It operates on a powered-open actuation model, meaning the actuator drives the blade to the open position under power and returns to closed when power is removed. This makes it well suited for fail-closed zoning applications where duct closure on power loss is the preferred safety state. The damper fits a 30-inch by 12-inch duct opening and is installed by HVAC technicians as part of a multi-zone ducted air distribution system. At 12.16 pounds, it is a robust assembly intended for permanent installation in residential or light commercial ductwork.\u003c\/p\u003e\n\u003cp\u003eThe HD-3012-PO is used in ducted forced-air systems where individual zones require independent airflow control. Typical installations include residential multi-zone systems with a dedicated zone control board, as well as light commercial applications where supply trunk lines serve separate building zones. The damper is mounted directly in the supply or branch duct and wired back to a zone controller or control panel. It is appropriate for rectangular duct runs requiring a 30-inch by 12-inch damper section.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003ePowered-open, spring-return-to-closed actuation for fail-closed operation\u003c\/li\u003e\n  \u003cli\u003eSized for a 30-inch by 12-inch rectangular duct opening\u003c\/li\u003e\n  \u003cli\u003eTwo-position control  -  fully open or fully closed, no modulating required\u003c\/li\u003e\n  \u003cli\u003eRobust construction at 12.16 pounds for long-term in-duct service\u003c\/li\u003e\n  \u003cli\u003eCompatible with standard low-voltage zone control systems\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or new-installation zone damper for rectangular ducted forced-air HVAC systems requiring a 30-inch by 12-inch two-position powered-open damper.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed HVAC technician. De-energize the zone control system and disconnect power to the air handler or furnace before beginning damper installation. The damper is mounted inline in the duct and secured per the duct system manufacturer recommendations; wiring to the zone controller should follow NEC low-voltage wiring guidelines. Confirm actuator rotation direction and blade position before restoring power to the system.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDuct Opening Size\u003c\/strong\u003e: 30 inches x 12 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eActuation Type\u003c\/strong\u003e: Powered Open, Spring Return Closed\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDamper Style\u003c\/strong\u003e: Rectangular Two-Position\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 15 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 37 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDepth\u003c\/strong\u003e: 8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 12.16 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: HD-3012-PO\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"IO HVAC CONTROLS","offers":[{"title":"Default Title","offer_id":67950445625650,"sku":"HD-3012-PO","price":384.62,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a1b50dcb988a745a6303af3d0b54d5d6_33ddb0bf-93ee-4bae-a45f-69259b113afb.jpg?v=1791718002","url":"https:\/\/voomisupply.com\/products\/io-hvac-controls-hd-3012-po-zone-damper-30x12-powered-open","provider":"Voomi Supply","version":"1.0","type":"link"}
