Screw compressor WALTER SF 37 DSP input power 37 kW, air delivery 3–7.5 m³/min at 8 bar, two-stage, IE5 motor, 7-year warranty
Code: SF-37-DSP
Product detailed description
Two-stage screw compressor WALTER SF 37 DSP for pressure up to 13 bar
The SF 37 DSP is the smallest two-stage machine in the range that is also made for 13 bar. At 8 bar it delivers up to 7.5 m³/min, at 10 bar 6.72 and at 13 bar 5.65 m³/min.
The housing 1,610 × 1,043 × 1,380 mm is the same as on the SF 30 DSP, and the machine is only 15 kg heavier: 841 kg versus 826 kg. You therefore get higher performance without a larger footprint.
Configuration of this machine
- Two-stage screw block · direct drive 1:1 · IE5 magnetic motor with inverter
- Three pressures: 8, 10 and 13 bar
- Housing shared with the SF 30 DSP, weight 841 kg
- Connection G 1½″, noise level 65 dB(A)
- Power supply 400 V / 3 / 50 Hz, WALTER CONTROLLER control unit
Who it suits
Suitable for systems with tools requiring higher pressure, where smaller two-stage models lack 13 bar. At 13 bar the control range is 2.26–5.65 m³/min.
When to choose a different model
Lower demand
SF 30 DSP has the same housing and delivers up to 5.86 m³/min at 8 bar. However, it does not have 13 bar.
Higher demand
SF 45 DSP delivers up to 9.14 m³/min at 8 bar. It is in a larger housing (2,132 × 1,318 × 1,600 mm) and weighs 1,144 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
- Is the SF 37 DSP better than the SF 37 KSP?
- At 8 bar it delivers up to 7.5 m³/min compared to 6.2 m³/min for the single-stage SF 37 KSP, i.e. 21% more. However, the two-stage machine is heavier: 841 kg compared to 591 kg.
- What is the noise level?
- 65 dB(A) with a tolerance of ±3 dB.
The machine is covered by a 7-year warranty on the entire machine. Warranty terms, maintenance, and a comparison of all 13 models can be found in the category WALTER SF DSP screw compressors: two-stage compression.
Ventilek’s advice
In the two-stage range, 13 bar is available starting from this size. The housing is the same as on the smaller model, so you lose nothing in terms of footprint.
