Structure Description
Series cooling fans are composed of air hood, fan motor, fan blades, support frame, etc. The standard air hood is made of steel plate stretched and formed by a hydraulic press, and the extended air hood is The cover is welded and formed by steel plate coiling. The air inlet is composed of the smallest holes. The fan motor adopts a special design method that sacrifices the level of protection. This series of fans has the characteristics of simple installation, low noise, small vibration, and reliable operation.
Voltage and frequency used by series fans
Rated frequency can be,
Rated voltage single-phase,, etc.
Three phases,,,,,, etc.
Use environmental conditions

Maintenance
The fan should be connected to an independent power supply, and variable frequency power supply cannot be used. After the fan is powered on, check whether the direction of rotation is consistent with the direction marked. The fan is packed in cartons and should be handled with care during transportation to avoid collisions and knocks. It should be transported strictly together with corrosive substances such as acids and alkalis. The fan should be stored in a clean and well-ventilated warehouse with ambient temperature ℃ + ℃, relative temperature, and the air should not contain corrosive gases.
