Working Principle

Under the effect of the air fan,air flow with dust is sucked into the dust collecting chamber from the bottom or one side. For those big dust particles, they will go downwards because of the decreasing speed of the air flow.While, for those fine dust particles,they will be stopped to the outside layer of the filter bag. When compressed air blow reverse back the filter bag, the fine particles will break away from the bag and go downwards with the big particles. Finally, dust particles will be discharged outside and the purified air will be discharged upon the upper side of the cleaning chamber. Finally, it plays the role of collecting dust, air pollution prevention purpose.
