It controls airflow to individual zones by opening and closing on demand from a zone controller or thermostat. The unit ships with a Belimo 3-wire actuator that operates on a 60-second cycle time, providing reliable and repeatable blade positioning. At 18 inches wide by 14 inches tall, this damper fits standard rectangular duct configurations common in residential and light commercial forced-air systems. Licensed HVAC technicians and sheet metal contractors are the typical installers for this type of equipment.\u003c\/p\u003e\n\u003cp\u003eThis damper is built as a direct replacement for Trane and American Standard rectangular zone damper applications. It is suited for residential and light commercial zoning installations where a dedicated zone damper with an integrated actuator is required. The 3-wire actuator wiring scheme supports both open and close command signals, making it compatible with most standard zone control boards used in forced-air ducted systems.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e18 x 14 inch rectangular damper fits standard duct openings of the same nominal size\u003c\/li\u003e\n  \u003cli\u003eBelimo 3-wire actuator included, no separate actuator purchase required\u003c\/li\u003e\n  \u003cli\u003e60-second actuator cycle time for controlled, smooth blade travel\u003c\/li\u003e\n  \u003cli\u003eDesigned as a drop-in replacement for Trane and American Standard zone damper positions\u003c\/li\u003e\n  \u003cli\u003eCompatible with standard low-voltage zone control wiring schemes\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a replacement zone damper for Trane and American Standard rectangular duct zoning applications.

Power down the zone control panel and any associated air handler equipment before wiring or mounting the damper. The 3-wire actuator requires low-voltage control wiring; follow the zone control board manufacturer's wiring diagram for proper terminal connections. Confirm duct dimensions and airflow direction before securing the damper in place.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDamper Width\u003c\/strong\u003e: 18 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDamper Height\u003c\/strong\u003e: 14 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 Cycle Time\u003c\/strong\u003e: 60 seconds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Width\u003c\/strong\u003e: 18 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Height\u003c\/strong\u003e: 25 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: 8 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-1814\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"IO HVAC CONTROLS","offers":[{"title":"Default Title","offer_id":67949753467186,"sku":"TD-1814","price":297.83,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/50bbd6f74b2edbde3fa9d504fe30cd5d_aeeff81a-451f-4903-b8da-62faafa4818b.jpg?v=1791700283","url":"https:\/\/voomisupply.com\/products\/io-hvac-controls-td-1814-rectangular-zone-damper-18x14","provider":"Voomi Supply","version":"1.0","type":"link"}
