Product 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.
