Advantages of Self-cleaning Pass Box
Excellent cross contamination control
The filter achieves a filtration efficiency of up to 99.995% for particles as small as 0.3μm. The interior of the enclosure is constructed from 304/316 stainless steel in a single-piece molding process, creating seamless, no-blind corners and preventing contaminants from lurking, making it extremely easy to clean and disinfect.
Intelligent Control And User-Friendly Operation
Equipped with a touchscreen PLC controller, the unit displays real-time parameters such as air speed, differential pressure, and UV lamp operating status. A dual interlock function and internal self-cleaning cycle mode provide intelligent and convenient operation.

Ultimate reliability and long service life
The self cleaning transfer window is made of 1.2mm thick high-quality cold-rolled steel plate, and the surface is treated with anti-corrosion electrostatic spraying to ensure that it will not rust for a long time in a humid clean room environment.
Energy-saving and high-efficiency, reducing operating costs
The fan utilizes variable speed control technology, monitoring changes in filter resistance in real time and automatically adjusting speed to maintain rated airflow. This design significantly improves energy efficiency and reduces operating costs.
