Product detailed description
WALTER SK 18,5 KSP screw compressor with G 1″ connection
The SK 18,5 KSP is the first model in the SK KSP range with a G 1″ connection and a housing with a footprint of 1,300 × 880 mm. At 8 bar it delivers 3.2 m³/min, at 10 bar 3, and at 13 bar 2.2 m³/min.
The housing is shared with the SK 22 KSP, which it is 40 kg lighter than (378 kg vs. 418 kg). Both models have the same noise level of 64 dB(A).
Configuration of this machine
- Screw element coupled directly to the motor · fixed speed without inverter · three-stage oil separation
- Air delivery of 3.2 m³/min at 8 bar, 3 at 10 bar, and 2.2 at 13 bar
- Housing 1,300 × 880 × 1,170 mm shared with the SK 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 that have outgrown the smallest housing in the range. The connection here increases from G ¾″ to G 1″, which needs to be taken into account when connecting to an existing distribution system.
When to choose a different model
More air in the same cabinet
The SK 22 KSP is housed in the same housing. At 8 bar it delivers 4 m³/min, i.e. 25% more, and weighs 418 kg.
Fluctuating consumption
The SF 18,5 KSP has the same power input with an inverter. The housing of 1,300 × 880 × 1,170 mm and weight of 378 kg are the same, while air delivery at 8 bar is continuously regulated within the range of 1.1–3.2 m³/min.
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 connection does the SK 18,5 KSP have?
- G 1″. The smaller models SK 11 KSP and SK 15 KSP have G ¾″, from SK 30 KSP upwards it is G 1½″.
- How much oil remains in the compressed air?
- Three-stage separation keeps the oil mist content in the outlet air at a maximum of 3 ppm.
The machine is covered by a 7-year warranty on the entire machine. Warranty conditions, maintenance, and a comparison of all 17 models can be found in the category WALTER SK KSP screw compressors: direct drive without losses.
Ventilek advises
This housing contains two models, 18.5 and 22 kW. This means the compressor room layout can be planned before it is clear which output will ultimately be sufficient.
