Cast iron construction provides durability and resistance to heat, making this damper appropriate for use in demanding HVAC and ventilation applications. It is sized at 8 inches and suited for installation in residential or light commercial settings where a robust, long-lasting damper is required. Licensed HVAC technicians and sheet metal contractors typically handle installation of this component as part of a duct system assembly or vent run.\u003c\/p\u003e\u003cp\u003eThis damper fits into 8-inch round duct or vent pipe applications where airflow regulation is needed. Common install scenarios include branch takeoffs, zone damper positions, and fresh-air or exhaust vent runs. The cast iron material makes it a practical choice for installations near heat sources or in locations where a plastic or lightweight metal damper would not hold up over time. It ships in a package quantity of 12 units, making it convenient for contractors stocking multiple units for ongoing work.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e8-inch diameter sizing fits standard round duct and vent pipe\u003c\/li\u003e\n\u003cli\u003eCast iron construction offers high heat resistance and long service life\u003c\/li\u003e\n\u003cli\u003eSuitable for airflow control in residential and light commercial HVAC systems\u003c\/li\u003e\n\u003cli\u003eAvailable in package quantities of 12 for contractor stocking\u003c\/li\u003e\n\u003cli\u003eDurable material resists warping and degradation in high-temperature environments\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or new-installation damper for 8-inch round duct and vent pipe systems in residential and light commercial HVAC and ventilation applications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a licensed HVAC technician or qualified sheet metal contractor in accordance with local mechanical codes and SMACNA guidelines. Power down or shut off the HVAC system before beginning work on any duct section. Ensure the damper is properly seated and secured in the duct run before restoring airflow. Do not force the damper blade if resistance is encountered during installation, as cast iron components can crack under excessive torque.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiameter\u003c\/strong\u003e: 8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Cast Iron\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 16.23 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 12\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUnit of Measure\u003c\/strong\u003e: EA\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: IMPERIAL MFG GROUP USA INC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: BM0053-A\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"IMPERIAL","offers":[{"title":"Default Title","offer_id":51558114754866,"sku":"BM0053-A","price":127.91,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b753744d5f4aadad3d50ae62f8b0a55d.jpg?v=1786403786","url":"https:\/\/voomisupply.com\/products\/imperial-mfg-group-usa-inc-bm0053-a-cast-iron-damper-8-in","provider":"Voomi Supply","version":"1.0","type":"link"}
