China Air Purification Transfer Window Suppliers for Cleanroom Equipment in Factories and Laboratories
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.
Pollution Reduction
Effectively prevents external contaminants from entering the controlled cleanroom environment during material transfers.
Minimized Openings
Reduces the frequency of personnel entering and exiting, maintaining stable pressure and cleanliness levels.
Auxiliary Optimization
Serves as an essential auxiliary passage to streamline workflows between clean and non-clean zones.
❓ Frequently Asked Questions
What is a clean room transfer window?
A clean room transfer window (also known as a pass box) is an auxiliary device designed to transfer small objects between clean areas of different cleanliness classes, or between clean and non-clean zones, ensuring minimal disruption to the cleanroom environment.
How does a transfer window reduce cleanroom contamination?
By allowing small items to be passed through a sealed chamber rather than opening full-sized doors, it prevents large volumes of outside air and airborne particulates from entering the cleanroom.
What is the difference between static and dynamic transfer windows?
Static transfer windows are used for standard transfers between two clean areas of similar cleanliness. Dynamic transfer windows feature built-in HEPA filtration and fans to actively clean items as they are passed through, suitable for transfers between clean and non-clean zones.
Can both doors of a transfer window be opened simultaneously?
No. Transfer windows are equipped with mechanical or electronic interlocking systems that prevent both doors from being opened at the same time, maintaining the pressure barrier.
What materials are transfer windows made of?
They are typically constructed from high-quality stainless steel (such as SUS304) on the interior and exterior to ensure durability, corrosion resistance, and ease of sanitization.
