It ships with a Belimo three-wire actuator mounted on the bottom of the damper body, providing reliable open\/close control in forced-air distribution applications. The damper measures 32 inches in duct width by 16 inches in duct height, making it suitable for larger trunk or branch duct runs. At 8 pounds, it is a substantial assembly intended for permanent installation. Licensed HVAC technicians and sheet metal contractors are the primary installers for this type of equipment.\u003c\/p\u003e\u003cp\u003eThis zone damper is used in residential and light commercial zoning systems where individual areas or rooms require independent airflow control. It is suited for rectangular duct installations where a two-position, fully open or fully closed control strategy is applied. The bottom-mount actuator orientation is useful in installations where top or side access is restricted by overhead obstructions or adjacent ductwork. The Belimo three-wire actuator provides spring-return functionality, ensuring a fail-safe position on power loss.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eRectangular damper sized at 32 x 16 inches for larger duct applications\u003c\/li\u003e\n\u003cli\u003eTwo-position operation: fully open or fully closed airflow control\u003c\/li\u003e\n\u003cli\u003eIncludes Belimo three-wire actuator for reliable, spring-return actuation\u003c\/li\u003e\n\u003cli\u003eBottom-mount actuator configuration for restricted-access installations\u003c\/li\u003e\n\u003cli\u003eAssembled unit weighs 8 pounds for stable, permanent duct mounting\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or new-installation zone damper for rectangular ducted forced-air HVAC zoning systems accepting a two-position, three-wire actuator control signal.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a licensed HVAC technician or qualified sheet metal contractor. Shut down the air handler and disconnect power to the zoning control board before wiring or mounting the damper assembly. Secure the damper frame to the duct with sheet metal screws, ensuring the actuator is accessible for future service. Wiring must comply with applicable local mechanical and electrical codes, including NEC low-voltage wiring requirements where applicable.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDuct Width\u003c\/strong\u003e: 32 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDuct Height\u003c\/strong\u003e: 16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eActuator Type\u003c\/strong\u003e: Belimo 3 Wire\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eActuator Position\u003c\/strong\u003e: Bottom Mount\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDamper Operation\u003c\/strong\u003e: 2 Position\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDamper Shape\u003c\/strong\u003e: Rectangular\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUnit Height\u003c\/strong\u003e: 6.375 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUnit Depth\u003c\/strong\u003e: 32 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUnit Width\u003c\/strong\u003e: 16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 8 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: MD-3216-BM\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"IO HVAC CONTROLS","offers":[{"title":"Default Title","offer_id":67949757301042,"sku":"MD-3216-BM","price":461.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/75f2b6c2829c7454f6fbae3d993a1e9d_16da88be-63c8-4192-a4ca-271326b90504.png?v=1791700451","url":"https:\/\/voomisupply.com\/products\/io-hvac-controls-md-3216-bm-zone-damper-32x16-bottom-mount","provider":"Voomi Supply","version":"1.0","type":"link"}
