An smog gun is used to spray water after connecting it with water tank mounted on a vehicle. It converts the water into a fine spray with droplets size of 50-100 microns by passing it at high pressure through propellers.The idea behind this invention is to reduce air pollution by binding dust and other particulate matter and carrying them down to the ground level along with water. This is been designed for the arid places and the metropolitan areas. It basically works as rain to bring down the suspended particles present in the air. This device could be taken across the city to spray water to settle all suspended particles. An smog gun can spray water up to the height of 150 feet with the capacity of 30-100 litres per minute to bring down the polluted particles from the atmosphere.
