Cleanair®Powder Dispensing / Sampling booths are used in pharmaceutical manufacturing process to control the hazardous emissions of powders, dust during powder dispensing, product sampling, bag dispensing or weighing operation, etc., without risk to the operator or environment. The downdraught air prevents rising of airborne dusts / powder during weighing and dispensing operations into the operator’s breathing zone. The air forced downwards is extracted at lower level of the booth’s filtration system, where, dust particles are contained at multiple level of filtration prior to being re-circulated back into the booth’s air stream through 5 micron primary and 3 micron intermediate filters before supplying clean air to work area thru final H14 grade HEPA filters. Front opening of the dispensing booth are provided with transparent flexible strip curtain for easy movement of men and material.
