For safety, some dust collection applications require isolation of the collected dust from contact with workers. This may be from processes involving pharmaceutical dust like table presses, table coating, fluid bed drying, spray drying, blending, granulation and especially general room ventilation. Containment dust collectors have special features and methods to replace the dirty filter cartridges and dispose of the collected, potent/hazardous dust being discharged. This video demonstrates these safe-change methods:
As you see, the cartridge filters are safely replaced by a two-person crew with the bag-in/bag-out (BIBO) safe-change replacement system. At the discharge of the colletor, the dust is contained within a continuous liner. For more information go to Dust Collection for Pharmaceutical Solid Dosage Manufacturing.
