The model designation 2VP65 identifies this as a two-groove variable pitch sheave with a nominal 6.5-inch outside diameter, and it is bored to accept a 1-1\/8-inch shaft. Variable pitch sheaves allow technicians to adjust fan speed without changing belts or pulleys, making them a standard solution for airflow balancing during system commissioning or seasonal adjustment. Licensed HVAC mechanics and sheet metal installers are the primary trades who install and adjust this type of component.\u003c\/p\u003e\u003cp\u003eThis pulley is suited for use in residential and light commercial forced-air systems, including air handling units, belt-drive blower assemblies, and packaged rooftop units. The 2VP65 designation is widely used on draw-through and blow-through fan sections where belt-drive motors require pitch adjustment to meet design CFM targets. It mounts to a standard 1-1\/8-inch motor or blower shaft and accepts standard V-belts matched to a 2VP sheave profile.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eTwo-groove variable pitch sheave allows field adjustment of fan speed and airflow\u003c\/li\u003e\n\u003cli\u003e1-1\/8-inch bore fits standard HVAC blower and motor shaft sizes\u003c\/li\u003e\n\u003cli\u003e2VP65 sheave profile compatible with standard V-belt drives\u003c\/li\u003e\n\u003cli\u003eNominal 6.5-inch diameter suitable for typical blower-to-motor drive ratios\u003c\/li\u003e\n\u003cli\u003eField-adjustable pitch reduces need for multiple fixed sheaves during system balancing\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement variable pitch sheave for belt-drive blower assemblies in residential and light commercial HVAC air handling applications requiring a 2VP65 1-1\/8-inch bore sheave.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified HVAC technician or mechanical contractor. Disconnect and lock out power to the air handling unit before removing or installing any drive components. After mounting the sheave and installing the belt, verify belt tension and alignment with a straightedge before restoring power. Pitch adjustment should be made only when the unit is de-energized, following the manufacturer's adjustment procedure for the specific sheave design.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSheave Model\u003c\/strong\u003e: 2VP65\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBore Size\u003c\/strong\u003e: 1-1\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGroove Configuration\u003c\/strong\u003e: 2-groove variable pitch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNominal Outside Diameter\u003c\/strong\u003e: 6.5 inches\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: LAU\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: G078104828\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"LAU","offers":[{"title":"Default Title","offer_id":51383955390770,"sku":"G078104828","price":293.95,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/G078104828.jpg?v=1782613081","url":"https:\/\/voomisupply.com\/products\/lau-g078104828-variable-pitch-pulley-2vp65-1-1-8-bore","provider":"Voomi Supply","version":"1.0","type":"link"}
