- 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.
|
| |
 |
- 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.
