iO HVAC Controls HD-MOTOR-RR Closed Fresh Air S/R Damper Actuator 24V

The IO HVAC Controls HD-MOTOR-RR S/R Closed Fresh Air S/R Damper Actuator is designed to control fresh air intake dampers in a ventilation unit in HVAC systems. It operates on a 24V control signal and moves the damper to an open position during powered operation, then returns it to a closed position when power is removed, ensuring airflow shutdown. It is placed in air handling units, rooftops, and fresh air ventilation assemblies where controlled outdoor air introduction is required. It operates as the damper blade, regulating ventilation airflow and supporting indoor air condition.
