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.\u003c\/p\u003e\n\u003cp\u003eThe 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.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eRectangular form factor sized at 18 inches by 6 inches for direct duct integration\u003c\/li\u003e\n  \u003cli\u003eAuxiliary zone damper function allows expansion of existing zoning systems\u003c\/li\u003e\n  \u003cli\u003eRated for commercial HVAC applications\u003c\/li\u003e\n  \u003cli\u003eDesigned to operate with standard zone control boards and low-voltage thermostat wiring\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style auxiliary zone damper for commercial rectangular duct systems where 18-inch by 6-inch openings are present.
