CompAir L07 to L22
Oil-lubricated screw compressors 7 to 22 kW – fixed and variable speed (RS)
Reliable and flexible: the L07 to L22 are available with fixed or variable speed, base-mounted or as an Airstation with receiver and built-in refrigeration dryer, with heat recovery on request.
The compressor alone needs only 0.4 m² of floor space. As a complete station, it also saves space and installation work.
Motor power
7 to 22 kW
Pressure
5 to 13 bar
Flow rate
0.41 to 3.65 m³/min
Why the L07 to L22?
The compression stage with built-in oil separator, oil filter and thermostatic valve runs at low speed. This reduces power consumption and eliminates external hoses that could leak.
A combined air/oil cooler keeps the oil temperature constant and prevents condensate in the compressor. It is filled with FluidForce oil at the factory; the oil change is only due after up to 4,000 hours.
- In-house low-speed compression stage
- High-efficiency IE3 motor
- Maintenance-free automatic belt tensioning
- Oil change interval up to 4,000 hours
- Quiet enough to be installed at the workplace
- Operation up to 45 °C ambient temperature
- Footprint from 0.4 m²
Delcos Pro SE controller
The Delcos Pro SE continuously monitors the compressor and shows all values in plain text on a graphic display. It can be mounted on the top or front of the compressor.
- System and network pressure, compression temperature
- Running and load hours, service indicator
- Timed and remote start and stop
- Second pressure setting
- Automatic restart after a power failure
- RS485 Modbus RTU, data logging on micro SD

¹⁾ Data measured and stated in accordance with ISO 1217 Edition 4, Annex C & E, within the following tolerances: inlet pressure 1 bar a, inlet temperature 20 °C, relative humidity 0% (dry)
²⁾ Free-field sound measurement in accordance with ISO 2151 and ISO 9614-2, tolerance ± 3 dB(A).
³⁾ The refrigeration dryer requires a separate electrical connection. All data refer to DIN ISO 7183, 8573-1:2010 (Class 4, pressure dew point 3 °C). Further information can be found in the separate dryer documentation.
Data from CompAir. Flow rate to ISO 1217, Annex C or E. We will be happy to determine with you which version and pressure are right for your system.
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.
What is an Airstation?
Compressor, compressed air receiver and refrigeration dryer in one package. It takes up less space, and installation is done with a single connection.
Can the waste heat be used?
Yes. Up to 94 % of the energy consumed turns into heat. With heat recovery you can use it to heat water or rooms. More on this under Heat recovery.
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.
