Description
The IO HVAC Controls D-16 16″ 2‑Wire Round Zone Damper 24 V is an airflow control component designed to regulate air distribution within HVAC systems. It features a round frame and operates with an actuator to open or close the damper blade in response to control signals from thermostats or controllers. Mounted in main or branch ductwork, the damper modulates airflow to individual zones or spaces, enabling balanced distribution of conditioned air and improved comfort control. It works as part of a zoned control strategy to route airflow where needed and minimize unnecessary heating or cooling.
