Automatic Anti Smoke Gun PM10 is used to spray water after connecting it with water tank mounted on a tower. It converts the water into a fine spray with droplets size of 20-10 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 small to medium properties like schools, hospitals, hotels, restaurant, banquets, farm houses, gardens etc. It basically works as rain to bring down the suspended particles present in the air. This device could be mounted any where and spray mist to settle all suspended particles. Anti smog gun for small areas can spray mist in 1200 sqmt area with the capacity of 30 litres per hr to bring down the polluted particles from the atmosphere
