Built from zinc with a black finish, this pulley transfers rotational force from the motor to the blower assembly, keeping airflow consistent across the system. At 11 inches in diameter and weighing 2.1 pounds, it is a direct-replacement component suited for standard residential and light commercial blower setups. HVAC technicians and evaporative cooler service pros install this part during routine maintenance or when a worn or damaged pulley causes belt slippage or uneven blower performance.\u003c\/p\u003e\u003cp\u003eThis pulley is commonly used in evaporative cooler blower assemblies and forced-air ventilation units that rely on belt-driven blower systems. It is appropriate for residential and light commercial applications where a C-velocity belt configuration is specified. The black zinc construction resists corrosion in outdoor and high-humidity environments typical of evaporative cooler installations.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e11-inch diameter suits standard belt-driven blower assemblies\u003c\/li\u003e\n\u003cli\u003eZinc construction provides corrosion resistance for outdoor and humid environments\u003c\/li\u003e\n\u003cli\u003eBlack finish reduces surface oxidation over time\u003c\/li\u003e\n\u003cli\u003eC-velocity belt groove configuration for proper belt seating and power transfer\u003c\/li\u003e\n\u003cli\u003eManufactured in the United States\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement blower pulley for belt-driven evaporative cooler and forced-air ventilation blower assemblies requiring an 11-inch C-groove pulley.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified HVAC technician or evaporative cooler service professional. Disconnect all electrical power to the unit and relieve any tension on the existing belt before removing the old pulley. Verify shaft bore size and belt groove type match the replacement pulley before installation. Reinstall and tension the belt according to the equipment manufacturer specifications before restoring power.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Type\u003c\/strong\u003e: Blower Pulley\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Zinc\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColor\u003c\/strong\u003e: Black\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiameter\u003c\/strong\u003e: 11 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDepth\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 2.1 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBelt Velocity\u003c\/strong\u003e: C\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackaging Type\u003c\/strong\u003e: Boxed\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCountry of Origin\u003c\/strong\u003e: United States\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: DIAL\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 6330\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"DIAL","offers":[{"title":"Default Title","offer_id":51138851668274,"sku":"6330","price":24.01,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/305531197.webp?v=1778264658","url":"https:\/\/voomisupply.com\/products\/dial-6330-blower-pulley-11-inches-zinc-black","provider":"Voomi Supply","version":"1.0","type":"link"}
