.

The upgraded 75kW screw compressors from CompAir have only a 2.23m2 footprint for easier installation in more restrictive locations.

The newly redesigned models offer quick release panel access for easier servicing, redesigned & improved service parts like separators & filters. With an efficiency improvement of up to 6.8%, and a higher flow rate up to 6% from the brand new airends, this improved performance and space saving ability delivers significantly lower lifetime costs.

Designed & manufactured at the centre of excellence in Germany, the latest changes represent a continuing improvement to a range which has been developed over many decades.

Outstanding Benefits

The new compressors are available in both fixed and regulated speeds – which can help reduce a system’s total cost of ownership significantly – as well as air-cooled and water-cooled options. 

Pressure range : 5 to 13 bar

Volume flow : 2.1 - 14.9 m3/min

Motor power : 75 kW

The new models offer the following improvements:

  • Re designed GD6 semi integrated airend with better performance that can reach 5-6 % improvement  at high speed
  • 3-8% efficiency improvement for complete package standard models.
  • Smaller footprint by 11% compared to old models
  • Implementation of new automatic oil regulation valve for variable speed models provides better efficiency
  • New fine separator with 1 integrated seal , easy maintenance – no need to remove and re install o-rings

Premium compressor design and industry leading warranty

The compressors are equipped with a premium high efficiency electric motor, which can be upgraded to an ultra efficient energy saving IE4 electric motor.

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.

CompAir Genuine Parts ensure the safe and economical operation of your system. Compliance with the maintenance intervals is essential for energy efficiency. In the event of a pressure loss due to improper filters, the high energy requirement exceeds the cost of maintenance. Do not endanger the safety of your production. Externally identical components can differ considerably.

CompAir Service Kits include all genuine parts and wear parts for the respective maintenance and ensure optimum operation of the systems.
