It accepts a 5\/8-inch or 1\/2-inch shaft, giving installers flexibility when pairing it with a separately sourced actuator. This damper controls airflow in zoned HVAC duct systems by opening or closing on a two-position signal, directing conditioned air to specific zones as commanded by a zone control board or thermostat. Licensed HVAC technicians typically specify and install this component during new duct construction or zone-system retrofits in larger residential or light commercial applications.\u003c\/p\u003e\n\u003cp\u003eThis damper is suited for rectangular duct systems requiring a large-format 36 x 24 inch blade size. Its bottom-mount configuration is appropriate for applications where actuator access from the bottom of the duct is required or preferred. Because no actuator is included, the installer selects and mounts a compatible two-position actuator to the 5\/8-inch or 1\/2-inch shaft to match the control system in use. This configuration is common in multi-zone forced-air systems using a dedicated zone control panel.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eLarge 36 x 24 inch blade size for high-volume rectangular duct applications\u003c\/li\u003e\n  \u003cli\u003eTwo-position operation for standard open\/close zone control\u003c\/li\u003e\n  \u003cli\u003eBottom-mount design for installations requiring bottom-side actuator access\u003c\/li\u003e\n  \u003cli\u003eDual shaft compatibility: accepts 5\/8-inch or 1\/2-inch actuator shafts\u003c\/li\u003e\n  \u003cli\u003eShips without actuator, allowing pairing with installer-specified two-position actuator\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 duct systems requiring a 36 x 24 inch two-position bottom-mount damper with a 5\/8-inch or 1\/2-inch shaft interface.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed HVAC technician in accordance with local mechanical codes and the system manufacturer guidelines. Power down the air handler and zone control panel before installing or wiring any damper or actuator components. Verify shaft size compatibility between the damper and the actuator before mounting. Ensure the damper blade moves freely through its full travel before restoring system power and testing zone operation.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDamper Size\u003c\/strong\u003e: 36 x 24 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMount Type\u003c\/strong\u003e: Bottom Mount\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOperation\u003c\/strong\u003e: Two-Position\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShaft Size\u003c\/strong\u003e: 5\/8 inch or 1\/2 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eActuator Included\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Width\u003c\/strong\u003e: 30 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Height\u003c\/strong\u003e: 39 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Depth\u003c\/strong\u003e: 7 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 22.04 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-3624\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"IO HVAC CONTROLS","offers":[{"title":"Default Title","offer_id":67950333821234,"sku":"HD-BM-NA-3624","price":504.75,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/dfc267a04b5a03da4e75e1fa41af6494_62129dc4-7efe-465e-adc7-b9f7aba00258.png?v=1791713822","url":"https:\/\/voomisupply.com\/products\/io-hvac-controls-hd-bm-na-3624-zone-damper-36x24","provider":"Voomi Supply","version":"1.0","type":"link"}
