Usage: It can be used directly or placed in a purification cabinet or adsorption bed. If the exhaust gas concentration is high and the emission volume is large, two purification cabinets or adsorption beds can be used alternately. During use, avoid excessively high temperatures, as high temperatures will reduce the adsorption capacity, which decreases as the temperature rises. At the same time, avoid high dust content and oil mist, as tar dust and mist can clog the micropores of activated carbon, increase resistance, and reduce adsorption efficiency. If the usage environment contains a large amount of dense dust and tar, a pre-stage dust removal filter should be installed to achieve better performance and a longer service life.
