Negative Pressure Weighing RoomNegative pressure weighing room is a negative pressure purifying equipment designed for weighing raw auxiliary materials,Website: , 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.Standard size & parametersModelOverall sizeW×D×HWorking area sizeW×D×HUpstreamRated air velocity(m/s)Working area clean class（grade）Noise（dB）Illumination（Lx）Power(kW)LWR 12-120.60*1300×1200×25701200×600×20000.45±20%Same to background75 3000.3LWR 16-100.100*1600×1800×25701500×1200×20000.45LWR 24-120.120*2100×2700×25702000×2000×20000.6LWR 32-200.100*3100×2700×25703000×2000×20000.9LWR 48-120.1204100×3200×25704000×2500×20001.2Note: specifications listed in the table are only for customer’s reference.
