The top of the clean gas storage cabinet is equipped with a fan and a filtering device. The operation of the fan creates a negative pressure in the cabinet, and the air enters from the air inlet. The air of toxic gas and dust will be filtered by the activated carbon filter and particle filter, and it will be clean after filtration. The air returns to the room. The clean gas storage cabinet is used to protect laboratory personnel from inhalation hazards when storing chemicals, and at the same time, it can continuously filter the indoor air for 24 hours.
The activated carbon filter of the clean gas storage cabinet filters volatile substances. The lower the wind speed and air volume passing through the filter, the better the filter effect. Fan speed regulation is applicable to: Low speed-the chemical storage capacity is too large and cannot be adsorbed in any way. At this time, as long as the cabinet is under negative pressure, the chemical will not seep out. At the same time, the filter has a strong adsorption capacity to achieve the filtering effect. The medium speed is what the respondent calls the appropriate wind speed. High speed, suitable for purifying laboratory air. At this time, there are very few volatile drugs in the cabinet and a small amount of volatile matter in the laboratory air. The opening of the wind speed is conducive to the rapid filtration of the air.
Filtered storage cabinets can be used in quality control laboratories (QC laboratories), medical laboratories, forensic laboratories, product development laboratories for storage of fixed powder chemicals of toxic chemicals, and used in entry-exit inspection and quarantine bureaus, Environmental testing stations, food and drug supervision and inspection institutes, disease prevention and control centers, product quality supervision and inspection institutes, pharmaceuticals, chemicals, food, tobacco, flavors and fragrances, water industry, petrochemicals, research institutes, universities, hospitals, steel and other places experiments room.
