Product detailed description

Screw compressor WALTER SKTG 5,5/300 SP COMBO with dryer on a medium tank

The SKTG 5,5/300 SP COMBO carries a dryer and filters on a 300 l air tank and weighs 369 kg, i.e. 13 kg less than the COMBO with a 500 l tank. Air delivery drops with pressure from 0.85 m³/min at 8 bar to 0.55 m³/min at 13 bar.

Compared to the model without a dryer, 43 kg is added, while the housing 1,683 × 739 × 1,629 mm remains the same. The drive is still belt-driven, with fixed speed and without an inverter.

Who it suits

It makes sense in a workshop that needs dried and filtered air from the machine, but does not have space for a housing 1,970 mm long. The air supply is smaller than with the COMBO with a 500 l tank, but the machine's air delivery is the same.

When to choose a different model

Without dryer

The same machine without a dryer and filters is the SKTG 5,5/300 SP. It weighs 326 kg, i.e. 43 kg less.

Larger air supply

The assembly with a 500 l tank, i.e. 200 l larger, is offered by the SKTG 5,5/500 SP COMBO. It weighs 382 kg.

What the parameters imply — calculated values

0.155m³/min of air delivery per 1 kW of power input at 8 bar
65%of the air delivery at 8 bar remains at a pressure of 13 bar

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 there the same machine with an inverter?
Built on the same tank with a dryer is the SFTG 5,5/300 KSP COMBO, which has an inverter and direct drive. At 8 bar it delivers in the range of 0.42–0.95 m³/min.
How does the housing differ from the COMBO with a 500 l tank?
It is 287 mm shorter and 71 mm lower, but 19 mm wider: 1,683 × 739 × 1,629 mm versus 1,970 × 720 × 1,700 mm.

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 advises

Compared to the COMBO with a 500 l tank, the air supply decreases by 200 l, but the housing is 287 mm shorter. When choosing, it is worth considering what is scarcer in the workshop: space, or air supply.
