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.
Why We Choose the Screw Compressor + Booster System?
For example, 12m3/min 40bar
