Friedrich SM18 Fan Blade
The motor spins the blade which creates the stream of air from the unit. Along with blowing air out, it also takes air in which assists in keeping the wall unit cooled down whilst working.
What happens when my circulating fan blade is dying?
- The wall unit has difficulties trying to blow the proper amount of air as it tries to make the room more comfortable
- The main fan blade is cracked or wrecked in some way
- Blade in the unit causes a whine noise while blowing air
