Buy from a device mainly used as an air pollution control device given to its ability to remove small or large particulate matter from the flow of gas. This device is known as cyclone dust separator. As the name implies, it separates dust from gases for the purpose of gas filtration. When a contaminated flue gas is fed into this device, it rotates at high speed in a spiral motion. The particles hit the inside wall and drops into collection hopper. Thus, all particles in the gas are collected at the bottom of the chamber. While the clean gas escapes from the top of the chamber.
