All our screw compressors share the same base: a lubricated, air-cooled screw element, managed by an electronic controller with a display showing pressure, temperature, operating hours and the service reminder. What changes from one series to the next is what is fitted around the compressor: nothing at all, an air receiver and a dryer, wheels, or precision filtration at 16 bar.
This article brings all the specifications together in tables, series by series, using the values from our data sheets. To compare two to four models of your choice line by line, you can also use the compressor comparison tool.
The four series at a glance
| Series | What is supplied | Power ratings | Pressure | Who it is for |
|---|---|---|---|---|
| S series | The screw compressor on its own | 5.5 to 22 kW | 8 to 13 bar depending on the model | Replacing a machine, reinforcing an existing network, building your own installation |
| K series | Compressor, air receiver, refrigerated dryer and filtration on one frame | 7.5 to 15 kW | 8, 10 or 13 bar, your choice | New installation, workshops that want dry air without assembling anything |
| M series | Compressor on a tank and on wheels | 7.5 and 22 kW | 10 or 12.5 bar | Air needed in several places, job sites, machine fleets |
| L series | 16 bar compressor, 16 bar tank, dryer and precision filtration | 11 to 22 kW | 8 to 16 bar | Laser cutting machines |
S series - the screw compressor on its own
The S series is supplied without air receiver or dryer. All its models have a permanent magnet motor with direct drive; from 5.5 to 15 kW, they start via a variable frequency drive.
| Model | Power | Pressure | Flow | Noise level | Dimensions (L × W × H) | Weight | Connection |
|---|---|---|---|---|---|---|---|
| S 55 | 5.5 kW | 8 bar | 0.6 m³/min | 65 to 68 ± 2 dB(A) | 750 × 550 × 750 mm | 98 kg | G 1/2" |
| S 75 | 7.5 kW | 8, 10 or 13 bar | 1.1 m³/min at 8 bar | 65 to 68 ± 2 dB(A) | 850 × 650 × 800 mm | 130 kg | G 1/2" |
| S 110 | 11 kW | 8, 10 or 13 bar | 1.7 m³/min at 8 bar | 68 to 72 ± 2 dB(A) | 1050 × 700 × 1000 mm | 210 kg | G 1/2" |
| S 150 | 15 kW | 8, 10 or 13 bar | 2.2 m³/min at 8 bar | 68 to 72 ± 2 dB(A) | 1050 × 700 × 1000 mm | 220 kg | G 3/4" |
| S 220 PM | 22 kW | 10 bar | 3.2 m³/min at 10 bar | 68 to 72 ± 2 dB(A) | 1100 × 850 × 1000 mm | 310 kg | G 1" |
The S 220 PM is the industrial machine of the range: at 22 kW, it delivers 3.8 m³/min at 7 bar, 3.6 m³/min at 8 bar, 3.2 m³/min at 10 bar and 2.9 m³/min at 12.5 bar.
K series - the 4-in-1, ready to connect
On the K series, the air receiver, refrigerated dryer and filtration are mounted on the same frame as the compressor. The K 110 and K 150 use the same compressor as the S 110 and S 150.
| Model | Power | Flow at 8 bar | Air receiver | Noise level | Dimensions (L × W × H) | Weight | Connection |
|---|---|---|---|---|---|---|---|
| K 75 | 7.5 kW | 1.1 m³/min | 420 L | 66 ± 2 dB(A) | 1650 × 850 × 1200 mm | approx. 310 kg | G 3/4" |
| K 110 | 11 kW | 1.7 m³/min | 340 L | 68 to 72 ± 2 dB(A) | 1800 × 730 × 1530 mm | 400 kg | G 1/2" |
| K 150 | 15 kW | 2.2 m³/min | 340 L | 68 to 72 ± 2 dB(A) | 1800 × 730 × 1530 mm | 400 kg | G 3/4" |
All three models can be ordered in 8, 10 or 13 bar, and in three colour schemes: blue, black and yellow, or black and red.
Flow according to the chosen pressure
On the S and K series, the pressure is chosen when ordering. The higher the pressure, the lower the flow: it is the same machine compressing the air harder. Here are the values from our data sheets, identical for both series at the same power rating.
| Power | Models | At 8 bar | At 10 bar | At 13 bar |
|---|---|---|---|---|
| 7.5 kW | S 75, K 75 | 1.1 m³/min | 0.95 m³/min | 0.8 m³/min |
| 11 kW | S 110, K 110 | 1.7 m³/min | 1.4 m³/min | 1.1 m³/min |
| 15 kW | S 150, K 150 | 2.2 m³/min | 2.0 m³/min | 1.6 m³/min |
So choose the pressure your tools actually need, not the highest one available. Our article on calculating your compressor pressure explains how.
M series - the screw compressor on wheels
| Model | Power | Pressure | Flow | Tank | Noise level | Dimensions (L × W × H) | Weight |
|---|---|---|---|---|---|---|---|
| M 75 | 7.5 kW | 10 bar | 1.0 m³/min at 10 bar | 180 L | 68 to 72 ± 2 dB(A) | 1350 × 500 × 1150 mm | 240 kg |
| M 220 | 22 kW | 12.5 bar | 2.0 m³/min at 12.5 bar | Twin tank, 180 L in total | 68 to 72 ± 2 dB(A) | 1500 × 700 × 1200 mm | 680 kg |
The M 75 has inverter start; the M 220 uses direct start, with coupling drive.
L series - 16 bar and filtered air for laser cutting
| Model | Power | Pressure | Flow | Tank | Dimensions (L × W × H) | Weight |
|---|---|---|---|---|---|---|
| L 110 | 11 kW | 8 to 16 bar | 0.8 m³/min | 340 L, 16 bar | 1750 × 700 × 1610 mm | 480 kg |
| L 150 | 15 kW | 8 to 16 bar | 1.3 m³/min | 500 L, 16 bar | 1800 × 800 × 1710 mm | 690 kg |
| L 220 | 22 kW | 8 to 16 bar | 1.8 m³/min | 500 L, 16 bar | 1900 × 900 × 1710 mm | 750 kg |
All three models include a refrigerated dryer (dew point 3 to 10 °C) and precision filtration (particles 0.01 µm, oil 0.001 ppm). Their noise level is 72 ± 3 dB(A). Everything is covered in detail in our article on the compressor for laser cutting.

How to choose from these tables
- Start with the flow. Add up the consumption of the tools used at the same time and keep a margin. The configurator does the calculation for you.
- Set the pressure. It depends on the most demanding tool, not on a wish to have something in reserve.
- Choose the series. Existing network or plant room: S series. New installation and dry air without assembly: K series. Air needed in several places: M series. Laser cutting: L series.
