Negative Pressure Weighing Room - High Precision Equipment
The negative pressure weighing room is specialized local purification equipment designed for pharmaceutical production, microbial research, and scientific experiments. It provides a vertical unidirectional flow, where part of the clean air circulates within the working area and part is discharged to ensure a negative pressure environment. This design effectively prevents cross-contamination and ensures high cleanliness in the workspace.
During the weighing and packing of dust and reagents, the equipment controls spills and rising particles, protecting personnel from inhalation hazards while safeguarding the external environment and indoor air quality.
