1. The fan has good aerodynamic performance, low running balance vibration, high efficiency, long service life, etc. 2. Indoor ventilation and dust removal in industrial and mining enterprises, large buildings, hotels and restaurants. 3. This series of fan is an efficient and energy-saving centrifugal fan. Its airfoil blade, curved impeller front disk, cone arc inlet collector and other structures enable the fan to have high efficiency, low noise, small size, and strong reliability. In special cases, the air volume can be controlled with a regulating valve. (It can produce explosion-proof B4-72 explosion-proof centrifugal fan and anti-corrosion F4-72 anti-corrosion centrifugal fan) Precautions for installation and use: Read the fan instructions before using the fan to help you use the equipment correctly. 1. Check the components and main parts of the fan before installation to check whether the parts are damaged, friction, etc. If there is any abnormality, it should be repaired before it can be officially used. 2. Check whether there are sundries and tools left inside the casing. 3. The air duct should have a separate support, and the fan should not bear the weight of the air duct. 4. When installing the C-type fan, make sure that the position of the fan wheel in the air casing is correct, and ensure that the end face of the pulley is flush. 5. When installing the D-type fan, make sure that the position of the impeller in the air casing is correct, and ensure that the motor and the shaft are coaxial. 6. When the bearing seat of the transmission group leaves the factory, the transportation problem should be considered. There is no lubricating oil inside. After the fan is installed, please add lubricating oil to the bearing seat. Add 20# lubricating oil to the fan running at room temperature, and add 30# when running at a higher temperature. Lubricating oil, the amount of refueling is appropriate if the oil level is located in the middle of the oil sight glass of the bearing seat.
