The working principle of the laminar flow Pass Box
2024.08.07
The working principle of the laminar flow Pass Box is as follows:
The laminar flow Pass Box is a device used for transferring items in a clean environment.
Its working principle is based on laminar flow technology. A fan and a high-efficiency filter are installed inside the laminar flow Pass Box. The fan sucks in air, and after filtering through the high-efficiency filter, a uniform laminar airflow is formed.
When the item is placed on one side of the Pass Box, the side door is closed. On this side, the filtered laminar airflow blows on the surface of the item to remove particles and pollutants that may be attached.
Then the personnel on the other side can open the door to take out the item. During the entire transfer process, due to the presence of laminar airflow, it can effectively prevent unfiltered air from the outside from entering the Pass Box, maintaining the cleanliness of the inside of the Pass Box.
For example, in the electronic chip production workshop, the laminar flow Pass Box can ensure that the chip will not be contaminated by tiny particles in the air when it is transferred between different clean areas. In biological laboratories, laminar flow Pass Boxs can provide a reliable clean environment for the transfer of experimental samples to prevent samples from being contaminated by the outside or cross-contaminated.
