The IO HVAC CONTROLS SC-ZD-1408 is a modulating zone damper designed for commercial HVAC zoning applications. It controls airflow within a ducted system by varying blade position across a range of positions rather than operating in a simple open-closed mode. This modulating action allows precise airflow balancing across multiple zones, improving comfort and system efficiency. The damper fits a 14 x 8 inch duct opening and weighs 6.9 pounds. It is installed by licensed HVAC technicians as part of a commercial zoning system, typically paired with a zone controller and actuator assembly.
This damper is suited for commercial zoning installations where variable airflow control is required across multiple conditioned zones. Typical applications include light commercial buildings, multi-zone rooftop unit systems, and retrofitted commercial zoning setups. The 14 x 8 inch duct size targets medium-capacity commercial trunk or branch duct runs. Its modulating design makes it appropriate for systems where static pressure management and zone-by-zone airflow adjustment are critical to system performance.
Designed as an OEM-style modulating zone damper for commercial ducted HVAC zoning systems requiring a 14 x 8 inch damper. Verify actuator signal type and control board compatibility before installation.
Installation should be performed by a licensed HVAC technician familiar with commercial zoning systems. Shut down the air handling unit and de-energize all low-voltage control wiring before installing or replacing a zone damper. Confirm that the control signal output from the zone controller matches the actuator requirements for this damper. Follow local mechanical codes and manufacturer wiring diagrams when connecting the damper actuator to the zone control panel.
