Io Hvac Controls sd-1806 Zone Damper 18x6 in Commercial

Product Description

The IO HVAC CONTROLS sd-1806 is a rectangular auxiliary zone damper sized at 18 inches by 6 inches, designed for commercial HVAC zoning applications. Zone dampers are installed inside ductwork to control airflow to individual zones, allowing a zoning control system to direct conditioned air where it is needed while blocking flow to unoccupied or satisfied zones. The sd-1806 fits into rectangular duct runs and works in conjunction with a zone control board and thermostat wiring to open and close on demand. Licensed HVAC technicians typically install and commission these dampers as part of a multi-zone forced-air system.

The sd-1806 is rated for commercial applications, making it suitable for light commercial buildings, office suites, retail spaces, and similar occupancies where multi-zone HVAC control is required. Its rectangular profile matches standard rectangular ductwork dimensions, simplifying integration into existing or new duct systems. The auxiliary designation indicates it is used as an additional damper alongside a primary zone control damper, expanding the zoning capacity of the system.
