Running on 115 volts at 60 Hz, this blower draws between 0.3 and 0.6 amps and operates in the 2800 to 3200 RPM range, delivering consistent performance across its rated speed band. Rated at 1\/20 HP, it is sized for residential gas furnace applications. Licensed HVAC technicians typically handle installation and replacement of this component during planned maintenance or heat exchanger system service.\u003c\/p\u003e\u003cp\u003eThis combustion air blower assembly is intended for use in residential gas furnace systems where induced-draft or forced-draft combustion air delivery is required. It is suited for installations where the OEM blower assembly has reached end of service life or failed during heating season. The 115-volt single-phase power supply makes it compatible with standard residential electrical configurations common in North American furnace applications.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eOperates at 115 volts, 60 Hz for standard residential power compatibility\u003c\/li\u003e\n\u003cli\u003eSpeed range of 2800 to 3200 RPM supports reliable draft performance\u003c\/li\u003e\n\u003cli\u003eLow current draw of 0.3 to 0.6 amps reduces electrical load on furnace control circuit\u003c\/li\u003e\n\u003cli\u003e1\/20 HP motor rating appropriate for residential induced-draft furnace applications\u003c\/li\u003e\n\u003cli\u003eAssembly format simplifies direct swap replacement without fabrication\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement combustion air blower assembly for residential gas furnace systems requiring a 115-volt induced-draft or forced-draft blower.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a licensed HVAC technician in accordance with applicable local mechanical codes and the furnace manufacturer service documentation. Disconnect all electrical power to the furnace and allow the system to cool before removing the existing blower assembly. Verify that the replacement assembly mounting configuration and electrical connections match the original before powering the system back on. Do not operate the furnace without the blower assembly properly secured and all safety interlocks confirmed functional.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePower\u003c\/strong\u003e: 1\/20 HP\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVoltage\u003c\/strong\u003e: 115 volts\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFrequency\u003c\/strong\u003e: 60 Hz\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAmperage\u003c\/strong\u003e: 0.3 to 0.6 amps\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpeed\u003c\/strong\u003e: 2800 to 3200 RPM\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: ALLIED AIR\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 81w45\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ALLIED AIR","offers":[{"title":"Default Title","offer_id":51467378590002,"sku":"81W45","price":435.53,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/313945411.jpg?v=1783902832","url":"https:\/\/voomisupply.com\/products\/allied-air-81w45-combustion-air-blower-assembly-1-20-hp","provider":"Voomi Supply","version":"1.0","type":"link"}
