Negative Pressure Weighing Hood

Negative pressure weighing room is a purification equipment designed for weighing raw materials and auxiliary materials, sampling dry materials or products in the purification area, and is mainly used in pharmaceutical, microbiological research and scientific experiments.

The system is equipped with primary, medium and high-efficiency filters, which provide a vertical one-way airflow to the weighing work area, which can effectively control dust flying, most of the clean air circulates in the work area, and a small part of clean air is discharged to the background area , so that the working area generates negative pressure relative to the background area, prevents cross-contamination, and protects the clean environment and the safety of indoor personnel.
