     Piensi ductless clean air fume hood As a supplement to the traditional external exhaust fume hood, the ductless clean air fume hood has an irreplaceable role, so what is a ductless clean air fume hood, and the ductless clean air fume hood is also What are the advantages, please listen to the editor in detail: 1.
    As the name suggests, a ductless clean air fume hood is a fume hood that does not need to be connected to a duct, so how can the exhaust gas be discharged without a duct connection? First of all, the cabinet itself has its own fan and filter.
    The Beans ductless clean air fume hood comes standard with two layers of filters (two layers of molecular filters or a combination of one layer of molecules + one layer of high-efficiency filters).
    In the middle of the filter is a brushless fan, which can work continuously for 60,000 hours
    .

    2.
    The problem comes again.
    Since the exhaust gas is directly discharged into the room, how can we ensure that the exhausted air is clean.
    If the exhaust gas is discharged directly into the room, if the exhaust gas exceeds the standard and is directly discharged into the room, is the staff in a dangerous situation? Yes, every experimenter has such doubts.
    Biensi's ductless air purification fume hood adopts dual VOC probes for real-time monitoring.
    The exhaust gas has a certain purification ability after passing through the double-layer filter, so the purified air It must be tested and qualified to be discharged directly.
    The data is visually displayed on the 7-inch large screen, but the data of the exhaust gas can be viewed in real time.
    If the exhaust gas exceeds the standard (whether the temperature and humidity exceed the standard or the filter is saturated), it will alarm, and the alarm situation can be checked in time.

    .

    3.
    Since there is monitoring, can any kind of chemicals be operated in the ductless clean air fume hood? The answer is no.
    This type of fume hood is only suitable for the operation of small and medium doses of chemicals, because the adsorption of the filter takes time.
    If the instantaneous concentration is too high, it is likely that the filter has leaked before it is adsorbed.
    Causes an instantaneous high concentration alarm, so large-dose operation is not recommended for operation in the cabinet
    .

    Therefore, before purchasing this product, users must carefully communicate with the manufacturer's technicians to determine whether their operations match the use of ductless clean air fume hoods
    .

    4.
    The ductless clean air fume hood cannot completely replace the traditional fume hood.
    Although it has many advantages, such as low noise, convenient movement, simple installation, clean and safe appearance, it can only be used as a supplement to the external exhaust fume hood.
    It is more energy efficient, safer and cleaner to use
    .

    Wishing all our experimental staff a clean laboratory environment!
