Description

Technical Field

[0002] Laminar flow transfer windows are mainly used in biological clean areas for the transfer of items. The main application places are: biopharmaceuticals, scientific research units, disease control centers, large hospitals, university research, biological clean and various clean areas for application. Laminar flow transfer windows are an auxiliary equipment for clean rooms. They are mainly used for the transfer of small items between clean areas and between clean areas and non-clean areas to reduce the number of times the clean room door is opened and minimize the pollution of the clean room. The two doors of the laminar flow transfer window are interlocked with each other. When one door is opened, the other door cannot be opened. The other door must be closed before the other door can be opened to ensure that the doors on both sides cannot be opened at the same time, effectively preventing cross contamination; and the laminar flow transfer window is equipped with a fan and a filter. By blowing clean air to the items placed in the laminar flow transfer window, a large number of dust particles on the items are removed to ensure the cleanliness of the items when they enter the clean area.

[0003] When objects pass through the laminar flow transfer window, static electricity may be generated due to the contact and friction between the objects and the window, as well as the relative movement with the airflow. Static electricity not only attracts dust and microorganisms, reducing the cleanliness of the clean room, but may also cause sparks and discharges in flammable and explosive environments, thus causing explosions or fire accidents.
