Product detailed description
WALTER SFTG 15/500 KSP screw compressor: the most powerful model in the SFTG KSP range
The SFTG 15/500 KSP is the most powerful model in the SFTG KSP range: at 8 bar it delivers up to 2.25 m³/min, at 10 bar up to 2.15 m³/min, and at 13 bar up to 2.07 m³/min.
At 13 bar, 92% of the air delivery at 8 bar is retained, which is the highest of all models in the range. The housing dimensions of 1,970 × 760 × 1,750 mm are the same as those of the SFTG 11/500 KSP.
Configuration of this machine
- Direct drive 1:1 · IE4 magnetic motor (IE5 optional) · inverter
- Three pressures: 8, 10 and 13 bar
- 500 l air tank, housing 1,970 × 760 × 1,750 mm, weight 432 kg
- G ¾″ connection, noise level 62 dB(A), submerged oil separator
- Power supply 400 V / 3 / 50 Hz, WALTER CONTROLLER control unit
Who it's suitable for
For operations with higher air consumption and several outlet points, where an input power of 11 kW is no longer sufficient. The 500 l air tank evens out short peaks, and the inverter maintains pressure even with fluctuating consumption. At 8 bar, it delivers 36% more than the SFTG 11/500 KSP.
When to choose a different model
With dryer
The version with dryer and filters is the SFTG 15/500 KSP COMBO, which is 60 kg heavier.
Fixed speed
With the same input power and air tank, but with fixed speed, is the SKTG 15/500 KSP, which delivers 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 much does it weigh compared to the standalone SF 15 KSP?
- The version without tank with the same air delivery is SF 15 KSP. It weighs 243 kg and has a footprint of 1,090 × 730 mm; the version mounted on the air receiver is heavier by 189 kg.
- What is the control range at 8 bar?
- From 0.92 to 2.25 m³/min. The inverter continuously adjusts the output according to demand, so the machine does not have to run at full power during lower demand.
The machine is covered by a 7-year warranty on the whole machine. Warranty conditions, maintenance and a comparison of all 14 models can be found in the category Screw compressors WALTER SFTG KSP: with inverter on the air receiver.
Ventilek advises
The most powerful model sits on the same cabinet as the 11 kW model, so when planning the compressor room the footprint does not change and only the demand matters.
