Code: SKTG-15/500-KSP-COMBOProduct detailed description
WALTER SKTG 15/500 KSP COMBO fixed-speed screw compressor with dryer
SKTG 15/500 KSP COMBO is the most powerful assembly in the SKTG KSP range: it adds a dryer with a +3 °C dew point and filters to the fixed-speed compressor with a 500 l air tank.
The assembly weighs 487 kg, 58 kg more than the version without the dryer, while the dimensions of 1,970 × 725 × 1,750 mm remain the same. At 8 bar it delivers 2.25 m³/min, at 13 bar 2 m³/min.
Configuration of this machine
- Direct drive 1:1 · large low-speed screw block · fixed speed
- Three pressures: 8, 10 and 13 bar
- Dryer and filters included in the assembly, dew point +3 °C
- Connection G ¾″, noise level 62 dB(A), service every 2,000 operating hours
- Power supply 400 V / 3 / 50 Hz, WALTER CONTROLLER control unit



Who it suits
For operations with higher but constant consumption of dry air that don't want to combine a dryer and filters separately. With a 15 kW input power, it is the assembly with the highest air delivery at all three pressures in the SKTG KSP range.
When to choose a different model
With inverter
For fluctuating consumption, the SFTG 15/500 KSP COMBO is intended, with the same input power, dryer and air tank, weighing 492 kg.
Without dryer
If you dry the air elsewhere, the SKTG 15/500 KSP, which is 58 kg lighter, is sufficient.
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
- What air delivery does the machine provide at individual pressures?
- At fixed speed, the air delivery is a single value at each pressure: 2.25 m³/min at 8 bar, 2.15 m³/min at 10 bar and 2 m³/min at 13 bar.
- How is it maintained?
- Service is required every 2,000 engine hours. Maintenance is simplified by steel oil and air piping and easy access to the coolers.
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
At 487 kg, this is the heaviest assembly in the SKTG KSP range, so it is advisable to check the floor and the method of transport into the machine room.
