[0031] Embodiment 1:

[0032] like Figure 1-3, a two-layer transfer window for transferring articles between different clean areas of a clean room, comprising: air shower transfer units arranged in parallel up and down; the air shower transfer units arranged in parallel up and down can work simultaneously; the air shower transfer unit comprises: a frame 1, the lower part of the frame 1 is a transfer cabin, and the upper part of the frame 1 is an installation cabin; a blowing unit, the blowing unit is arranged in the installation cabin, and is used to blow air with a preset wind speed to the transfer cabin; the wind speed of the air blown by the blowing unit to the transfer area is 18-20m / s. A return air unit, the return air unit is arranged in the transfer cabin, and is used to guide the air in the transfer cabin to the installation cabin.

[0033] In some embodiments, a partition is installed in the middle of the frame 1, and the partition divides the interior of the frame 1 into two independent transfer cabins and installation cabins. The front and rear sides of the installation cabin are respectively installed with a front object door 3 and a back object door 2. The front object door 3 and the back object door 2 are both made of stainless steel, and two transparent tempered glasses are installed on them to facilitate observation of the status of the items in the transfer area. The door opening and closing is controlled by an electromagnetic lock 8. The system sets the two object doors to interlock to prevent air exchange on both sides of the transfer cabin.

[0034] The blowing unit is a bottom-mounted FFU5 (including a fan and a high-efficiency filter), and the bottom-mounted FFU5 blows air with a preset wind speed to the transfer cabin to circulate the air and achieve a self-cleaning effect through high-efficiency filtration.

[0035] In some embodiments, the return air unit includes: a return air orifice plate 4, the return air orifice plate 4 is arranged on both sides of the transfer cabin, and the return air orifice plate 4 and the two side walls of the transfer cabin form a closed return air cavity, the top of the return air cavity is connected to the installation cabin, and a plurality of return air holes are arranged on the return air orifice plate 4.
