China Suppliers Transfer Window for Clean Rooms - Air Purification Equipment from a Leading Factory
The transfer window is an auxiliary equipment for clean rooms. It is mainly used to transfer small items between clean areas and between clean areas and non-clean areas to reduce the number of times the clean room opens and reduce the pollution to the clean room.
Q: What is the main purpose of a clean room transfer window?
The primary purpose is to allow the transfer of small items between clean areas or between clean and non-clean areas without opening the main clean room doors, thereby minimizing air pressure loss and contamination.
Q: How does the interlocking system of a pass box work?
The interlocking system (either mechanical or electronic) ensures that both doors of the transfer window cannot be opened at the same time. When one door is opened, the opposite door automatically locks to prevent direct airflow between the two environments.
Q: What is the difference between a static and a dynamic transfer window?
A static transfer window is used for standard material transfers between two clean areas of similar cleanliness levels. A dynamic transfer window includes a built-in HEPA filtration and fan system to actively clean items and maintain a higher clean class environment during transfer.
Q: Can UV sterilizing lights be installed inside the transfer window?
Yes, ultraviolet (UV) germicidal lamps are commonly integrated into transfer windows to sanitize the surface of items and prevent microbial contamination before they enter the clean room.
Q: What materials are clean room pass boxes typically made of?
They are usually constructed from high-quality stainless steel (such as SUS 304 or SUS 316) because it is durable, corrosion-resistant, easy to clean, and does not shed particles.
