all-steel fume hood system is one of the most important systems in the laboratory. Most laboratories require general exhaust or local ventilation when in use. Since a large amount of harmful gases may be produced during the experiment, in order to protect the hygiene of the laboratory and its surrounding environment and prevent laboratory personnel from inhaling or swallowing harmful gases, it is recommended to choose a laboratory fume hood to achieve ventilation and exhaust to make the laboratory air fresher. So how to effectively use all-steel fume hoods to purify indoor air?

        This product is mainly used for chemical experiments with odor and harmful gas emissions. Usually, similar experiments are done on its console. During the experiment, a specific suction wind speed is generated at its exhaust port, which can discharge harmful gases generated during the experiment out of the laboratory in a timely manner. Stable surface wind speed can prevent harmful substances in products from spilling into the laboratory, protect the health of laboratory personnel to a large extent, avoid damaging the use of laboratory instruments and equipment, and improve the efficiency and accuracy of the laboratory. The wind speed on the product surface is generally not less than 0.5m/s. When operating some equipment that easily produces harmful gases, flammable and explosive or dust particles, the wind speed on the product surface should not be less than 0.7m/s. When experiments are not being carried out, ventilation in the laboratory should also be ensured, generally not less than 0.3m/s.

        ventilation system can use one fan connected to oneAll steel fume hoodOr one fan corresponds to multiple fume hoods. The airflow produced by the fan and ventilation system do not interfere with each other. This system is only suitable for laboratories or small laboratories with a small number of all-steel fume hoods. This system will increase the investment cost of the enterprise and reduce the overall efficiency of the wind turbine. One fan corresponds to multiple products and is suitable for large or multi-story laboratories. Depending on the nature of the chemical, multiple products share a fan and exhaust pipe.

        For some large experimental equipment or experimental operations that cannot be carried out in the cabinet, an exhaust cabinet with a simple structure and easy manufacturing can be used on the upper part or side. The cross-section and shape of the cover can flexibly match the diffusion shape of hazardous substances and be as close as possible to the emission point of hazardous substances without affecting process operations.

        Under normal circumstances, when experiments are not being carried out, laboratory personnel will habitually turn off the ventilation system, causing pollutants in other indoor space areas to gradually spread or the fume hood is not closed tightly, resulting in the leakage of harmful substances remaining in the cabinet, polluting the indoor air. These require the room to have an integral exhaust system, which can be used in conjunction with local exhaust systems.
