PRODUCT
Equipment Type and Purpose:
The negative pressure dispensing booth is a high-performance device used in pharmaceutical, micro-electronics, and scientific research laboratories. It provides vertical unidirectional airflow. A portion of the clean air recirculates within the work zone, while another portion is exhausted to the surrounding area, creating a negative pressure in the work zone to prevent cross-contamination. It is used to ensure the cleanliness of the work zone and for material handling.
Automatic Wind Speed Variable System maintains uniform and stable airflow velocity in the work zone.
Filter and Flow Monitoring Device for real-time monitoring of the effective operation of each filter stage.
Low Noise Design effectively controls the overall operating noise of the unit.
Safety Protection Function Design: Includes failure rate assessment, test alarms, separation, controllable inspection, reagent detection, exhaust, protective measures, protection against hazards to personnel, transport safety, prevention of reagent cross-contamination, and protection of the external environment and personnel safety. Provides overall protection compliant with Class 100 ISO standards (NF, EN, ISO 14644-1) during operation.
