Code: SF-11-KSP
Product detailed description
WALTER SF 11 KSP screw compressor with submerged oil separator
SF 11 KSP is the first model in the range with a submerged oil separator with a long service life. The smaller models SF 5,5 KSP and SF 7,5 KSP have a screw-in separator.
At 8 bar it delivers 0.67–1.65 m³/min and weighs 243 kg. The housing 1,090 × 730 × 1,080 mm is shared with the SF 15 KSP, the G ¾″ connection is the same as on the smallest models.
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 15 KSP, weight 243 kg
- Connection G ¾″, noise level 62 dB(A)
- Power supply 400 V / 3 / 50 Hz, WALTER CONTROLLER control unit
Who it suits
For a smaller operation that has outgrown the smallest housing, but air consumption still fluctuates. At the lowest speed, the machine still delivers 41% of the maximum air delivery at 8 bar.
When to choose a different model
Constant consumption
If consumption does not fluctuate during the shift, the SK 11 KSP without an inverter is sufficient. With a fixed speed, it delivers 1.65 m³/min at 8 bar and weighs 244 kg.
More air
The SF 15 KSP is in the same housing and delivers up to 2.25 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
- How does the oil separator differ from the smaller models?
- Models up to 7.5 kW have a screw-type separator, which is easy to operate. From the SF 11 KSP onwards, it is a highly efficient immersion separator with a long service life.
- Can the machine be retrofitted with a tank?
- Yes, optionally with an air receiver and/or a dryer. The ready-made set with a 500 l air tank is the SFTG 11/500 KSP.
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
Around the 1,090 × 730 mm housing, leave free space for the cooling air intake and for servicing, which is repeated every 2,000 motor hours.
