Code: SF-37-KSP
Product detailed description
Screw compressor WALTER SF 37 KSP, middle model of the medium housing
The SF 37 KSP is the middle one of three models in the 1,500 × 1,030 × 1,280 mm housing: below it is the SF 30 KSP, above it the SF 45 KSP.
At 8 bar it delivers up to 6.2 m³/min, at 10 bar 5.6, and at 13 bar 5 m³/min. It weighs 591 kg, i.e. 73 kg more than the SF 30 KSP.
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 the SF 30 KSP and SF 45 KSP, weight 591 kg
- Connection G 1½″, noise level 66 dB(A)
- Power supply 400 V / 3 / 50 Hz, WALTER CONTROLLER control unit
Who it suits
For medium-sized operations with several appliances running at once, where consumption fluctuates. The inverter keeps the pressure stable even as air consumption changes.
When to choose a different model
Two-stage machine
The two-stage SF 37 DSP delivers up to 7.5 m³/min at 8 bar, 21% more. However, it weighs 841 kg compared to 591 kg.
Constant demand
For constant consumption, the SK 37 KSP with fixed speed is sufficient. At 8 bar it delivers 6.2 m³/min, the same as the maximum air delivery of the SF 37 KSP.
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 much air does it deliver at the lowest speed?
- At 8 bar, 2.48 m³/min, i.e. 40% of the maximum air delivery. At 10 bar it is 2.24 m³/min.
- How much do the models in the same housing weigh?
- SF 30 KSP 518 kg, SF 37 KSP 591 kg, and SF 45 KSP 690 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
The middle model is suitable where it is not certain whether operation will grow upward or downward: either way, you stay in the same housing and with the same G 1½″ connection.
