Negative Pressure Weighing Room

Negative pressure weighing room is a negative pressure purifying equipment designed for weighing raw auxiliary materials, activated carbon and other dusty solids in purifying area. The weighing room work area is negative pressure relative to the background area. The vertical unidirectional flow within the work area makes the weighed dust sink along with the downward air flow, but not spread to the background area, thus preventing cross contamination, ensuring clean environment and protecting operator’s safety.
