CompAir L75, L75e and RS
Oil-lubricated screw compressors 75 kW – fixed and variable speed
The 75 kW series is available with fixed speed, variable speed drive (RS) and as a particularly efficient e model, air- or water-cooled.
The revised models need only 2.23 m² of floor space, are up to 7% more efficient and deliver up to 6% more air than their predecessors.
Motor power
75 kW
Pressure
5 to 13 bar
Flow rate
2.1 to 14.9 m³/min

2,23 m²
Why the L75?
The newly designed, semi-integrated GD6 airend has new rotor profiles: more air, less pressure loss, less noise and vibration. CompAir gives a 10-year warranty on it for up to 44,000 operating hours.
All doors are hinged and removable, and the new fine separator has only one seal. This makes maintenance quicker and less expensive.

Frequently asked questions
Fixed speed or variable speed (RS)?
A fixed-speed compressor is most economical when it runs at a steady load. If your compressed air demand fluctuates during the day, a variable speed RS compressor continuously adjusts its delivery and saves electricity. On request, we measure your demand with a compressed air analysis and tell you what is worthwhile.
Air- or water-cooled?
Air-cooled compressors are easier to install. Water-cooled models are worthwhile when the room cannot dissipate the heat or when the waste heat is to be used via the cooling water.
What warranty is available?
With the Assure programme, CompAir extends the warranty as long as maintenance is carried out regularly with original parts. We will be happy to explain the exact conditions for your model.
Who maintains the compressor?
We do. As the CompAir partner for north-western Switzerland, we maintain and repair your system with genuine spare parts and service kits. If your compressed air supply fails, you can reach our on-call service on 062 552 00 88.

Which compressor is right for your business?
Compressed air demand, pressure, operating times and available space determine the choice. We advise you, supply the compressor with air treatment, install the system and take care of service.
