The fan inside is energized by natural wind to achieve a cooling effect. Types can be categorized by motor structure: single-phase capacitor type, single-phase shaded-pole type, three-phase induction type, DC and AC/DC dual-use series-excited commutator type electric fans.
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.
