Negative Pressure Weighing Room is a localized purification equipment used exclusively in pharmaceutical, microbiological research and scientific experiments, etc. It provides a vertical unidirectional airflow. Part of the clean air is circulated in the working area and part is discharged to the neighboring area, resulting in negative pressure in the working area. Weighing and dispensing of dust and reagents in the equipment can control the spillage and uplift of dust and reagents, prevent the inhalation hazards of dust and reagents to human beings, and also avoid the cross-pollution of dust and reagents, and protect the external environment and the safety of indoor personnel.
Decheng TECHNOLOGY Negative Pressure Weighing Bench|Negative Pressure Weighing Bench Features.
| The fan has a long life, low noise, maintenance-free and low vibration;. | Double-layer negative pressure structure, no risk of leakage. | Excellent air distribution properties. |
| Automatic constant or stepwise adjustment of wind speed. | Liquid tank design ensures perfect sealing. | Consistent and clean inside and out. |
Negative pressure weighing room is composed of working area, return air box, fan box, air outlet box, outer box, high efficiency filter for air supply, high efficiency filter for air exhaust, PLC control system of variable air volume fan set and sensing system and other major components. The control panel is located in the front of the working area inside the equipment, and the control panel adopts the touch screen type control panel, which can control the starting and stopping of the fan, adjust the working condition of the fan, and adjust the wind speed needed in the working area. There is a differential pressure meter next to it to test the resistance of the filter, and there is also an exhaust air adjustment board inside the air supply box to adjust the exhaust air volume of the equipment within a reasonable range.
