Screw Air Compressor with Booster System
...
The screw compressor with booster system is the economic and stable running options, especially for the air delivery between 4m3/min to 18m3/min, with less installation space,less noise, longer service life and more stable running than the high pressure piston compressor.
Air Pressure Booster Applications
High pressure screw compressors with air pressure boosters are used in a variety of industrial applications including:
- • Water and Electricity
- • PET Industry : PET Bottle Blowing
- • Leak Detection
- • Military and Other Fields
Why We Choose the Screw Compressor + Booster System?
For example, 12m3/min 40bar
