    What is the difference between the 220V Cooling Fan and fan applications?

    Date: 2015-7-30   Click: 1546 Times

           A, "220V Cooling Fan" blower installation of different difficulty
           DC Blower often install air conditioning units in the inlet and outlet of the boiler drums, Fan and so on location, the installation is more complex, axial fans are often installed in the duct which, or the front end of the duct outlet.
           Second, different "220V Cooling Fan" blower air volume and pressure of
           1, DC blowers with high pressure coefficient, flow coefficient is relatively low, according to high and low pressure into high pressure (15000 ~ 3000Pa), MV (3000 ~ 1000Pa), low pressure (<1000Pa).
           2, axial fan with a low pressure high flow characteristics, according to high and low pressure into high pressure (500 ~ 5000Pa), low pressure (<500Pa). Mainly used for general place of low pressure ventilation with.
           Third, the different "220V Cooling Fan" blower on principle
           1. The principle of the axial fan: Axial enter the pressurized gas is discharged from the other side and then axial rotation leaves road.
           2. DC Blower principle: axial airflow into the whirling leaves road, at the outer edge of the impeller centrifugal force was thrown from the discharge outlet.
