WALTER SFTG 15/500 KSP COMBO screw compressor: the heaviest configuration in the range

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

0.150m³/min air delivery per 1 kW power input at 8 bar
41%of the maximum air delivery at 8 bar is delivered by the machine at the lowest speed

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.
