Built for a 30 x 12 inch duct opening, this bottom-mount damper ships without an actuator, allowing the installer to pair it with a compatible actuator that meets the job's torque and control requirements. The 5\/8-to-1\/2 inch shaft accommodates standard actuator mounting hardware. At 12.04 pounds, the unit is sized for commercial-grade or larger residential duct runs where precise zone isolation is required. Licensed HVAC technicians performing zone system installations or retrofits are the primary installers.\u003c\/p\u003e\n\u003cp\u003eThis damper is suited for residential and light-commercial forced-air zoning applications where individual zones must be opened or closed based on thermostat demand. It is intended for rectangular duct systems requiring a bottom-mount configuration, typically in horizontal duct runs where the actuator mounts below the damper body. The no-actuator configuration is common in multi-zone projects where the contractor sources actuators separately to standardize control voltage or communication protocol across the system.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eTwo-position operation for open\/closed zone airflow control\u003c\/li\u003e\n  \u003cli\u003eBottom-mount design for horizontal duct installation where under-duct actuator placement is required\u003c\/li\u003e\n  \u003cli\u003eShips without actuator, allowing pairing with installer-selected two-position or modulating actuator\u003c\/li\u003e\n  \u003cli\u003e5\/8-to-1\/2 inch shaft for compatibility with standard actuator couplings\u003c\/li\u003e\n  \u003cli\u003eFits 30 x 12 inch rectangular duct openings\u003c\/li\u003e\n  \u003cli\u003eSturdy construction at 12.04 pounds for stable installation in larger duct runs\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 forced-air duct systems requiring a 30 x 12 inch two-position bottom-mount damper with a 5\/8-to-1\/2 inch actuator shaft.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed HVAC technician familiar with zoning system controls and ductwork. Shut down the air handler and disconnect power to the zone control board before mounting the damper or wiring any actuator. Select an actuator rated for the appropriate control voltage and torque for the duct size before completing the installation. Follow local mechanical codes and the zone control manufacturer's wiring guidelines when integrating with the zone panel.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDuct Size\u003c\/strong\u003e: 30 x 12 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMount Type\u003c\/strong\u003e: Bottom Mount\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eActuator Included\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShaft Size\u003c\/strong\u003e: 5\/8 to 1\/2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOperation Type\u003c\/strong\u003e: Two-Position\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 17 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 34 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: 12.04 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-BM-NA-3012\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"IO HVAC CONTROLS","offers":[{"title":"Default Title","offer_id":67949542506802,"sku":"HD-BM-NA-3012","price":320.13,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/dfc267a04b5a03da4e75e1fa41af6494_aff5db62-c5b6-4a8a-9c97-c515133d80f1.png?v=1791694733","url":"https:\/\/voomisupply.com\/products\/io-hvac-controls-hd-bm-na-3012-zone-damper-30x12","provider":"Voomi Supply","version":"1.0","type":"link"}
