Code: SKTG-15/500-KSPProduct detailed description
WALTER SKTG 15/500 KSP screw compressor with fixed speed and an air delivery of 2.25 m³/min
The SKTG 15/500 KSP has the highest power input in the SKTG KSP range, 15 kW: with fixed speed it delivers 2.25 m³/min at 8 bar, 2.15 m³/min at 10 bar, and 2 m³/min at 13 bar.
At 13 bar, 89% of the air delivery from 8 bar is retained. Compared to the SKTG 11/500 KSP, it delivers 36% more air at 8 bar.
Configuration of this machine
- Direct drive 1:1 · large low-speed screw block · fixed speed
- Three pressures: 8, 10 and 13 bar
- Air tank 500 l, housing 1,970 × 725 × 1,750 mm, weight 429 kg
- Connection G ¾″, noise level 62 dB(A), service every 2,000 engine hours
- Power supply 400 V / 3 / 50 Hz, WALTER CONTROLLER control unit


Who it suits
For operation with higher but constant air consumption, where a simple design without an inverter is suitable. The control unit can control up to 8 compressors without a master controller, so the compressor room can be expanded with additional machines.
When to choose a different model
Consumption fluctuates
For variable consumption, with the same power input and an inverter, the SFTG 15/500 KSP is intended, which delivers up to 2.07 m³/min at 13 bar.
With dryer
The version with a dryer and filters is offered by the SKTG 15/500 KSP COMBO, which has the same dimensions and is 58 kg heavier.
What the parameters imply — calculated values
The values are calculated from the air delivery at 8 and 13 bar and serve to compare models with each other, not as a guaranteed figure.
Frequently asked questions
- Does the same machine exist without a tank?
- Yes, the SK 15 KSP. It weighs 244 kg and has a footprint of 1,090 × 730 mm; the assembly with a tank is 185 kg heavier.
