Newly Developed Automatic Ventilating Fan

Specifications and Product Details:

1. Problems of traditional shutter fans

- Shutters break often.
- Shutters reduce ventilation.
- Shutters get rusty.
- When the electric power is off, conventional shutters stay open, letting dust and insects enter

freely.
- When running, regular shutter fans spread dust into the air and accumulate dust particles

behind the shutters.
- On ordinary fans, closing the shutter after running just creates more dust.

2. Features of automatic ventilating fan

- No need for additional shutters.
- Shutter maintains good ventilation.
- Even if electric power is off, the blades close automatically with no need for manual control.
- Simple to operate: When turned on, the shutter opens to become the blades of the fan. When

off, they automatically form a closed shutter. - It is easy to connect the unit to thermostats,

gas detectors, etc.
- The blades close completely, forming a shield against insects and unwelcome odors.
