Research Products 6616 Round Zoner Damper 16.75 Inches

Product Description

The RESEARCH PRODUCTS 6616 is a round zoner damper designed for use in residential and light commercial HVAC zoning systems. 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.

This 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.
