The Whole House Fan is installed inside the roof space.
A wind operated shutter trims the ceiling opening below.
When the fan is switched on, the ceiling shutter blades pivot open and the fan sucks air up very powerfully.
Air from rooms is forced to travel through the house towards the fan. You can feel the air movement on your skin.
The air rushes up through the ceiling shutter and swirls into the roof space at high speed.
Air in the roof space is pressurized by the huge amount of incoming air.
Roof space air is forced outside rapidly through extra vents installed under the eaves or on the roof.
Fresh outside air flows in though windows to replace air sucked out of rooms.
With greatly reduced heat build up in the house around you and a gentle breeze on your skin you can be comfortable for 100% of summer nights and most summer days.
