Aprilaire 6609w3 Round Zone Damper Power Open Power Closed 9 Inches 3 Wire

Product Description

The Aprilaire 6609w3 is a 9 inch round zone damper designed for use in residential and light commercial HVAC zoning systems. It operates on a power open, power close motor configuration with 3-wire control, making it fully automatic and compatible with most zone control panels on the market. HVAC technicians use zone dampers like this one to direct conditioned air to specific areas of a building. This allows each zone to receive heating or cooling independently, improving comfort and energy efficiency throughout the structure. The 6609w3 fits 9 inch round duct, and it works with both rigid metal ductwork and flexible duct. This versatility makes it a practical choice across a wide range of residential retrofit and new construction zoning applications. The damper is built from galvanized steel, which resists corrosion and holds up well inside duct systems over years of continuous use. Adjustable blade positioning gives the installer control over airflow balance, and an integrated foam seal reduces air leakage when the damper is in the closed position. Operating at 24 volts, the 6609w3 is safe and straightforward to wire into standard low-voltage HVAC control systems. The power close motor means the damper does not rely on a spring return to shut. Instead, it uses motor power to open and to close, providing a more reliable and precise seal. This is especially important in systems where tight airflow control is critical. Aprilaire backs this damper with a 5-year warranty, reflecting the durability built into each unit. Whether you are installing a new multi-zone system or upgrading an existing one, the 6609w3 delivers consistent performance in air quality and comfort control applications.
