It features a bottom-mount configuration and ships with a 3-wire Belimo actuator rated for a 35-second travel time, giving the system controller precise, reliable airflow modulation. The damper opening measures 12 inches wide by 8 inches tall, making it a common fit for residential and light-commercial duct runs. Licensed HVAC technicians install this component as part of a multi-zone control system, where individual dampers regulate conditioned air to specific areas or rooms.\u003c\/p\u003e\n\u003cp\u003eThis zone damper is suited for rectangular duct installations in residential and light-commercial forced-air systems. The bottom-mount actuator position simplifies access in tight duct chases or attic installations where side-mount access is limited. The 3-wire actuator wiring scheme supports spring-return or proportional control depending on the zone control board in use. It is commonly installed alongside zone control panels and thermostats as part of a complete zoning retrofit or new-construction zoning layout.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e12 x 8 inch rectangular damper opening fits standard duct sizes in residential and light-commercial applications\u003c\/li\u003e\n  \u003cli\u003eBottom-mount Belimo actuator allows installation in confined duct spaces where side or top access is restricted\u003c\/li\u003e\n  \u003cli\u003e35-second actuator travel time provides smooth, controlled airflow transitions that reduce system noise and pressure spikes\u003c\/li\u003e\n  \u003cli\u003e3-wire actuator wiring supports compatibility with a wide range of zone control boards\u003c\/li\u003e\n  \u003cli\u003ePackage dimensions of 14 x 16 x 8 inches accommodate the actuator assembly within the overall footprint\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 zoning systems using 3-wire Belimo-style actuators in residential and light-commercial forced-air HVAC applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed HVAC technician familiar with zoned forced-air systems and low-voltage control wiring. Power down the air handler and zone control panel before wiring the actuator to avoid damage to the control board. Verify duct dimensions and confirm the damper blade orientation matches airflow direction before fastening to the duct. Follow local mechanical codes and the zone controller manufacturer wiring diagram when making low-voltage connections.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDamper Opening Width\u003c\/strong\u003e: 12 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDamper Opening Height\u003c\/strong\u003e: 8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDamper Shape\u003c\/strong\u003e: Rectangular\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eActuator Mount Position\u003c\/strong\u003e: Bottom Mount\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 Travel Time\u003c\/strong\u003e: 35 seconds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Width\u003c\/strong\u003e: 14 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Height\u003c\/strong\u003e: 16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Depth\u003c\/strong\u003e: 8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 5.73 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: RM-1208-BM\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"IO HVAC CONTROLS","offers":[{"title":"Default Title","offer_id":67950393852210,"sku":"RM-1208-BM","price":243.82,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/745ecffd07cbe47f75f5847deb081dca_5555848c-4aa8-4729-b847-056343bd9b75.jpg?v=1791715965","url":"https:\/\/voomisupply.com\/products\/io-hvac-controls-rm-1208-bm-zone-damper-12x8-rectangular","provider":"Voomi Supply","version":"1.0","type":"link"}
