Zone dampers are motorized or manually actuated blades installed inside ductwork to control airflow to individual zones in a zoned HVAC system. This damper helps balance heating and cooling distribution by opening or closing in response to thermostat or zone controller signals. At 11 pounds, it is a solid-construction unit suited for residential and light commercial forced-air applications. Installation is typically performed by a licensed HVAC technician during new zone system installation or as a replacement in an existing multi-zone setup.\u003c\/p\u003e\n\u003cp\u003eThe SD-2216 fits 22 x 16 duct openings and is appropriate for use in forced-air zoning systems where independent temperature control is needed across multiple areas of a building. It is well suited for residential split systems and light commercial air handlers where trunk or branch duct zoning is required. The overall unit dimensions of 27.75 inches depth, 16.75 inches width, and 6.75 inches height should be verified against available duct and plenum space prior to installation.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSized for 22 x 16 duct openings for direct in-duct installation\u003c\/li\u003e\n  \u003cli\u003eCompact housing at 16.75 inches wide, 6.75 inches tall, and 27.75 inches deep\u003c\/li\u003e\n  \u003cli\u003eWeighs 11 pounds for manageable handling during overhead or in-wall duct work\u003c\/li\u003e\n  \u003cli\u003eDesigned for use in multi-zone forced-air HVAC systems\u003c\/li\u003e\n  \u003cli\u003eAuxiliary designation supports secondary zone branch applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style auxiliary zone damper for use in residential and light commercial forced-air zoning systems with 22 x 16 duct openings.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eZone dampers are installed by licensed HVAC technicians. Before installation, shut down the air handler or furnace at the disconnect and verify the system is de-energized before working inside the duct. The damper must be mounted in accordance with the manufacturer orientation markings and secured to the duct using appropriate sheet metal fasteners and sealant per local mechanical codes. Low-voltage control wiring to the zone controller should be run and terminated per the zone control panel wiring diagram.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDuct Opening Size\u003c\/strong\u003e: 22 x 16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUnit Width\u003c\/strong\u003e: 16.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUnit Height\u003c\/strong\u003e: 6.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUnit Depth\u003c\/strong\u003e: 27.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 11 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: IO HVAC CONTROLS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: SD-2216\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"IO HVAC CONTROLS","offers":[{"title":"Default Title","offer_id":67949370835250,"sku":"SD-2216","price":437.22,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a6c59a381d0e8005908f8e0a8d621c71_bf7808f3-d158-4b8a-96a3-c317fa4b64ec.png?v=1791690461","url":"https:\/\/voomisupply.com\/products\/io-hvac-controls-sd-2216-auxiliary-zone-damper-22x16","provider":"Voomi Supply","version":"1.0","type":"link"}
