Field Controls 46590504 - FAD-4 24V 4" Fresh Air Damper

Our Fresh Air Dampers remains closed until instructed to open by the Healthy Home System Control. It then opens to allow fresh air to be pulled into the return plenum where it's mixed with conditioned air, filtered and distributed to the rest of the house.

  • Durable, stainless steel construction
  • Motorized
  • Requires HHSC for activation
  • Energy efficient operation
  • Reliable, proven design
  • Remains closed when fresh air is not needed

How It Works
The Fresh Air Damper (FAD) is a motor driven damper activated by the Healthy Home System Control. When there is a call fro fresh air, the HHSC opens the damper allowing fresh air to enter the HVAC return. When the HHSC is satisfied, the damper is closed.
