Screw compressor WALTER SFTG 5,5/500 KSP COMBO input power 5.5 kW, air delivery 0.42–0.95 m³/min at 8 bar, air tank 500 l, with dryer, inverter, 7-year warranty
Code: SFTG-5-5/500-KSP-COMBO
Product detailed description
WALTER SFTG 5,5/500 KSP COMBO screw compressor: dryer and 500 l air tank in one unit
The COMBO version adds a dryer and filters to the SFTG 5,5/500 KSP, so the compressor, 500 l air tank, and air treatment form one assembly.
The dryer and filters add 32 kg, the whole assembly weighs 395 kg. At 8 bar, the unit delivers up to 0.95 m³/min, the dryer's dew point is +3 °C.
Configuration of this machine
- Direct drive 1:1 · IE4 magnetic motor (IE5 optional) · inverter
- Three pressures: 8, 10 and 13 bar
- Dryer and filters included in the assembly, dew point +3 °C
- Housing 1,970 × 720 × 1,700 mm, weight 395 kg, connection G ¾″
- Power supply 400 V / 3 / 50 Hz, WALTER CONTROLLER control unit
Who it suits
For a smaller operation with intermittent demand that also needs dried air. The large tank evens out peaks and the dryer with filters treats the air before it enters the distribution system. At 395 kg, this is the heaviest 5.5 kW model in the range, which is worth considering when it comes to the floor.
When to choose a different model
Without dryer
If you dry the air elsewhere in the distribution system, the SFTG 5,5/500 KSP is sufficient. It has the same dimensions and weighs 363 kg.
Belt drive
Belt drive and fixed speed with the same tank, dryer, and housing are offered by the SKTG 5,5/500 SP COMBO, which delivers 0.85 m³/min at 8 bar and 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 the COMBO assembly larger than the model without a dryer?
- No. The dimensions 1,970 × 720 × 1,700 mm are the same, only the weight increases.
- What happens to the air in the COMBO assembly?
- Compressed air passes through the dryer to a dew point of +3 °C and through filters, so it leaves the system conditioned.
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
At 13 bar, this model delivers up to 0.64 m³/min, i.e. 67% of the air delivery at 8 bar. For tools requiring higher pressure, it is worth comparing the 7.5 kW model.
