Air shower transfer window

The transmission window is the most effective device to prevent pollution. Its characteristic is double door interlock, reduce the number that staff enters purify room effectively because of carrying article, prevent outside air to enter purify room. The complete set of equipment is economical and affordable, which is the best transfer device for the purification room. At the same time, the transfer window is also an air purification equipment used in the clean room, suitable for the transfer of medium and small goods between clean room and clean room or between clean room and non-clean room. By using the transfer window, the number of times the clean room is opened and closed can be reduced to minimize the pollution of the clean area. The products are widely used in fine technology, electronics industry, biological laboratory, pharmaceutical factory, hospital, food processing industry and other air purification sites.



Transfer window





The air shower transfer window is designed according to the type of the air shower, the fan quickly blows out the air into clean air after the high efficiency filter, the clean air is sprayed out by the stainless steel spray head and nozzle, the airflow velocity is up to 20M/S above, the dust particles attached to the surface of the object can be quickly and effectively cleared. After circulating air, it is purified by primary filter with double filtration and strong usability. Is a kind of clean room auxiliary equipment, mainly for the clean room and non clean areas or between different levels of different pressure between clean room equipment transfer small objects, on the one hand, have the effect of air brake, keep high-level clean room in the high pressure by pressure, on the other hand, in the process of transfer implementation blowing leaching effect, to ensure that goods entering a clean area clean, reduce the cross contamination on objects; The time can be adjusted according to the manual switch, the maximum to achieve the effect of spray and energy saving.



Transfer window structure





The operation of air shower transfer window is as follows:

1. Materials entering and leaving the clean area shall be strictly separated from the flow of people, and shall be entered and left by the special channel for materials in the production workshop.

2. When the materials enter, the raw and auxiliary materials shall be sent to the temporary storage room of the raw and auxiliary materials through the transfer window after the person in charge of the preparation team organizes the personnel to remove the package or clean the appearance; After removing the outer packing from the outer temporary storage room, the inner packing material is sent into the inner compartment through the transfer window. The general staff of the workshop and the person in charge of the preparation and internal packaging process handle the material handover.

3. When passing through the transmission window, the provisions of "one open and one close" of the inside and outside doors of the transmission window must be strictly implemented, and the two doors cannot be opened at the same time. After the material is put into the outer door, close the door first, then open the inner door to take out the material, close the door, and so on.

4. When materials are sent out of the clean area, they should be transported to the relevant material intermediate station first and removed out of the clean area according to the reverse procedure when the materials entered.

5. All semi-finished products shipped from the clean area shall be sent to the external temporary storage room through the transfer window and transferred to the outer packing room through the logistics channel.

6. Highly polluting materials and wastes shall be transported to the non-clean area from their special transfer Windows.

7. After the material entering and leaving, the site and transfer window of each compartment or intermediate station should be cleaned in a timely manner, and the internal and external access doors of the transfer window should be closed to do a good job of cleaning and disinfection.

We need to pay attention to the following specifications when operating the air shower transfer window:

1. Wipe the object to be delivered with 0.5% peracetic acid or 5% iodophor.

2. Open the side door outside the delivery window, quickly place the items to be delivered, use 0.5% peracetic acid spray to disinfect the delivery window, and close the side door outside the delivery window.

3. Turn on the UV lamp in the transfer window, and uv light the objects to be delivered for at least 15 minutes.

4. Notify the experimenter or staff in the barrier system, open the inside side door of the transfer window, and take out the items.

5. Close the inside side door of the transfer window. It is mainly used for the transfer of small items between clean and clean areas or between clean and non-clean areas, so as to reduce the number of clean room opening times and reduce the pollution of clean areas to Z low level.
