    The Smart Vent 1540-510 Stainless Steel Foundation Flood Vent is a dual function vent that works as a natural air ventilation system under normal conditions and a flood vent that relieves water pressure on your foundation and structure during flood conditions. These vents are used for a home or other type of structure with a crawlspace.


    A bimetal coil automatically opens and closes the ventilation louvers as temperature changes. No electricity is required. The louvers will be fully closed at 35F and fully open at 75F. In the event of a flood the internal floats lift to release the flood door to rotate open and relieve the hydrostatic pressure regardless of the louvers’ position, open or closed.
