Rotary fan, also known as hongyun fan or box fan, box fan The shell and blades of this type of fan are injection molded from ABS engineering plastics and are fully enclosed. It has the advantages of lightweight, smooth operation, good insulation, safety, and reliability, etc. The blades of box fans are generally more than three blades, mostly five blades, which makes it possible to produce the same size of wind volume and wind speed, the rotational speed of the blades can be a little slower. Ordinary electric fans are different from this fan is equipped with a wind-guided page, so it is called a hinge fan. Most of the rotary pages are by a special micro synchronous motor bare move, 5 revolutions per minute. The wind blades transfer the wind sent by the wind-guided page, forming a net array of natural wind so that people feel comfortable.
Warm tips: fan work in the air is easy to adhere to the dust, cleaning need to cut off the power supply for cleaning. Industrial exhaust fan: mainly used for forced air convection. Electric fans are used for a long time, the fan blade is easy to get a lot of dust underneath. This is due to the electric fan at work, due to fan blade and air friction, fan blade with static electricity, charged objects can attract small light objects, which can adsorb tiny dust floating in the room.
