Factory Authorized Parts™ 50DK406816 Inducer Blower Assembly | 460V | 3450 RPM | 1/16 HP | 3-Phase | OEM Draft Inducer

The Factory Authorized Parts™ 50DK406816 serves as the critical "lungs" of your commercial furnace's combustion cycle, acting as the primary draft inducer assembly. This OEM-focused module is the specific component responsible for pulling air through the burners and exhausting combustion gases safely out of the vent pipe. Engineered for high-voltage Carrier and Bryant commercial rooftop units, this assembly ensures the system's "brain" (the pressure switch) can maintain the precise negative pressure required to initiate the ignition sequence. Replacing a failing or noisy motor with this genuine 460V assembly restores factory-spec airflow, ensuring an optimal air-to-fuel ratio and preventing safety lockouts.

Key Features

• Complete OEM Inducer Kit: Specifically engineered to replace part number 50DK406816, including the motor, blower wheel, housing, and gasket for a seamless "drop-in" installation.
• High-Voltage 460V Performance: Purpose-built for industrial 460V power systems, delivering the high-torque start required for heavy-duty commercial heating cycles.
• Dynamic Vibration Resolution: Factory-balanced to eliminate grinding, humming, or screeching noises that indicate worn bearings or a failing combustion blower.
• Sealed Ball Bearing Design: Features a permanently lubricated motor rated for continuous duty, reducing friction and extending the operational life in demanding rooftop environments.
• Advanced Combustion Safety: Precision-calibrated to maintain the draft required to close safety pressure switches, ensuring the system only ignites when exhaust gases are moving safely.

🛠️ HVAC Depot Pro Tip

Take a Picture First: Before removing the old inducer, photograph the wiring harness and the vacuum tubing connections to the pressure switch. Because 460V commercial units often use complex wiring, a visual reference ensures the new 50DK406816 is phased correctly. Conduct a diagnostic check by inspecting the collector box for cracks or debris before mounting the new assembly; always use the included high-temp gasket to ensure an airtight seal, as even a minor air leak can prevent the pressure switch from closing.
