Air multiplier, utilizing technology from jet aircraft engines and car turbocharging, sucks in air through the bottom suction holes. The impeller hidden inside the edge of the circular ring sprays out the air in a circular trajectory. Due to the forced blowing out of the air, the amount of air passing through can be increased to 15 times the original amount.
