It draws 0.73 amps at 115 volts, spins at 2800 RPM, and consumes a maximum of 83 watts. A built-in pressure-sensing switch activates the fan automatically when positive pressure is detected in the duct line, then shuts the unit off once duct pressure returns to normal. A 5-foot power cord is included. Licensed HVAC technicians and dryer vent specialists are the primary installers of this unit in both residential and light commercial applications.\u003c\/p\u003e\n\u003cp\u003eThe dbf4xl is suited for installations where dryer exhaust duct runs exceed recommended lengths or include multiple elbows that reduce airflow velocity. It is installed inline within the dryer duct to restore adequate exhaust capacity, helping reduce drying cycle times and lint accumulation in long runs. The metal housing is appropriate for dryer exhaust applications where local codes require noncombustible duct materials.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003ePressure-sensing switch activates fan on positive duct pressure and shuts off automatically when pressure normalizes\u003c\/li\u003e\n  \u003cli\u003eOperates at 2800 RPM for sustained airflow boost through extended duct runs\u003c\/li\u003e\n  \u003cli\u003eMetal construction suitable for dryer exhaust duct applications requiring noncombustible materials\u003c\/li\u003e\n  \u003cli\u003eIncludes a 5-foot power cord for straightforward electrical connection\u003c\/li\u003e\n  \u003cli\u003eLow current draw at 0.73 amps keeps operating costs minimal\u003c\/li\u003e\n  \u003cli\u003e5-year warranty provides long-term serviceability assurance\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style inline booster for 4-inch residential and light commercial dryer exhaust duct systems.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation of dryer booster fans is typically performed by a licensed HVAC technician or dryer vent specialist. Always disconnect power to the dryer and the booster fan circuit before beginning any work. The unit must be installed in accordance with local mechanical codes and the dryer manufacturer's venting requirements. Do not install on duct runs that carry anything other than dryer exhaust.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eProduct Type\u003c\/strong\u003e: Dryer Booster Fan\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDuct Size\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVoltage\u003c\/strong\u003e: 115 volts\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRPM\u003c\/strong\u003e: 2800\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMax Watts\u003c\/strong\u003e: 83 watts\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMax Amps\u003c\/strong\u003e: 0.73 amps\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHousing Material\u003c\/strong\u003e: Metal\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePower Cord\u003c\/strong\u003e: 5 feet included\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWarranty\u003c\/strong\u003e: 5 years\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: FANTECH\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: dbf4xl\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"FANTECH","offers":[{"title":"Default Title","offer_id":51467527422258,"sku":"DBF4XL","price":308.12,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/313948017.jpg?v=1783906306","url":"https:\/\/voomisupply.com\/products\/fantech-dbf4xl-dryer-booster-fan-4-inch-115v","provider":"Voomi Supply","version":"1.0","type":"link"}
