Hello, how long the electric fan can run continuously with the small gear on depends on the actual product quality of the electric fan. Brand fans produced by relatively large regular factories can be used for more than one year as long as the motor casing is touched. Some electric fans in the computer room are on all the year round. As for the general low-grade electric fan, it doesn't matter if it is turned on for more than ten hours, but it may not be safe to turn it on for several days. Please refer to it.
