York S1-2940-391P Vent Assembly

The York S1-2940-391P Power Vent Assembly is a high-performance OEM draft inducer motor replacement designed for commercial and residential HVAC systems. Operating on 115V with a 1/25 HP output, this assembly maintains a consistent 3000-3200 RPM to ensure positive pressure for the safe expulsion of flue gases. This unit is a direct replacement for York and Coleman series, including models 2940-390, 2940-391, and 2940A391. Built with a heavy-duty ventor blower assembly, it mitigates vibration and noise during startup and high-static cycles. Field technicians rely on its precise bolt-pattern alignment for furnace repair and ventilation troubleshooting. Its localized motor cooling and robust housing protect internal windings against high-heat exhaust gas environments, ensuring the S1-2940-391P provides reliable combustion air flow within the heat exchanger circuit. As a technician-grade draft inducer replacement, it secures the pressure switch circuit with verified airflow metrics across the 2940 series product line.

• Direct OEM Compatibility: Engineered specifically for York and Coleman 2940 series, replacing 2940B391 and 7021-7396.
• High-RPM Performance: 3000-3200 RPM operation ensures adequate static pressure to clear combustion byproducts efficiently.
• Contractor-Grade Durability: Robust motor construction manages the thermal stress of high-heat exhaust environments without performance degradation.
• Simplified Installation: Standard 115V electrical interface and precision-aligned mounting holes reduce field labor time during HVAC motor replacement.

Is the S1-2940-391P compatible with all 2940 series models?
Yes, this Power Vent Assembly is the current manufacturer-recommended replacement for several older 2940 iterations, including suffix variations like -390P and -390C.

Does this unit include the cooling fan for the motor?
The assembly is a pre-configured ventor motor unit designed to provide sufficient internal cooling for the 1/25 HP motor during continuous operation.

What are the electrical requirements for this draft inducer?
This HVAC inducer motor is rated for 115 Volts and approximately 1.3 Amps, making it compatible with standard furnace control boards in its class.
