Product detailed description
Two-stage screw compressor WALTER SF 90 DSP with DN 65 connection
SF 90 DSP opens the large housing 2,656 × 1,698 × 1,800 mm, which it shares with the 110 and 132 kW models, and has the first DN 65 connection in the series. At 8 bar it delivers up to 19.1 m³/min, at 10 bar 16.76, and at 13 bar 14.34 m³/min.
The single-stage SF 90 KSP delivers 16 m³/min at 8 bar, the two-stage SF 90 DSP 19% more.
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 SF 110 DSP and SF 132 DSP, weight 3,300 kg
- DN 65 connection, noise level 70 dB(A)
- Power supply 400 V / 3 / 50 Hz, WALTER CONTROLLER control unit
Who it suits
For industrial operation with continuous consumption of tens of kilowatts, where a single-stage machine is at its limit. The more powerful model from the same housing fits on the same footprint.
When to choose a different model
Lower output
SF 75 DSP delivers up to 15.7 m³/min at 8 bar in a smaller housing (2,256 × 1,469 × 1,700 mm, 1,861 kg).
Higher output
SF 110 DSP is in the same housing and delivers up to 23.2 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
- What is the regulation range at 13 bar?
- 5.736–14.34 m³/min.
- How much does the machine weigh?
- 3,300 kg. Make sure the plant room floor has adequate load-bearing capacity.
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 advises
Three models in the same housing — 90, 110, and 132 kW. Choose based on consumption, not input power: what matters is the air delivery within the regulation range.
