The Ductless Fume Hoods is equipped with 1-4 original imported fans. The air in the laboratory enters from the opening of the inclined front door panel. Various toxic and harmful gases and dust generated during the experimental operation are adsorbed and filtered by the high-efficiency molecular filter to form pure gas, which is discharged out of the cabinet, so as to achieve the purpose of purifying the air in the cabinet and indoor air, and effectively protect the inhalation hazards caused by laboratory personnel operating chemicals.
The features of the fume hood are as follows:
1. There is no need for complicated installation works (no need for external pipes, fans, air supplement systems, etc.). This cabinet is independent (built-in fan), and can work when plugged in;
2. Efficient energy saving (no need to consume any air conditioning cold and warm air);
3. Environmental protection (not discharged into the atmosphere, not polluting the environment);
4. Adopt turbine type silent fan (45dba);
5. Movable trolley with roller;
6. The biggest feature is the adsorption of toxic and volatile chemicals by molecular filters. It can completely protect laboratory personnel;
Is the working environment safe for researchers?
The study found that the air pollution of rooms containing chemicals was 100~400 times higher than that of ordinary rooms. There
are 111000 deaths caused by indoor air pollution in China every year. The death rate of laboratory workers was 42.7% higher than that of the general population. The average life span of laboratory staff is also 10 years less than that of ordinary people. Air pollution in laboratories has long been the chief culprit for the physical and mental health of scientific researchers.} What do researchers neglect when they concentrate on scientific research?} Research shows that there are more than 40 kinds of occupational diseases caused by chemical factors, and organic solvents, sulfur oxides, chlorine and other chemical elements are the inducements of the diseases. meanwhile, β- Naphthylamine, vinyl chloride, arsenic and their compounds are also the reasons for the high incidence of cancer in laboratory personnel. However, since the incubation period from initial exposure to carcinogens to cancer is as long as 20 years or more, the prevention of occupational diseases and occupational cancer has not attracted the high attention of experimenters.
Control the diffusion of chemicals into the air from the source
The gas purifying fume hood can control the diffusion of chemical gas from the source. The chemical smell produced in the laboratory is volatilized and diffused into the air with the production of chemical experiments. The Ductless Fume Hoods can collect the volatilized gas in the filter device at the first time. The clean gas medicine storage cabinet can enable the chemical reagents in the laboratory to be stored in an orderly and standardized manner, absorb the toxic and harmful chemical gases volatilized from the reagent bottles, and recycle the air inside the laboratory with an air handling capacity of 90 cubic meters per hour, so as to improve the air quality in the laboratory and protect the safety and health of personnel.
