What is a laminar flow pass box? In what scenarios is a laminar flow pass box generally used?

A laminar flow pass box is an airflow isolation device used in clean rooms. It uses a fan and a high-efficiency filter to automatically purify the airflow in the work area, and circulates the purified clean airflow to the work area, thereby dynamically maintaining the cleanliness of the work area. The main function of the laminar flow pass box is to effectively prevent cross-contamination between the rooms on both sides of the work area. The device is equipped with an ultraviolet germicidal lamp, which can effectively eliminate microorganisms and bacteria that grow in the work area to ensure the cleanliness of the work area.
A laminar flow pass box, also known as a 100-level laminar flow transfer cabinet or laminar flow transfer box, is a clean pass box with high cleanliness. It can achieve a 100-level purification effect and is an innovative clean transfer window. Its working principle is: the air after preliminary filtration is pressed into the static pressure box by a low-noise centrifugal fan, and then further filtered by a high-efficiency filter, and finally passes through the work area with equal pressure and uniform wind speed, so that a high-cleanliness working environment can be formed.
Usually, a laminar flow pass box is used in biological clean areas for the delivery of goods, and is commonly seen in pharmaceutical factories, biopharmaceuticals, scientific research units, disease control centers, large hospitals, university research, biological clean, and various clean areas of application. Due to the different production processes of laminar flow transfer windows, many manufacturers provide relatively different characteristics for them. Laminar flow pass box generally has the following characteristics:
1. The laminar flow pass box body is made of high-quality 304 stainless steel, with an inner arc design for easy cleaning.
2. Built-in PAO detection port and differential pressure gauge to monitor filter cleanliness verification and usage status.
3. Equipped with a touchscreen interface, conveniently set self-cleaning and sterilization programs, and view sterilization records.
4. The controller is automatically operated to simplify the user process.
5. Compact internal structure, card slot sealing strip, enhance air tightness.
6. Equipped with a HEPA filter, the filtration efficiency reaches 99.999%, ensuring a clean effect.
