Io Hvac Controls sd-1408 Auxiliary Zone Damper 14x8 in

Product Description

The IO HVAC CONTROLS sd-1408 is a rectangular auxiliary zone damper sized at 14 inches by 8 inches, designed for commercial HVAC zoning applications. Zone dampers control airflow to individual zones within a ducted forced-air system, opening and closing on a signal from a zone controller or thermostat. The sd-1408 installs in rectangular ductwork and works as an auxiliary damper, meaning it supplements a primary damper or controller to balance airflow across a multi-zone system. Licensed HVAC technicians and sheet metal contractors handle installation in commercial zoning setups.

The sd-1408 is specified for commercial HVAC zoning systems where rectangular ductwork carries conditioned air to multiple zones. Its 14-inch by 8-inch frame fits standard rectangular duct openings of that size. Auxiliary zone dampers are commonly installed in light commercial buildings, multi-tenant spaces, and larger residential applications that require individual zone airflow control. This damper fits within a broader zone control system that typically includes a zone controller, thermostats, and a bypass damper.

Installation Notes

Installation should be performed by a licensed HVAC technician or sheet metal contractor familiar with zoned forced-air systems. Shut down the air handling unit and de-energize the zone control system before installing or replacing any zone damper. Confirm duct dimensions match the 14 inch by 8 inch frame before securing the damper in place. Follow the zone controller manufacturer wiring instructions and all applicable local mechanical codes when connecting the damper actuator.
