Built from all-steel construction, it delivers the durability required for commercial and residential HVAC installations. The ring features a knob-operated worm gear mechanism, allowing precise manual adjustment of airflow without tools. HVAC technicians and sheet metal installers rely on this type of component to balance supply air distribution at the diffuser level. The steel body resists deformation under normal duct pressure conditions, and the brown finish is suited for ceiling or wall installations where the diffuser color must blend with the surrounding surface.\u003c\/p\u003e\u003cp\u003eThis damper ring is intended for use with round ceiling or wall diffusers in forced-air HVAC systems. It is sold in a package of 10 units, making it practical for new construction projects or multi-unit retrofits where multiple diffuser locations require damper control. The knob-operated worm gear allows the installing technician to set airflow restriction at each register point during system balancing. It is compatible with the AMERICAN METAL PRODUCTS 1500E6 round diffuser, as specified by the manufacturer.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAll-steel construction for durability in HVAC duct applications\u003c\/li\u003e\n\u003cli\u003eKnob-operated worm gear enables tool-free manual airflow adjustment\u003c\/li\u003e\n\u003cli\u003e6-inch diameter fits standard round diffuser openings\u003c\/li\u003e\n\u003cli\u003eBrown finish coordinates with matching round diffusers\u003c\/li\u003e\n\u003cli\u003eSold in a package of 10 units for multi-outlet installations\u003c\/li\u003e\n\u003cli\u003eDesigned for use with the AMERICAN METAL PRODUCTS 1500E6 round diffuser\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with the AMERICAN METAL PRODUCTS 1500E6 round diffuser, as stated by the manufacturer.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is typically performed by licensed HVAC technicians or sheet metal contractors during system commissioning or diffuser replacement. Power down the air handling unit and verify airflow has stopped before working at the diffuser opening. Secure the damper ring per the diffuser manufacturer instructions before attaching the diffuser face. Airflow balancing should be completed after all diffuser components are fully installed and the system is returned to operation.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiameter\u003c\/strong\u003e: 6 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColor\u003c\/strong\u003e: Brown\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShape\u003c\/strong\u003e: Round\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: All Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eActuation\u003c\/strong\u003e: Knob-Operated Worm Gear\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 10 units\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Weight\u003c\/strong\u003e: 5.5 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: AMERICAN METAL PRODUCTS\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 1800B6\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"AMERICAN METAL PRODUCTS","offers":[{"title":"Default Title","offer_id":51524186374450,"sku":"1800B6","price":162.65,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0d691dcdf1fdc41897c26fdc4cfa263a.jpg?v=1785445318","url":"https:\/\/voomisupply.com\/products\/american-metal-products-1800b6-round-damper-ring-6-inches","provider":"Voomi Supply","version":"1.0","type":"link"}
