The Gerun tubeless clean gas reagent cabinet and tubeless clean gas type fume hood are mainly composed of cabinets, fans, and high-efficiency filtration systems, designed specifically for adsorbing gases evaporated from chemical drugs*The fan filters the toxic gas in the cabinet into clean gas through a high-efficiency filter and discharges it.
