Sized at 24 inches by 20 inches, it ships pre-assembled with a Belimo 3-wire actuator mounted to the bottom of the damper body. The actuator operates on a 60-second stroke cycle, providing reliable and repeatable airflow control across independently conditioned zones. Licensed HVAC technicians install this damper directly into ductwork as part of a zone control system, replacing failed or absent zone dampers without requiring separate actuator procurement.\u003c\/p\u003e\n\u003cp\u003eThis damper is intended for use in Trane and American Standard rectangular duct zone control applications. The bottom-mount Belimo actuator configuration suits installations where overhead clearance is limited or where bottom access is preferred during service. The 24-inch by 20-inch face size addresses larger trunk or branch duct runs common in commercial-grade residential and small commercial zoning layouts. It is appropriate for new zoning installations and direct replacements in existing Trane and American Standard compatible zone systems.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e24 inch by 20 inch rectangular damper face for larger duct applications\u003c\/li\u003e\n  \u003cli\u003ePre-installed Belimo 3-wire actuator eliminates separate actuator sourcing\u003c\/li\u003e\n  \u003cli\u003e60-second actuator stroke cycle for smooth, controlled damper movement\u003c\/li\u003e\n  \u003cli\u003eBottom-mount actuator placement accommodates restricted overhead clearance\u003c\/li\u003e\n  \u003cli\u003eCompatible with Trane and American Standard zone control systems\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with Trane and American Standard rectangular zone control systems as a direct-replacement zone damper in 24-inch by 20-inch duct openings.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed HVAC technician familiar with low-voltage zone control wiring and duct modification work. Shut down the air handler and de-energize the zone control panel before beginning installation. Ensure the duct opening is sized to match the damper face dimensions and that adequate clearance exists on the bottom side of the duct for the actuator body and wiring connections. Follow the zone control panel manufacturer's wiring diagram for the 3-wire Belimo actuator connection.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDamper Width\u003c\/strong\u003e: 24 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDamper Height\u003c\/strong\u003e: 20 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 Stroke Time\u003c\/strong\u003e: 60 seconds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eActuator Mount Position\u003c\/strong\u003e: Bottom Mount\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Width\u003c\/strong\u003e: 26 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Height\u003c\/strong\u003e: 28 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: 14 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: TD-2420-BM\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"IO HVAC CONTROLS","offers":[{"title":"Default Title","offer_id":67952079143218,"sku":"TD-2420-BM","price":441.3,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/50bbd6f74b2edbde3fa9d504fe30cd5d_fa16b286-e1c4-4de2-8da0-535e1620efa5.jpg?v=1791746016","url":"https:\/\/voomisupply.com\/products\/io-hvac-controls-td-2420-bm-zone-damper-24x20-belimo","provider":"Voomi Supply","version":"1.0","type":"link"}
