Code: SFTG-15/500-KSP-COMBOProduct detailed description
WALTER SFTG 15/500 KSP COMBO screw compressor: the heaviest configuration in the range
The SFTG 15/500 KSP COMBO is the most powerful and at the same time the heaviest configuration in the SFTG KSP range: the compressor with inverter, 500 l air tank, dryer and filters together weigh 492 kg.
At 8 bar it delivers up to 2.25 m³/min, at 13 bar up to 2.07 m³/min. The dryer's dew point is +3 °C, and the dimensions of 1,970 × 760 × 1,750 mm are the same as for the version without a dryer.
Configuration of this machine
- Direct drive 1:1 · IE4 magnetic motor (IE5 optional) · inverter
- Three pressures: 8, 10 and 13 bar
- Dryer and filters included in the assembly, dew point +3 °C
- G ¾″ connection, noise level 62 dB(A), submerged oil separator
- Power supply 400 V / 3 / 50 Hz, WALTER CONTROLLER control unit



Who it suits
For operation with higher consumption of dried air and several outlet points. The dryer with filters and the 500 l air tank are part of a single unit, and the compressor with inverter adjusts the speed to demand. At 8 bar it delivers 36% more air than the SFTG 11/500 KSP COMBO in the same housing.
When to choose a different model
Without dryer
If you dry the air elsewhere, the SFTG 15/500 KSP in the same housing will serve the purpose.
Fixed speed
Fixed speed at the same power input and with a dryer is offered by the SKTG 15/500 KSP COMBO, which weighs 487 kg.
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 heavier is it than the version without a dryer?
- By 60 kg: 492 kg versus 432 kg. The dimensions of 1,970 × 760 × 1,750 mm remain the same.
- Is the COMBO assembly louder than the model without a dryer?
- No. The noise level of 62 dB(A) with a tolerance of ±3 dB(A) is the same as for the version without a dryer.
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
For this model, the air delivery at 13 bar drops by only 8% compared to 8 bar, so even tools requiring higher pressure do not require choosing a larger machine.
