Zoner dampers control airflow through individual zones in a ducted forced-air system, allowing independent temperature management in different areas of a building. At 16.75 inches in height, this round damper fits into standard round ductwork configurations. Installation is typically handled by licensed HVAC technicians as part of a zone control system setup or replacement service.\u003c\/p\u003e\n\u003cp\u003eThis damper is suited for forced-air zoning applications where round duct sections require motorized or manual airflow control. It is commonly installed in residential multi-zone systems and light commercial ducted HVAC setups where precise zone-by-zone airflow regulation is required. The 6616 carries the Aprilaire product line designation, which is associated with RESEARCH PRODUCTS zoning and air management components.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eRound shape for compatibility with standard round duct configurations\u003c\/li\u003e\n  \u003cli\u003e16.75-inch height accommodates common residential and light commercial duct sizing\u003c\/li\u003e\n  \u003cli\u003eDesigned for zoning applications requiring independent airflow control per zone\u003c\/li\u003e\n  \u003cli\u003eOEM-style construction consistent with RESEARCH PRODUCTS zoning system components\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or new-installation component for round-duct HVAC zoning systems using RESEARCH PRODUCTS zoner damper assemblies.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed HVAC technician.
