Best Range Hoods 6-INCH AUTOMATIC MAKE-UP AIR DAMPER

Directwire Make-Up Air Dampers, when interlocked with slave dampers, open in unison to provide synchronized operation for kitchen, bath and whole house ventilation products. Wired to the transformer, using low voltage wiring, which signals the damper to open and close while the range hood is in operation. The intelligent design options ensure optimum performance in a variety of installations and applications.

Directwire design works with select range hoods to balance indoor air pressure by providing interlocked make-up air; damper opens automatically when fans are activated

Slave dampers (MD6S or MD8S) are interlocked to the the main automatic or universal make-up air damper and open in unison for synchronized operation. They close, along with the main damper, as soon as the range hood is powered off. Slave dampers can be ganged together to provide a cost effective means to provide for higher volumes of make-up air

Interlocked make-up air damper systems meet IRC Code requirements for make-up air with range hoods over 400 CFM

Interlocked make-up air systems avoid wasted energy associated with barometric solutions and do not let unwanted air into the home during heating or cooling activities so air pressure is equalized for a well-balanced environment

Fresh air wall caps are required for use with Make-Up Air Dampers
