Product Description

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.

Principle of Transfer Window

The transfer window is a device installed at the entrance and exit of a clean room or between rooms with different cleanliness levels to block indoor and outdoor airflow. When transferring goods, it prevents contaminated air from entering cleaner areas and causing cross-contamination.

Air Shower Mechanism: When transferring materials, the top blows out high-speed, clean airflow to blow away dust particles on the surface of the goods. During this process, the doors on both sides act as an airlock, ensured by high-quality sealing strips for air tightness.

Advantages & Application

Constructed from flat and smooth stainless steel plates, our transfer windows feature unpowered rollers for easy item movement. The double doors are interlocked and equipped with ultraviolet germicidal lamps to ensure sterile transfers.

Operational Guidelines:

The door remains closed normally; users must use the doorbell to signal the other side.
Strictly prohibited to open both doors simultaneously.
Interlocking devices ensure only one side can be opened at a time.
Regular cleaning and disinfection are mandatory after operations.

Hygiene & Maintenance

Management should follow the cleanliness requirements of the highest-rated connected area. Operators are responsible for wiping internal surfaces and activating UV sterilization for 30 minutes after each shift.

Critical Precautions:

Do not force doors open; resistance indicates the opposite side is still open.
Ensure material surfaces are cleaned when moving from low to high cleanliness areas.
Regularly check and replace UV lamps to maintain sterilization efficiency.
The transfer window is for passage only; do not use it for storage of debris.

Frequently Asked Questions

What is the primary purpose of a transfer window?

It is used to transfer small items between clean and non-clean areas, minimizing the need to open clean room doors and reducing the risk of environmental contamination.

How does the interlocking system protect the clean room?

The electronic or mechanical interlocking system ensures that only one door can be opened at a time. This prevents direct airflow between two areas, maintaining the pressure and cleanliness of the room.

How often should the UV sterilization lamp be used?

It is recommended to activate the UV lamp for 30 minutes after each shift or after a transfer operation to ensure the internal surfaces remain sterile.

What should I do if a door will not open?

Do not force the door. This usually happens because the door on the opposite side is not fully closed. Check the other side to ensure the interlock is released.

Are these transfer windows easy to clean?

Yes, they are made of high-grade stainless steel with a smooth, flat surface specifically designed for easy disinfection and resistance to microbial growth.
