SJG  Diagonal flow duct fan Purpose 

    Diagonal flow fans are widely used in pipeline pressurization, air supply and exhaust, and ventilation places of high-rise buildings and public buildings. 


Features 

    The flow is larger than the centrifugal fan, the total pressure is higher than the axial fan, and the volume is smaller than the centrifugal fan. 


Fan maintenance and use 

    It can only operate when the fan equipment is completely normal. 

    If the fan equipment is started after maintenance, please pay attention to whether all parts of the fan are normal.  

    Regularly remove dust, dirt and impurities inside the fan and conveying pipeline, and prevent rust. 

    Repair of fan equipment is not allowed to be carried out during operation. 

    If it is found that the flow is too large and does not meet the requirements for use, or a small flow is required in a short time, the throttling device can be used to adjust. 

    During the driving, stopping or running of the fan, if any abnormality is found, the operation should be stopped immediately and inspected.
