How it works: Flood Protection:The Smart VENTŪ door is latched closed until flood
water enters. Entering flood water lifts the patented internal floats which
unlatches and rotates the door open. This allows the flood water to automatically
enter and exit through the frame opening, relieving the pressure from your
foundation walls.
Ventilation: A bimetal coil (like a thermostat, no electricity is
needed) automatically opens and closes the ventilation louvers as temperature
changes. They will be closed when it is freezing outside and open when
it is warm outside to provide natural ventilation.
Important note:SmartVENTŪ does not rely on the louvers to let flood
water in and out. Regardless of the louvers' position, opened or closed,
when flood water flows into the door, the internal floats release the door
to rotate open to relieve the hydrostatic pressure. The louvers and pest
screen are rotated out of the path of the flood water. The temperature
controlled louvers are for ventilation purposes only.
