Aprilaire 6608w3 8 Inch Round Power Open Power Closed Zoning Damper 3 Wire

Product Description

The Aprilaire 6608w3 is an 8 inch round zoning damper designed for power open and power closed operation in residential and light commercial HVAC zoning systems. This 3 wire damper gives HVAC technicians precise control over airflow in forced air duct systems. It is built from a combination of plastic and steel for durability and long service life. The 6608w3 operates on 24 volts, making it compatible with standard low voltage HVAC control systems used across most residential installations. Zoning dampers like this one are a core component in multi zone HVAC setups. They open and close inside the ductwork to direct conditioned air only to the zones that call for it. This improves comfort, reduces energy waste, and gives homeowners individual temperature control in different areas of the home. The power open and power closed design means the damper uses motor power to move in both directions. This is different from a spring return damper, which only uses power in one direction. Power open and power closed operation gives the zone controller more reliable and repeatable positioning in systems where precise damper behavior is critical. The 6608w3 fits an 8 inch round duct, one of the most common duct diameters found in residential HVAC systems. At 12 inches in length and approximately 11.75 inches in height, it is sized for straightforward installation in standard duct runs. The unit weighs 6 pounds. Aprilaire has manufactured HVAC accessories and indoor air quality products in the United States since 1954. This damper carries a 5 year warranty, reflecting the brand's commitment to quality and professional grade performance. HVAC technicians and contractors installing or servicing zoning systems will find this damper a reliable choice for new construction or retrofit zoning projects.
