Product HighlightsMake-Up Air Dampers, when interlocked with slave dampers, open in unison to provide synchronized operation for kitchen, bath and whole house ventilation products. They are 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.
