When retarder axial fans for ventilation axial fans swf, due to the small amount of wind axial fans, in addition to food is a poor conductor of heat axial fan 380v, the individual parts of the initial ventilation prone ventilation slow 5 # axial fans, along with ventilated warehouse proceed full grain temperature will gradually balance carried retarder ventilation must be vibration sieve grain cleaning and impurity regions into axial fans must be promptly cleaned grain warehouse automatic classification within which they otherwise could easily lead to local ventilation is not are. Advantages centrifugal fan: cooling, precipitation effect is obvious, ventilation time is short; Disadvantages: high energy consumption; ventilation timing was bad prone to condensation. Conclusion: In order to cool down for the purpose of ventilation, the application of axial fans safe, efficient, energy-efficient ventilation retarder; centrifugal fan application in order for the purpose of ventilation in precipitation.
