Who it suits
It suits applications where higher output is needed, but the space does not allow for a housing 1,970 mm long. The air supply is smaller than with the largest tank, but larger than with the smallest.
When to choose a different model
Largest air supply
A 500 l tank, i.e. 200 l larger, with the same power input is offered by the SKTG 7,5/500 SP. It weighs 370 kg.
Weaker machine
A power input of 5.5 kW on the same tank is offered by the SKTG 5,5/300 SP, which delivers 0.85 m³/min at 8 bar.
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
- Does the SKTG 7,5/300 SP deliver the same amount of air as the model with a 500 l tank?
- Yes, at 8 bar both models deliver 1.15 m³/min, at 10 bar 1 m³/min, and at 13 bar 0.85 m³/min. The air reserve and housing dimensions differ.
- Is there the same machine with a dryer?
- Yes, the dryer and filters are included in the SKTG 7,5/300 SP COMBO version. With the same tank and housing, it adds 43 kg.
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
The machine is shorter, but 19 mm wider than the model with a 500 l tank. When passing through a tight space, it is advisable to measure the width as well, not just the length.
