Clean bench is designed to meet the needs of modern industry, the optoelectronic industry, biopharmaceuticals and scientific research and testing for the cleanliness of local working areas. The air is sucked into the pre-filter through the fan and filtered through the static pressure box into the high efficiency filter, which sends the filtered air out in a vertical or horizontal airflow, so that the operating area can reach class 100 cleanliness and ensure the production requirements for environmental cleanliness. Principle In a specific space, the indoor air is pre-filtered by the pre-filter, pressed into the static pressure box by a small centrifugal fan, and then filtered by the high-efficiency air filter. The clean air blown from the air outlet of the high-efficiency air filter has Accurate and uniform cross-sectional wind speed can eliminate the original air in the work area and take away dust particles and biological particles to form a sterile and high-clean working environment. Use In factory production, the workload of inoculation is very large, and when it is necessary to work for a long time, the horizontal laminar flow clean bench is an ideal equipment. The advantages of the ultra-clean table are that it is convenient and comfortable to operate, relatively comfortable, high work efficiency, short preparation time, can be operated in more than 10 minutes after starting up, and can basically be used at any time. The service life of the ultra-clean table is related to the cleanliness of the air. In temperate regions, ultra-clean benches can be used in general laboratories. However, in tropical or subtropical areas, due to the high amount of pollen in the atmosphere, or areas with a lot of dust, the ultra-clean table should be used in a better indoor room with double doors. Application Clean bench is a one-way flow air purification equipment that provides a local dust-free and sterile working environment. It is suitable for scientific research and production departments that require a local clean and sterile working environment, such as medicine and health, biopharmaceuticals, food, medical science experiments, optics, electronics, aseptic room experiments, aseptic microbial inspection, plant tissue culture and inoculation.
