WALTER SKTG 5,5/300 SP COMBO Screw Compressor power input 5.5 kW, air delivery 0.85 m³/min at 8 bar, air tank 300 l, with dryer, belt drive, 7-year warranty
Code: SKTG-5-5/300-SP-COMBOProduct 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.
Configuration of this machine
- Low-speed screw block · belt drive with modern belt tensioning · fixed speed without inverter
- 300 l air tank, dryer and filters in the assembly
- Pressures 8, 10 and 13 bar
- Housing 1,683 × 739 × 1,629 mm, weight 369 kg
- Power supply 400 V / 3 / 50 Hz, WALTER CONTROLLER control unit



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
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.
