The activated carbon adsorption box removes organic pollutants and odor molecules from waste gas by virtue of the porous structure of activated carbon to realize gas purification. Adopting drawer-type structure, it enables convenient disassembly and replacement of activated carbon. It runs stably with low noise and requires no additional chemicals. Widely used for treatment of organic waste gas and malodorous gas in spraying, printing, chemical industry, feed processing and other fields, it is common environmental waste gas treatment equipment.
