Negative Pressure Pharmaceutical Weighing Booth With Primary And Middle Efficiency Air Filter

Negative pressure weighing booth for pharmaceuticals industry

1. Negative pressure weighing booth description

The weighing chamber (hood) is a dedicated local purification device for pharmaceutical, microbiological, and scientific experiments, which provides a vertical unidirectional airflow. Part of the clean air is circulated in the work area and partially discharged to the nearby area, causing negative pressure in the work area. Dust and reagents are weighed and dispensed in the equipment to control dust and reagent spillage and increase, prevent dust and reagents from inhaling harm to the human body, prevent cross contamination of dust and reagents, and protect the external environment and the safety of indoor personnel.

2. Negative pressure weighing room principle

The weighing booth adopts the form of vertical unidirectional air flow, and the return air is first pre-filtered through the preliminary filter to remove large particles of dust in the air stream. After the pre-treated air, secondary filtration is performed through a medium-efficiency filter to fully protect the high-efficiency filter. Under the pressure provided by the centrifugal fan, through a high-efficiency filter, make it meet the cleanliness requirements. The operating area and the external environment form a relatively negative pressure, so as to ensure that the dust in this area will not spread to the outside and play a role in protecting the external environment.

3.Weighing booth structure

1). The weighing chamber is made of SUS 304 stainless steel plate;

2). Top configuration tank HEPA air filter;

3). At the bottom of the weighing chamber, configure the primary and middle efficiency air filter;

4). Weigh the top of the chamber and configure a uniform flow membrane to make the wind blow evenly.

5). Internal configuration high power low noise centrifugal fan;

6). The weighing chamber is equipped with two differential pressure gauges for monitoring the pressure difference of the intermediate efficiency air filter/the pressure difference of the high efficiency air filter;

7). The weighing room is equipped with a lifting table;

8). The overall structure of the weighing chamber is split type, which can be assembled on site;
