Negative Pressure Weighing Booth

Negative Pressure Weighing Booth is a type of partial purification equipment specifically designed for pharmaceutical, microbiological research, and scientific experiment areas. It provides a vertical unidirectional airflow, where part of the clean air circulates in the work area and the rest is discharged to the nearby area. This setup enables the work area to generate negative pressure, preventing cross-contamination and ensuring a high level of cleanliness in the environment.

The booth is ideal for weighing and packaging dust and reagents. It effectively controls the overflow and rise of dust, minimizing the inhalation hazards posed to humans while avoiding cross-contamination. Additionally, it protects the safety of both external environments and indoor personnel, ensuring compliance with high safety and cleanliness standards.
