Dispensing Booth

Negative pressure weighing hoods are purification devices designed for weighing raw materials and excipients, drying materials, or sampling products in clean areas. They are mainly used in pharmaceutical, microbiology research, and scientific experiments. The system is equipped with primary, medium, and high-efficiency filters, providing a vertical unidirectional airflow to the weighing work area. This effectively controls dust dispersion, with most of the clean air circulating within the work area and a small portion being discharged to the background area. This creates negative pressure in the work area relative to the background area, preventing cross-contamination and protecting the clean environment and the safety of personnel within the area.
