Sai/ Cyclones operate to collect relatively large size particulate matter from a gaseous Stream through the use of centrifugal forces. Dust laden gas in made to rotate in a decreasing pathway forcing solids to the outer edge of the gas stream for deposition into the bottom of the cyclone. efficiencies of 90% in particle sizes of 10 microns or greater are possible. Capacity as per requirement. Material of construction will be as per requirement.
