Screw compressor WALTER SKTG 7,5/270 SP input power 7.5 kW, air delivery 1.15 m³/min at 8 bar, air tank 270 l, belt drive, 7-year warranty
Code: SKTG-7-5/270-SP
Product detailed description
WALTER SKTG 7,5/270 SP screw compressor on a 270 l air receiver
The SKTG 7,5/270 SP delivers a power input of 7.5 kW into the smallest air receiver in the range, which holds 270 l. At 8 bar it delivers 1.15 m³/min, i.e. 35% more than the SKTG 5,5/270 SP.
The housing of 1,120 × 720 × 1,710 mm is the same as that of the weaker model on the same tank, with a weight of 320 kg being only 20 kg higher. The compressor is mounted directly on the air receiver and operates at fixed speed.
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 320 kg
- Power supply 400 V / 3 / 50 Hz, WALTER CONTROLLER control unit
Who it suits
It is suitable where air consumption is higher, but space for the air receiver is limited. A small tank is not a problem where consumption is steady and close to the machine's air delivery.
When to choose a different model
Lower power input
The same tank with a power input of 5.5 kW is used by the SKTG 5,5/270 SP. It weighs 300 kg and delivers 0.85 m³/min at 8 bar.
Larger air receiver
With the same power input and a larger tank, 300 l, the SKTG 7,5/300 SP is available.
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 pressures is the machine offered for?
- For 8, 10 and 13 bar. As pressure increases, air delivery decreases: 1.15 m³/min at 8 bar, 1 m³/min at 10 bar and 0.85 m³/min at 13 bar.
- Is there the same machine with an inverter?
- Built on the same tank is the SFTG 7,5/270 KSP, which has an inverter and direct drive. At 8 bar it delivers in the range of 0.42–1.15 m³/min.
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
Tank size does not change the machine's output: at 8 bar, all models in the range with a 7.5 kW power input deliver the same 1.15 m³/min. The air receiver volume is therefore determined by consumption peaks, not by air delivery.
