The negative pressure weighing room is composed of working area, return air box, fan box, air outlet box, external box, air supply high efficiency filter, air exhaust high efficiency filter, variable air volume fan unit, PLC control system and sensor system. The control panel is located in the front of the working area inside the equipment. The control panel adopts the touch screen control panel, which can control the start and stop of the fan, adjust the working condition of the fan, and adjust the required wind speed in the working area. There is a differential pressure gauge beside it to test the resistance of the filter. There is an exhaust regulating board in the air supply box, which can adjust the exhaust air volume of the equipment within a reasonable range.
