Fresh Air Kit
Here's another all-in-one fresh air connection to a forced air heating system. The FAI-6 Fresh Air System provides all the components you need except the duct. It connects to the return side of a forced air, central furnace and provides automatic control of outside air supply. The furnace blower draws in outside air and distributes it through the ducts. The system includes: timer control Module, 24 volt spring return damper, volume control damper, intake hood, adjustable volume damper, control cables and a take-off flange. The control unit connects to a 120 volt power supply and provides 24 volt output for the damper and furnace blower relay. The control also provides 115 volt power for an exhaust fan. In addition to the built-in timer, you can add a separate control, such as a dehumidistat.
