Code: SKTG-11/500-KSP-COMBOProduct detailed description
WALTER SKTG 11/500 KSP COMBO screw compressor with direct drive and dryer
The SKTG 11/500 KSP COMBO adds a dryer and filters to the fixed-speed, direct-drive compressor, so the 500 l air tank, compressor and air treatment form a single assembly.
The machine delivers 1.65 m³/min at 8 bar and the dryer achieves a dew point of +3 °C. The weight of the assembly is 482 kg, 56 kg more than the version without a dryer.
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
- Dimensions 1,970 × 760 × 1,750 mm, weight 482 kg, G ¾″ connection
- Power supply 400 V / 3 / 50 Hz, WALTER CONTROLLER control unit



Who it suits
For continuous consumption of dry air in operations that do not want to assemble the dryer and filters separately. With fixed speed, the air delivery at each pressure is a single value: 1.65 m³/min at 8 bar and 1.12 m³/min at 13 bar.
When to choose a different model
With inverter
If consumption fluctuates, the SFTG 11/500 KSP COMBO is worth considering. It has the same power input, dryer and air tank, and weighs 487 kg.
Without dryer
The same housing, but without dryer and filters, is used by SKTG 11/500 KSP, which weighs 426 kg.
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
- How many compressors can the control unit manage?
- Up to 8 without a master controller. The compressor room can therefore be expanded in stages.
- Where to place the unit?
- On a floor that can bear 482 kg. Free space is needed around the unit so the machine has enough cooling air and so the coolers are easily accessible for servicing.
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’s advice
At a dew point of +3 °C, it is advisable to route the piping where the pipe temperature does not drop below this value.
