OTFXH Series Air-recycling Aspirators are widely used for the separation of low-density particles from granular products such as wheat, barley, paddy,oilseed and corn in cereals, oils and foodstuff process-ing plants. Due to air recycling, only a small fresh airvolume is required for aspirating and the dedust system is equipped by itself, both of which make it a ener-gy-saving and environmentally-sound machine.
