Definition of DOP laminar flow pass box
Definition of DOP laminar flow pass boxDOP laminar flow pass box is a vital auxiliary equipment in a clean room. It is mainly used for the transfer of small items between clean areas and non-clean areas, or between clean areas of different cleanliness levels.Its core function is to reduce the number of times the door of the clean room is opened, thereby minimizing the pollution to the clean area. During operation, to reduce the dust particles brought in and out of the goods, the air shower transfer window will be filtered by a high-efficiency filter, and the clean airflow generated will be sprayed on the goods in all directions by a rotatable nozzle, quickly and effectively removing the dust particles. Then these dust particles will be filtered by the primary and high-efficiency filters and recirculated to the air shower area. The positioning of the DOP laminar flow transfer window in the clean room is obvious. It adopts a series of carefully designed features to ensure its efficient operation and good sealing. For example, the use of arc corners that are more suitable for the principle of clean rooms is not only beautiful, but also can reduce airflow resistance and dust accumulation; the outer wall is made of high-quality 304 stainless steel, which is durable and easy to clean; the short-distance transfer window work surface is made of stainless steel plate, which is flat, smooth and wear-resistant, and the long-distance transfer window work surface uses a non-powered roller to facilitate the transfer of items. In addition, the double-layer hollow glass tempered door is equipped with a mechanical interlock or electronic interlock device to ensure that the doors on both sides will not be opened at the same time to avoid cross-contamination. The wind speed of the nozzle outlet is as high as 20s or more, and the efficient air filtration efficiency can reach 99.99%, ensuring the purification level. At the same time, EVA sealing material has excellent sealing performance, coupled with imported electronic components, and reliable performance. In general, the DOP laminar flow pass box plays a key bridge role in the clean room. While ensuring the transfer of items, it strictly controls the spread of pollution and maintains the environmental quality of the clean room. |
