Code: SFTG-5-5/300-KSP
Product detailed description
WALTER SFTG 5,5/300 KSP screw compressor with inverter and 300 l air receiver
SFTG 5,5/300 KSP is a compressor with inverter on a medium-sized air receiver: the unit 1,683 × 739 × 1,629 mm is 403 mm longer than with the 270 l tank and 287 mm shorter than with the 500 l tank.
At 8 bar it delivers up to 0.95 m³/min, at 13 bar up to 0.64 m³/min. The SFTG 7,5/300 KSP with higher power input has the same housing and the same weight of 326 kg.
Configuration of this machine
- Direct drive 1:1 · IE4 magnetic motor (IE5 optional) · inverter
- Three pressures: 8, 10 and 13 bar
- 300 l air receiver, assembly 1,683 × 739 × 1,629 mm, weight 326 kg
- G ¾″ connection, noise level 60 dB(A), control range at 10 bar 0.36–0.8 m³/min
- Power supply 400 V / 3 / 50 Hz, WALTER CONTROLLER control unit
Who is it suitable for
For a workshop with several outlets where air consumption varies during the day and the air tank evens out short peaks. The inverter adjusts the speed to the demand, so the machine only produces as much air as is currently being drawn off. The 300 l tank is suitable where 270 l is already too little and 500 l would take up unnecessary space.
When to choose a different model
Dry air from a single unit
With a dryer and filters as part of the assembly, the SFTG 5,5/300 KSP COMBO is intended for this purpose, which has the same dimensions and weighs 43 kg more.
Larger air supply
The 500 l air receiver is used on the SFTG 5,5/500 KSP. The unit is longer (1,970 mm) and weighs 363 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
- How does it differ from the belt-driven model?
- The same air receiver, but with belt drive and fixed speed, is used on the SKTG 5,5/300 SP. At 8 bar it delivers 0.85 m³/min, while the SFTG 5,5/300 KSP delivers up to 0.95 m³/min, i.e. 12% more.
- How wide is the control range?
- At 8 bar from 0.42 to 0.95 m³/min, at 13 bar from 0.36 to 0.64 m³/min. Within this range, the output changes continuously according to demand.
The machine is covered by a 7-year warranty on the whole machine. Warranty conditions, maintenance and a comparison of all 14 models can be found in the category Screw compressors WALTER SFTG KSP: with inverter on the air receiver.
Ventilek advises
The 300 l air tank provides a medium air supply for a medium-length assembly. If dry air is required, the COMBO version has the same housing.
