  • Directwire design works with select BEST® 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 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

Providing make-up air for exhaust devices is easy, controlling it is not - until now. BEST® 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. The MD8T is 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.
