Negative pressure fan is a cooling principle using air convection and negative pressure ventilation. It is a kind of opposite from the installation site-the door or window naturally inhales fresh air, and the sweltering indoor air is quickly forced out of the room. Any problem of poor ventilation can be Improved machine, cooling and ventilation effect can reach 90% -97%. The function of this fan is very powerful. Ningbo air cooler, Ningbo air cooler

    1. Agriculture: Negative pressure fans were used for greenhouse planting earlier. Negative pressure fans are used for orchids or anti-seasonal plants.

    2. Animal Husbandry: Extending from greenhouse seeds is the use of animal husbandry. It is well known that the environment of chickens, ducks, and pigs directly affects the yield and survival rate. In other words, the quality of the environment is related to the profit of livestock.

    3. Industry: garment factories, shoe materials factories, toy hardware factories, etc. Negative pressure fans can be found everywhere in various industrial fields.

    4. Public places: It is common to install negative pressure fans in Internet cafes and canteens, which have low cost and high efficiency, and can also improve the harsh environment of dense population. There are also some shopping malls, auditoriums, stadiums, stations, hospitals, etc. use.

    The use of negative pressure fan is very good, with high efficiency. The shutters can be opened and closed automatically to be dustproof, waterproof and beautiful. It can be used for air blowing and air extraction, which is a good choice for cooling and ventilation in modern workshops. Environmental protection and energy-saving negative pressure fans will become the mainstream of ventilation and cooling equipment market.
