DESCRIPTION
Cascade Whole House Fans are mechanical ventilation cooling systems. The occupant-controlled system allows for low temperature
outdoor air to be introduced in a home or building through open windows. The indoor air is circulated to cool the living space
and exhausted into the attic where it is then vented to the outdoors. Outdoor air will warm relative to the indoor temperature
and the low energy ventilation cooling fan is disengaged and windows closed.
