Rail Fan / electric fan

The motor fan is mostly used in a type of stand and tower. The vertical motor fan has a demerit that it is inconvenient if you turn on it while the cookware is on in the house or restaurant as it influences the gas flame by the wind.
It is the motor fan using the rail. You can change the direction to where you want by moving the motor fan up and down or left and right repeatedly and using horizontally as well as vertically.
