1. Store the air compressed by the screw air compressor;
2. Buffer pressure, because the pressure of the air discharged from the screw air compressor fluctuates to a certain extent, after installing the air storage tank, the compressed air pressure at the air end can be more stable.
3. Pre-dewatering. Part of the water vapor in the air has been compressed by the screw air compressor to form liquid water droplets. Most of these water droplets will be deposited on the bottom of the gas storage tank when they pass through the gas storage tank. There is a drain valve at the bottom of the gas storage tank. It can be discharged manually or automatically.
