Filtered Storage Cabinet (all steel /PP)

Background analysis

Laboratory is a place for scientific research and experimental operation, which is widely used in the fields of education, research, production and quality inspection, but the health problems of people engaged in experimental work are worrying. The results of epidemiological studies in the United States, Sweden and the United Kingdom show that the mortality rate of chemical workers, especially laboratory workers, is much higher than that of the general population. Statistics released by the US Occupational Safety and Health Administration show that the life expectancy of laboratory workers is 10 years less than the average life expectancy of normal people.

The air pollution in the laboratory is an important factor that endangers the physical and mental health of researchers. If the application of ventilation is not proper, it may aggravate the indoor air pollution and cause the external air pollution in the area. As the most critical local exhaust equipment for laboratory air pollution control, the performance of exhaust cabinet directly affects the health and safety of laboratory personnel.

Based on the analysis of the policies and regulations issued in recent years, the relevant environmental regulations and documents will be gradually updated and improved in the future, and relevant requirements will be made from the latest Technical Specification for the Prevention and Control of Volatile Organic Pollution in Laboratories DB11/T1736-2020, which shall establish the registration and management system for the use of organic solvents in laboratories. Prepare experimental operation specifications, select effective waste gas collection and purification devices, reduce VOCS volatile organic compound emissions, and prevent pollution of the surrounding environment; The exhaust gas collection and purification device shall be ensured to be carried out simultaneously with the experimental operation.

Product function

Pure gas drug cabinet series with compliance, environmental protection, health and safety as the product concept, equipped with activated carbon molecular filter and air particle filter, can absorb most of the chemical gases, researchers in the storage of chemical substances in the cabinet, harmful gases are absorbed by the filter in the filter device, the filtered air is circulated in the room. The clean gas storage cabinet does not exhaust air to the outside, so the operation energy consumption (cost) of the air conditioning and ventilation system is reduced. Moreover, since the harmful gases are adsorbed by the filter and not discharged directly to the outside, the pollution to the atmospheric environment can be reduced, and the control concentration of the exhaust cabinet, the surface wind speed of the operating port and the exhaust air purification effect of the storage cabinet of chemical substances meet the requirements of NFX 15 211: 2009 standard (certified by ANSI Z 9.5-201), ASHRAE 110:1995 standard and JG/T38-2012 "ductless self-cleaning type exhaust cabinet" standard. 24 hours clean laboratory air, high efficiency and environmental protection.

The products have passed ISO9001 quality management system certification, ISO14001 environmental management system certification, OHSAS18001 occupational health and safety management system certification, EU CE and other related certifications. The application industry involves education and research, inspection and quarantine, medical health, food and pharmaceutical, chemical industry, environmental safety, national defense and many other fields.

Product working principle

1. Fan

The fan at the top of the cabinet pumps the air in the laboratory into the cabinet to generate negative pressure.

2. Gas filtration

The harmful gases volatilized by the reagents stored in the cabinet enter the filter module through the fan, the toxic and harmful gas molecules are trapped and filtered by the filter, and the clean gas returns to the room.

3. High quality air purification function

The filtered clean air returns to the room without endangering the health of personnel.

4. Purify the laboratory air

24 hours to purify the laboratory air, improve the laboratory air quality (drug cabinet should be kept on 24 hours).
