Forsberg’s Pneumatic Aspirators feature a floating cone designed to increase cleaning efficiency. Airwashing the incoming material prior to storage, eliminates unwanted foreign material in the bins (dust, chaff, pods, etc.).  The Pneumatic Aspirator has been designed to efficiently and quickly “airwash” dry granular products prior to screening, gravity, and destoning separations or to remove dust or light impurities and materials from heavier or good products. Since the Pneumatic Aspirator has virtually no moving parts, the machines require very little maintenance.
