WALTER SF 7,5 KSP Screw Compressor input power 7.5 kW, air delivery 0.42–1.15 m³/min at 8 bar, direct drive, inverter, 7-year warranty
Code: SF-7-5-KSPProduct detailed description
WALTER SF 7,5 KSP screw compressor with screw-type oil separator
At 8 bar, the SF 7,5 KSP delivers up to 1.15 m³/min, i.e. 21% more than the SF 5,5 KSP in the same housing. The regulation range at 8 bar is 0.42–1.15 m³/min.
Weight 227 kg, G ¾″ connection and noise level 60 dB(A) remain the same as on the smaller model. So it's only a matter of air demand.
Configuration of this machine
- Single-stage screw block · direct drive 1:1 · IE4 motor (IE5 optional) with inverter · screw-type oil separator
- Three pressures: 8, 10 and 13 bar
- Housing shared with the SF 5,5 KSP, weight 227 kg
- G ¾″ connection, noise level 60 dB(A)
- Power supply 400 V / 3 / 50 Hz, WALTER CONTROLLER control unit


Who it suits
Suitable where 5.5 kW is not enough, but the machine needs to stay in the smallest housing of the range. At a pressure of 13 bar, it delivers up to 0.95 m³/min.
When to choose a different model
Lower consumption
The SF 5,5 KSP is housed in the same housing and delivers up to 0.95 m³/min at 8 bar.
Higher power
The SF 11 KSP delivers up to 1.65 m³/min at 8 bar, but it is housed in a larger housing (1,090 × 730 × 1,080 mm) and weighs 243 kg.
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 the SF 7,5 KSP differ from the SF 5,5 KSP?
- By power output. The housing, weight, connection and noise level are the same; the maximum air delivery at 8 bar is 1.15 versus 0.95 m³/min.
- Is it also made for 13 bar?
- Yes, the model is manufactured for 8, 10 and 13 bar. At 10 bar it delivers up to 1 m³/min and at 13 bar up to 0.95 m³/min.
The machine comes with a 7-year warranty covering the entire machine. Warranty terms, maintenance, and a comparison of all 19 models can be found in the category Screw compressors WALTER SF KSP: inverter and direct drive.
Ventilek advises
The same housing and the same connection mean that both of the smallest models are connected in the same way. So choose based only on how much air you actually need.
