Cyclone Air Pollution Control System is available in mild steel and in stainless steel for corrosive and sticky particulate separation and for highly abrasive dust; the inner surface is lined with wear resistant material to increase life. The System has low separation efficiency and is not recommended as an individual final air cleaning device for fine dusts. The System is made using cyclones with a common header for dust in and dust out. The Cyclone Air Pollution Control System has the feature that the collected dust is delivered into containers through airlock devices such as rotary valves, double flap valves or plain slide gates.
