Mobile clean air type suction hood ventilation cabinet full window

1Background Analysis

Laboratories are places for scientific research and experimental operations, widely used in fields such as education, research, production, and quality inspection. However, the health issues of personnel engaged in experimental work are currently worrying. Epidemiological studies in the United States, Sweden, and the United Kingdom have shown that the mortality rate of chemical workers, especially laboratory workers, is much higher than that of the general population; According to statistics released by the US Occupational Safety and Health Administration, the lifespan of laboratory personnel is 10 years shorter than the average lifespan of normal individuals.

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

Based on the analysis of policies and regulations released in recent years, relevant environmental regulations will gradually be updated and improved in the future. The latest laboratory volatile organic pollution prevention and control technical specification DB11/T1736-2020, released in 2020, has made relevant requirements. Among them, laboratory units should establish a registration and management system for the use of organic solvents, formulate experimental operation specifications, select effective exhaust 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 should be ensured to be carried out simultaneously with the experimental operation.

IIProduct features

SeyfertClean air type fume hoodThe series is based on the product concept of compliance, environmental protection, health, and safety. It is equipped with activated carbon molecular filters and air particle filters, which can adsorb most chemical gases. When researchers conduct chemical experiments in the cabinet, harmful gases are adsorbed by the filters in the filtering device, and the filtered air circulates indoors,Clean air type fume hoodNot discharging exhaust air outdoors, thus reducing the energy consumption (cost) of air conditioning and ventilation systems; Moreover, due to the adsorption of harmful gases by the filter, they are not directly discharged outdoors, which can reduce pollution to the atmospheric environment. The control concentration of the exhaust cabinet, the face wind speed of the operating port, and the exhaust purification effect of the chemical storage cabinet meet the standards of NFX 15 211:2009 (certified by ANSI Z 9.5-201), ASHRAE 110:1995, and JG/T38-2012 "Ductless Self Purifying Exhaust Cabinet".

The product has 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. Its application industries involve education and research, inspection and quarantine, medical and health, food and pharmaceuticals, chemical engineering, environmental safety and many other fields.

5、 Product working principle

1. Air inlet

Air can be directly drawn from the laboratory into the fume hood, creating negative pressure. The stable surface air velocity forms a natural barrier to isolate users from the chemicals they are handling.

2. Comprehensive filtration system

The fan system inhales toxic and harmful gases upwards, filters them, and returns clean air indoors. The excellent control concentration of the cabinet can ensure that the chemical gases inside the cabinet will not return indoors, causing pollution.

3. Clean laboratory air

Configure different filters according to different operations to effectively filter toxic and harmful gases, purify laboratory air, remove chemical residues and odors, and improve laboratory cleanliness levels.

4. Purifying the surrounding air

The continuous filtration efficiency of the fume hood can help purify indoor air
