Sized at 18 inches by 6 inches with a bottom-mount configuration, this damper installs into ductwork to control airflow distribution across individual zones. The bottom-mount design positions the actuator along the lower edge of the duct opening, accommodating installations where overhead clearance is limited. Licensed HVAC technicians and commercial mechanical contractors are the primary installers for this type of component.\u003c\/p\u003e\n\u003cp\u003eThis damper is suited for commercial zoning applications where independent temperature control is required across multiple areas or rooms. The rectangular form factor fits standard rectangular duct sections. Bottom-mount orientation is selected when the installation layout requires actuator access from below the duct, a common requirement in dropped-ceiling commercial environments and plenum spaces where service access is restricted from the sides or top.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e18 inches by 6 inches rectangular damper body fits standard commercial duct openings\u003c\/li\u003e\n  \u003cli\u003eBottom-mount actuator position supports installations with limited overhead or side clearance\u003c\/li\u003e\n  \u003cli\u003eAuxiliary zone configuration allows integration into multi-zone commercial HVAC systems\u003c\/li\u003e\n  \u003cli\u003eRectangular shape compatible with standard rectangular ductwork construction\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style auxiliary zone damper for commercial rectangular ductwork applications requiring bottom-mount actuator placement.\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 SMACNA ductwork standards. Shut down the air handling unit and de-energize all low-voltage control wiring before beginning damper installation. Verify duct opening dimensions match the damper frame size before securing in place. Confirm actuator wiring connections comply with the zone control panel manufacturer specifications before restoring power.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eProduct Type\u003c\/strong\u003e: Damper\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSize\u003c\/strong\u003e: 18 inches x 6 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShape\u003c\/strong\u003e: Rectangular\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMount Type\u003c\/strong\u003e: Bottom Mount\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: Commercial\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: sd-1806-bm\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"IO HVAC CONTROLS","offers":[{"title":"Default Title","offer_id":51268955996466,"sku":"SD-1806-BM","price":324.17,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/308910763.jpg?v=1780710945","url":"https:\/\/voomisupply.com\/products\/io-hvac-controls-sd-1806-bm-zone-damper-18x6-in-bottom-mount","provider":"Voomi Supply","version":"1.0","type":"link"}
