Screw compressor WALTER SF 22 KSP power input 22 kW, air delivery 1.44–4 m³/min at 8 bar, direct drive, inverter, 7-year warranty
Code: SF-22-KSP
Product detailed description
WALTER SF 22 KSP screw compressor with inverter, lighter variant of SF 22 DSP
Compared to the two-stage SF 22 DSP, the SF 22 KSP is simpler and lighter: it weighs 418 kg instead of 738 kg and takes up a housing of 1,300 × 880 × 1,170 mm.
At 8 bar it delivers up to 4 m³/min, at 10 bar 3.6 and at 13 bar 3.3 m³/min. The two-stage model delivers 5% more at 8 bar.
Configuration of this machine
- Single-stage screw airend · direct drive 1:1 · IE4 motor (IE5 optional) with inverter · submerged oil separator
- Three pressures: 8, 10 and 13 bar
- Housing shared with SF 18,5 KSP, weight 418 kg
- G 1″ connection, noise level 64 dB(A)
- Power supply 400 V / 3 / 50 Hz, WALTER CONTROLLER control unit
Who it suits
For operation that won't run full shifts. Two-stage compression pays off most with machines running continuously. Shorter operation with fluctuating demand can be handled by a single-stage machine with inverter.
When to choose a different model
Continuous operation
SF 22 DSP is a two-stage unit with an IE5 magnetic motor and delivers up to 4.2 m³/min at 8 bar. However, it is larger (1,500 × 1,037 × 1,273 mm) and 320 kg heavier.
More air
SF 30 KSP delivers up to 5.21 m³/min at 8 bar. It is in a larger housing (1,500 × 1,030 × 1,280 mm) and the connection is G 1½″.
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
- What is the difference compared to SK 22 KSP?
- SK 22 KSP is the same machine without an inverter. It has the same maximum air delivery at 8 bar, 4 m³/min, but with fixed speed it does not adapt at lower demand.
- How much does SF 22 KSP weigh?
- 418 kg, 40 kg more than SF 18,5 KSP in the same housing. The two-stage SF 22 DSP weighs 738 kg.
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
A two-stage block delivers more air, but also more weight. Before deciding, find out how many hours per year the machine will actually run.
