Reznor 220780 Venter Assembly

The Reznor 220780 Venter Assembly is a critical 115V combustion air blower designed for precision airflow management in UDAP-100, UDAP-125, UDAS-100, and UDAS-125 unit heaters. This OEM replacement venter motor, manufactured by Nortek, operates at 2950 RPM and provides the necessary static pressure to exhaust flue gases safely through the vent pipe. As an HVAC inducer blower, it ensures the pressure switch closes during the startup sequence, maintaining the safety chain for consistent gas-fired furnace operation. This specific Venter Assembly w/o Housing consists of the motor and wheel assembly, allowing for a 115 volt 60Hz drop-in replacement while utilizing the existing blower scroll and orifice plate. Its thermally protected Class B insulation ensures reliable performance in high-temperature HVAC venting environments. For technical accuracy, verify that your unit heater model matches the 100K to 125K BTU capacity range before installation to ensure proper combustion airflow and heating system efficiency.
