Screw compressor WALTER SK 75 KSP power input 75 kW, air delivery 12.7 m³/min at 8 bar, direct drive, fixed speed, 7-year warranty
Code: SK-75-KSPProduct detailed description
WALTER SK 75 KSP screw compressor, the more powerful of the pair in a shared housing
SK 75 KSP is the more powerful of the pair in a 2,158 × 1,331 × 1,600 mm housing. At 8 bar it delivers 12.7 m³/min, at 10 bar 11, and at 13 bar 10.2 m³/min.
Compared to SK 55 KSP, that is 35% more air at 8 bar, while the machine is 97 kg heavier (1,225 kg versus 1,128 kg). The G 2″ connection and the 68 dB(A) noise level are the same.
Configuration of this machine
- Screw element coupled directly to the motor · fixed speed without inverter · three-stage oil separation
- Air delivery of 12.7 m³/min at 8 bar, 11 at 10 bar, and 10.2 at 13 bar
- Housing shared with SK 55 KSP, weight 1,225 kg
- G 2″ connection, 68 dB(A) noise level
- Power supply 400 V / 3 / 50 Hz, WALTER CONTROLLER control unit


Who it suits
For operations whose steady demand has outgrown SK 55 KSP and where the footprint should not change. At 13 bar the air delivery remains at 10.2 m³/min, so the machine can also handle piping for higher pressure.
When to choose a different model
Lower demand
For lower consumption, SK 55 KSP in the same housing is sufficient: at 8 bar it delivers 9.41 m³/min and weighs 1,128 kg.
Larger machine
In a 2,727 × 1,666 × 1,800 mm housing, one size up is the SK 90 KSP. It has a DN 65 connection and delivers 16 m³/min at 8 bar.
What the parameters imply — calculated values
The values are calculated from the maximum air delivery at 8 bar and serve for comparing models with each other, not as a guaranteed value.
Frequently asked questions
- How does it differ from the two-stage SF 75 DSP?
- A two-stage variant of the same input power is offered by SF 75 DSP. At 8 bar it delivers up to 15.7 m³/min, i.e. 24% more, but weighs 1,861 kg. The noise level of 68 dB(A) is the same for both.
- What is the noise level of SK 75 KSP?
- 68 dB(A) with a tolerance of ±3 dB, the same as SK 55 KSP.
The machine is covered by a 7-year warranty on the entire machine. Warranty conditions, maintenance, and a comparison of all 17 models can be found in the category WALTER SK KSP screw compressors: direct drive without losses.
Ventilek advises
Two models in the same housing are separated by 20 kW of input power and 97 kg of weight, so the choice depends on the measured consumption, not on space.
