AI Technical Summary

Technical Problem

Existing positive pressure transfer windows have insufficient sealing, which may lead to the risk of internal contaminants leaking into external rooms, especially when transferring harmful, toxic or highly reactive substances.

Method used

A negative pressure transfer window is designed. By setting up components such as a return air mesh plate, an air supply device, a filter device, and a regulating valve, the airflow is ensured to form negative pressure in the transfer chamber to prevent internal objects from contaminating the external room. Pre-filters and high-efficiency filters, as well as a sterilization device, are used to improve the purification effect.

Benefits of technology

It achieves self-cleaning within the transfer chamber, maintains a negative pressure state, avoids contamination of the external environment by items, and improves the safety factor, especially when transferring volatile items.
