Screw compressor WALTER SF 18,5 KSP power input 18.5 kW, air delivery 1.1–3.2 m³/min at 8 bar, direct drive, inverter, 7-year warranty
Code: SF-18-5-KSP
Product detailed description
WALTER SF 18,5 KSP screw compressor with G 1″ connection
The 1,300 × 880 × 1,170 mm housing and G 1″ connection start in the SF KSP series precisely with the SF 18,5 KSP model. Smaller machines have a G ¾″ connection.
At 8 bar it delivers up to 3.2 m³/min, at 10 bar 3, and at 13 bar 2.6 m³/min. It weighs 378 kg and shares its housing with the SF 22 KSP, which is 40 kg heavier.
Configuration of this machine
- Single-stage screw airend · direct drive 1:1 · IE4 motor (IE5 optional) with inverter · submerged oil separator
- Three pressures: 8, 10 and 13 bar
- Housing shared with the SF 22 KSP, weight 378 kg
- G 1″ connection, noise level 64 dB(A)
- Power supply 400 V / 3 / 50 Hz, WALTER CONTROLLER control unit
Who it suits
For operations where 15 kW is no longer sufficient, but air consumption changes during a shift. The current increases gradually at startup, so the network is not loaded with current spikes.
When to choose a different model
Constant demand
If consumption does not fluctuate, the SK 18,5 KSP without an inverter is sufficient. It is in the same housing and, with fixed speed, delivers 3.2 m³/min at 8 bar, i.e. the same as the maximum air delivery of the SF 18,5 KSP.
More air
SF 22 KSP is in the same housing and at 8 bar delivers up to 4 m³/min. It weighs 418 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
- Does the SF 18,5 KSP have a two-stage sibling?
- No. The two-stage SF DSP series starts with the model SF 22 DSP.
- How much floor space does the machine need?
- The housing has a footprint of 1,300 × 880 mm and a height of 1,170 mm. Add free space for the cooling air intake and for servicing.
The machine comes with a 7-year warranty covering the entire machine. Warranty terms, maintenance, and a comparison of all 19 models can be found in the category Screw compressors WALTER SF KSP: inverter and direct drive.
Ventilek advises
The G 1″ connection is one size larger than on models up to 15 kW. Check that the existing air distribution system does not have a smaller diameter than the new connection.
