Pneumatic-Driven Gas Boosters are powered by low-pressure gas at the large-area piston end to generate high-pressure fluid at the small-area piston end. Through the driving air pressure, the output air pressure can be adjusted steplessly to compress air and other gases.Simple maintenance: Pneumatic booster pumps have few parts and seals, which makes maintenance simple and inexpensive.
