WALTER SLC 22/16 Screw Compressor input power 22 kW, air delivery 1.2–2.4 m³/min at 16 bar, inverter, for laser cutting, 7-year warranty
Code: SLC-22/16
Product detailed description
WALTER SLC 22/16 screw compressor at 16 bar with inverter
The SLC 22/16 is a standalone compressor from the Laser Cut range for 16 bar pressure, whose air delivery at this pressure ranges from 1.2–2.4 m³/min.
The range is created by the inverter continuously adjusting the speed according to demand. The machine has no air tank or dryer, these are sized separately.
Configuration of this machine
- The inverter continuously varies the speed
- Standalone machine without air tank and dryer, 16 bar pressure
- Weight 550 kg, noise level 64 dB(A)
- G 1″ connection, housing shared with SLC 22/20
- Power supply 400 V / 3 / 50 Hz, WALTER CONTROLLER control unit
Who it suits
It works well for laser cutting with higher air demand than a tank-based assembly can supply: at 16 bar it reaches up to 2.4 m³/min compared to 1.3 m³/min for the SLCTG 15/16 COMBO. The air tank and air treatment are selected according to the cutter and operation.
When to choose a different model
Higher pressure
For 20 bar pressure, the SLC 22/20 is intended. Its maximum air delivery is 1.7 m³/min, i.e. 29% lower than this model.
Complete unit with dryer
The SLCTG 15/16 COMBO offers an assembly with air tank, dryer and five filters. At 16 bar it delivers 1.3 m³/min and weighs 510 kg.
What the parameters imply — calculated values
The values are calculated from the maximum air delivery at the machine's working pressure and serve to compare models with each other, not as a guaranteed figure.
Frequently asked questions
- Why is the air delivery given as a range?
- The inverter continuously adjusts the speed according to demand. At the lowest speed, the machine delivers 1.2 m³/min, at the highest speed 2.4 m³/min.
- How does it differ from a standard 22 kW screw compressor?
- SF 22 KSP has the same input power, designed for pressures of 8, 10 and 13 bar. At 13 bar it delivers up to 3.3 m³/min, while SLC 22/16 at 16 bar delivers up to 2.4 m³/min: higher pressure means lower air delivery at the same input power.
The machine is covered by a 7-year warranty on the entire machine. Warranty conditions, maintenance, and a comparison of all 3 models can be found in the category Screw compressors WALTER SLC Laser Cut: 16 and 20 bar.
Ventilek advises
An air delivery range of 1.2–2.4 m³/min means the machine can cover demand that varies significantly during operation. Nevertheless, the air receiver and dryer still need to be sized in advance.
