The size of the electric fan is expressed by the diameter of the blade. The blade diameter refers to the diameter of the maximum rotation track of the blade, which is measured in "mm" or in inches (in). The blade diameters of general table fans and floor fans are divided into 200,250,300,350,400,600 (floor fans) and so on.
The unified arrangement of electric fan models is as follows: the first letter is the group code, for example, F represents the electric fan, the second letter is the series code, the third letter is the form code, and the following numbers are the production serial number and specification code. For example: Model FHS 3-35, represents 350mm covered pole motor series floor fan.
Box fan is also called Hongyun fan. The shell and blade of this kind of fan are made of ABS engineering plastic injection molding and fully enclosed. It has the advantages of light weight, smooth operation, good insulation performance, safety and reliability. The blade of the rotary fan is generally more than three blades, and most of them are five blades, which makes the wind volume and wind speed of the same size, and the speed of the blade can be slower. Different from ordinary fans, this type of fan is equipped with a wind guide, so it is called a fan. The page is mostly moved by a dedicated miniature synchronous motor, which rotates at 5 revolutions per minute. The wind delivered by the wind blade turns through the guide wind turning page, forming a network of natural wind, which makes people feel comfortable. Rotary fan has the advantages of light weight, smooth operation, good insulation performance, safety and reliability.
