Code: SKTG-5-5/500-SPProduct detailed description
WALTER SKTG 5,5/500 SP screw compressor with the largest air receiver in the range
The SKTG 5,5/500 SP carries the largest air receiver in the range, 500 l, while still keeping the power input at 5.5 kW. At 8 bar it delivers 0.85 m³/min, and the whole unit weighs 350 kg.
The large tank evens out demand peaks, so the machine does not have to react to every short increase in consumption. The housing, 1,970 × 720 × 1,700 mm, is the longest in the range.
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, weight 350 kg

Who it suits
Suitable for operations with fluctuating demand, where several tools work alternately and short, strong peaks occur. With even demand, the air reserve is not used and a smaller tank is sufficient.
