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

0.150m³/min air delivery per 1 kW power input at 8 bar
89%of air delivery at 8 bar remains at a pressure of 13 bar

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.
