WALTER SKTG 11/500 KSP fixed-speed screw compressor on an air receiver

SKTG 11/500 KSP is a fixed-speed screw compressor with 1:1 direct drive, mounted on a 500 l air receiver.

At 8 bar it delivers 1.65 m³/min, at 10 bar 1.5 m³/min and at 13 bar 1.12 m³/min. Despite a relatively low power input, it has a large low-speed screw block designed for economical and trouble-free operation for many years.

Who is it suitable for

For operation with constant air consumption, where an inverter would only bring a small saving and a simple design is sufficient. Steel oil and air piping and easy access to the coolers simplify maintenance and shorten service inspections.

When to choose a different model

Consumption varies during the day

With the same power input and an inverter, the SFTG 11/500 KSP is designed for this, delivering up to 1.3 m³/min at 13 bar compared to 1.12 m³/min for this model.

Dryer and filters

In the same housing, with the addition of a dryer and filters, there is the SKTG 11/500 KSP COMBO, which is 56 kg heavier.

What the parameters imply — calculated values

0.150m³/min air delivery per 1 kW power input at 8 bar
68%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.

Frequently asked questions

How often is service needed?
Every 2,000 engine hours. Regular maintenance is also a condition for the seven-year warranty.
How does it differ from the standalone SK 11 KSP?
The same machine without tank is SK 11 KSP. It weighs 244 kg and has a footprint of 1,090 × 730 mm, the SKTG 11/500 KSP with tank is 182 kg heavier.

The machine is covered by a 7-year warranty on the entire machine. Warranty conditions, maintenance, and a comparison of all 4 models can be found in the category WALTER SKTG KSP screw compressors: direct drive on the air receiver.

Ventilek advises

Fixed speed pays off where air consumption is constant. For fluctuating consumption, the model with inverter is more advantageous.
