Code: SKTG-7-5/500-SP
Product detailed description
WALTER SKTG 7,5/500 SP screw compressor on a 500 l air tank
SKTG 7,5/500 SP combines the highest power input in the range, 7.5 kW, with the largest air tank, 500 l. At 8 bar it delivers 1.15 m³/min, at 10 bar 1 m³/min, and at 13 bar 0.85 m³/min.
The belt drive with fixed speed is paired with an air reserve that evens out demand peaks. The unit weighs 370 kg and the housing measures 1,970 × 720 × 1,700 mm.
Configuration of this machine
- Low-speed screw block · belt drive with modern belt tensioning · fixed speed without inverter
- 500 l air tank, the largest in the range
- Pressures 8, 10 and 13 bar
- Housing 1,970 × 720 × 1,700 mm, the same as the COMBO version
- Power supply 400 V / 3 / 50 Hz, WALTER CONTROLLER control unit
Who it suits
For permanently higher air consumption, where several tools are used alternately and a large reserve is needed. The version without a dryer assumes a distribution system where you handle the dryer and filters separately.
When to choose a different model
Dryer and filters
The same machine with a dryer and filters is the SKTG 7,5/500 SP COMBO. It weighs 51 kg more.
Inverter and direct drive
On the 500 l air tank there is also the SFTG 7,5/500 KSP. It has an inverter and direct drive, weighs 383 kg, and at 8 bar delivers 0.42–1.15 m³/min.
What the parameters imply — calculated values
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
- Is SKTG 7,5/500 SP or SFTG 7,5/500 KSP better?
- It depends on the consumption. The maximum air delivery at 8 bar is the same, 1.15 m³/min, but the SFTG regulates it continuously, while the SKTG runs at a fixed speed. For fluctuating consumption, the inverter is suitable; for constant consumption, a fixed speed is sufficient.
- Is the same output available without a tank?
- Yes, the standalone unit without tank is the SK 7,5 SP, weighing 240 kg. At 8 bar it delivers the same 1.15 m³/min.
This machine is covered by a 7-year warranty on the entire unit. Warranty conditions, maintenance, and a comparison of all 12 models can be found in the category Screw compressors WALTER SKTG SP and SK SP: belt drive.
Ventilek’s tip
Without a dryer, moisture in the compressed air must be expected. For distribution systems sensitive to moisture, the COMBO version is more suitable.
