WALTER SK 11 KSP Screw Compressor power input 11 kW, air delivery 1.65 m³/min at 8 bar, direct drive, fixed speed, 7-year warranty
Code: SK-11-KSP
Product detailed description
WALTER SK 11 KSP screw compressor with direct drive and fixed speed
The SK 11 KSP is the entry-level model in the SK KSP range: the screw block is connected directly to the motor and the machine runs at fixed speed, without an inverter. At 8 bar it delivers 1.65 m³/min, at 10 bar 1.5, and at 13 bar 1.12 m³/min.
The 1,090 × 730 × 1,080 mm housing is shared with the SK 15 KSP. At 244 kg, it is among the lightest machines in the range along with the SK 15 KSP, and the 62 dB(A) noise level is the lowest in the entire range.
Configuration of this machine
- Screw element coupled directly to the motor · fixed speed without inverter · three-stage oil separation
- Air delivery of 1.65 m³/min at 8 bar, 1.5 at 10 bar and 1.12 at 13 bar
- Housing 1,090 × 730 × 1,080 mm shared with SK 15 KSP, weight 244 kg
- G ¾″ connection, noise level 62 dB(A) — the lowest in the range
- Power supply 400 V / 3 / 50 Hz, WALTER CONTROLLER control unit
Who it suits
For a smaller operation or workshop where air is drawn by one or two consumers and consumption doesn't change much during a shift. Fixed speed is a simpler solution than a machine with an inverter for such steady demand.
When to choose a different model
Need more air
In the same housing and with the same weight of 244 kg, the SK 15 KSP delivers more air. At 8 bar it is 2.25 m³/min, i.e. 36% more.
Consumption fluctuates
For variable consumption, the model with an inverter of the same input power, the SF 11 KSP, is suitable. It has the same housing (1,090 × 730 × 1,080 mm) and the air delivery at 8 bar is continuously regulated in the range of 0.67–1.65 m³/min.
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 SK 11 KSP also available with an air tank?
- Yes. The ready-made assembly on a 500 l air tank is called SKTG 11/500 KSP, the COMBO version additionally includes a dryer. The air delivery and noise level of 62 dB(A) remain the same (1.65 m³/min at 8 bar).
- How loud is the SK 11 KSP?
- 62 dB(A), the lowest of all models in the range. The value is stated with a tolerance of ±3 dB.
The machine is covered by a 7-year warranty on the entire machine. Warranty conditions, maintenance, and a comparison of all 17 models can be found in the category WALTER SK KSP screw compressors: direct drive without losses.
Ventilek advises
Before choosing between fixed speed and an inverter, one measurement is enough: how air consumption varies during a single shift.
