Sterling HVAC 11507R04595 Draft Assembly

The Sterling HVAC 11507R04595 Power Vent Draft Assembly is a precision-engineered motor and blower kit essential for maintaining safe combustion cycles in commercial and residential unit heaters. Rated for 120 VAC at 60 Hz, this single-phase inducer assembly operates at 3000 RPM with a 1.5 Amp draw, providing the consistent negative pressure required to clear flue gases and prove the pressure switch. This OEM assembly features a high-performance motor with Class B insulation and durable ball bearings, designed to withstand the high-temperature environments of an exhaust airstream without premature failure.

For technicians in the field, this Sterling unit heater draft inducer is a direct drop-in replacement, reducing downtime during emergency service calls. The 37W blower motor assembly is built to manage exhaust flow efficiently, preventing backdrafting and ensuring the unit reaches ignition. Its heavy-duty construction is specifically calibrated for Sterling HVAC power venter systems, offering a reliable solution for persistent airflow codes or vibratory noise issues caused by worn-out fan wheels or failed motor windings.

• OEM Compatibility: Precision-fit for Sterling unit heaters, ensuring correct bolt alignment and flue connection.
• High-Speed Efficiency: Rated at 3000 RPM to provide immediate draft and stable pressure switch closure.
• Thermal Protection: Class B insulation safeguards the internal windings from the high-heat demands of constant venting.
• Quiet Operation: Balanced power vent assembly design minimizes vibration and resonance through the ductwork.
• Durable Bearings: Features high-grade ball bearings for extended mechanical life in vertical or horizontal mounting positions.

Is this a direct replacement for Sterling inducer motors?
Yes, the 11507R04595 is the official manufacturer replacement part, ensuring electrical and mechanical specifications match the original factory assembly.

What are the signs that my draft assembly is failing?
Mechanical rattling, high-pitched bearing squeals, or an "open pressure switch" fault code usually indicate that the ventor assembly is no longer reaching its rated 3000 RPM or has seized completely.

Does this assembly include the fan wheel and housing?
This is a complete power vent draft assembly, meaning it typically includes the motor, cooling fan, and centrifugal blower wheel mounted within the housing for a streamlined swap-out.
