WALTER SKTG 5,5/270 SP Screw Compressor power input 5.5 kW, air delivery 0.85 m³/min at 8 bar, air tank 270 l, belt drive, 7-year warranty
Code: SKTG-5-5/270-SPProduct detailed description
WALTER SKTG 5,5/270 SP screw compressor with the smallest air receiver in the range
The SKTG 5,5/270 SP combines a compressor with the smallest air receiver in the range, which holds 270 l. The unit weighs 300 kg and delivers 0.85 m³/min at 8 bar.
The machine is built directly onto the tank, so it does not need to be assembled from individual parts, and it takes up a footprint of 1,120 × 720 mm. The belt drive with fixed speed is simple to operate, and servicing is carried out every 2,000 engine hours.
Configuration of this machine
- Low-speed screw block · belt drive with modern belt tensioning · fixed speed without inverter
- 270 l air receiver, the smallest in the range
- Pressures 8, 10 and 13 bar, G ¾″ connection
- Housing 1,120 × 720 × 1,710 mm, weight 300 kg
- Power supply 400 V / 3 / 50 Hz, WALTER CONTROLLER control unit


Who is it suitable for
For a small workshop where tools are not all used at the same time and air is drawn off evenly. For short but strong demand peaks, it is wiser to choose a larger air receiver.
When to choose a different model
Larger air supply
The same power input with a 300 l tank is offered by the SKTG 5,5/300 SP. It weighs 26 kg more than this model.
Inverter and direct drive
The SFTG 5,5/270 KSP is also built on an equally large tank. It has an inverter and direct drive, delivering 0.42–0.95 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
- What air receivers does the range offer?
- The tanks come in 270, 300, or 500 l. Weight increases with volume: 300 kg for this tank, 326 kg for the larger one, and 350 kg for the largest.
- What types of operations is this range designed for?
- For small and medium-sized operations, where safe and economical air production matters. Simple and quick maintenance means more time for work and less for servicing.
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
A smaller tank empties sooner under heavy draw-off than a larger one, but the housing is 850 mm shorter than with the 500 l tank. Before choosing, it is worth checking how long the most demanding tool draws air for.
