1. Negative pressure weighing room description

The negative pressure weighing room is the main quality equipment of HongKong Yaning Purification Industrial Co.,Limited. The company has long focused on consulting, R&D, design, production and service of the negative pressure weighing room. Widely used in microbiological research, scientific experiments, or pharmaceutical industries. The weighing chamber is a dedicated local purification equipment. Negative pressure weighing chambers provide clean air circulation in the work area, resulting in vertical unidirectional airflow. , The remaining non-clean air is discharged outside the working area, so that the working area is in a negative pressure working state, which can effectively avoid pollution and ensure that the working area is in a highly clean state.

Operating Features:

1: Negative pressure weighing room modular. Easy-to clean rigid design with minimal joints

2: HEPA/ULPA Gel-seal down flow filter are replaceable from within the booth.

Gel-seal is more reliable than conventional gasket seals

3: Voltage-compensating blowers ensure stable air flow.

4: Magnehelic Gauges provide convenient and reliable means for monitoring

gauges air flow and filter condition.

5: Containment performance verified according to the ISPE good practice guide,

assessing the particulate containment performance of pharmaceutical equipment.



2.Weighing room attention

When the negative pressure weighing room is used, it is necessary to select the indoor use type or the outdoor use type according to the use environment. If the negative pressure weighing room is used indoors, firstly select the floor that can withstand the weighing room and select the installation. The location confirmation must be flat. The weighing room cannot be tilted during installation. Once tilted, it will affect the shape of the box and cause malfunction. If the environment is relatively high or relatively low, there are oil mists, chemical corrosive substances are relatively large, etc. These environments cannot use weighing rooms. There must be no flammable or explosive materials in the working area of the weighing room. The weighing room cannot be used continuously for a long time in use, and it will cause harm to the symmetrical room when it is used for a long time. Do not use clean water when cleaning. If you wash with water, it will cause damage to equipment or personnel. To use professional cleaning fluids, symmetric chambers should be regularly maintained.
