Dual-Function Custom Multi-Frame


Custom Multi-Frames are more efficient than a single unit and are a great solution for large amounts of square footage requiring flood protection as well as situations where there is not enough wall space to fit single units.  Choose between a robust, one-piece frame, or a lighter more economical frame depending on the configuration.  Multi-Frames can be designed from a 2x2 up to a 6x3 configuration to fit the needs of your project.

Application

These vents are used for a home with a crawlspace or any enclosed area that desires natural air ventilation and flood protection.

Flood Protection

The vent door is latched closed until it comes in contact with flood water. Entering flood water lifts the patented internal floats which unlatch and allow the door to rotate open. This allows the flood water to automatically enter and exit through the frame opening, relieving the pressure from the foundation walls. Certified flood debris clearance is demonstrated with a 3” diameter opening when the flood door is activated.

Ventilation

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
