Negative Pressure Weighing Room

working principle:
The small amount of dust generated during operation in the negative pressure weighing room is first filtered by the primary and intermediate filters, and then sent to the high-efficiency static pressure box through the fan. After being filtered by the high-efficiency filter, 80-90% of the clean air is evenly sent into the working area of the weighing hood under the action of the uniform flow membrane, and 10-20% of the clean air is directly discharged outside the weighing hood. In this way, a negative pressure airflow is always formed in the working area of the weighing hood to ensure that dust does not pollute the room outward.
Product Features and Configuration Description:
Modular design, flexible and simple installation, with an integrated circular arc structure at the connection between the inner side and the ground;
The automatic frequency conversion system for wind speed detection ensures that the wind speed in the working area is always in a uniform and stable operating state (0.45 ± 20% m/s).
◆ Display the pressure difference before and after the filter (which can be directly displayed by a pressure difference gauge or a touch screen), monitor the effective operation of each filter in real time, and display an alarm for pressure difference exceeding the limit;
The unique airflow diversion design in the main workspace ensures negative pressure airflow in the weighing hood workspace, effectively protecting personnel safety and avoiding environmental pollution and product cross contamination;
Intelligent control mode and fault alarm system effectively ensure the reliability of operation;
Humanized design makes the replacement of various filters more convenient, and unique air duct design effectively produces the overall working noise of the machine;
Configure multiple industrial sockets with a protection level of IP66 for powering electronic weighing instruments inside the equipment.
◆ Can be equipped with a complete set of Siemens touch screens, PLC controllers, and frequency converters according to user requirements; It can also be easily configured by directly adjusting and controlling through the external panel of the frequency converter;
◆ Optional cooling coils or air conditioners can be installed to balance the heat generated during operation;
◆ Customize non-standard size weighing rooms according to user requirements.
