This heavy-duty 1\/2 HP assembly operates at 1550 RPM on a 120V, single-phase power supply, providing the mechanical drive necessary to maintain consistent negative pressure in gas, oil, or solid-fuel venting systems. Built for professional HVACR applications, the kit includes a precision-balanced \u003cstrong\u003ePSC ball bearing motor\u003c\/strong\u003e pre-loaded with low-temperature lubricant rated down to -40°F, ensuring reliable startups in extreme rooftop environments. The \u003cstrong\u003e950-8603 replacement kit\u003c\/strong\u003e comes equipped with the necessary mounting plate and hardware to facilitate a clean drop-in installation, reducing labor time during critical service calls. By restoring the original \u003cstrong\u003edraft inducer performance\u003c\/strong\u003e, this motor kit helps prevent flue gas spillage and ensures the safe operation of boilers, water heaters, and industrial ventilation equipment. Its robust construction resists soot buildup and environmental corrosion, maintaining optimal airflow across high-static pressure applications.\u003c\/p\u003e\n\n\u003cstrong\u003eKey Benefits\u003c\/strong\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOEM Compatibility:\u003c\/strong\u003e Exact electrical and mechanical match for \u003cstrong\u003eTjernlund RT1500 draft indusers\u003c\/strong\u003e, eliminating field modifications.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eExtreme Environment Performance:\u003c\/strong\u003e Features a \u003cstrong\u003ePSC motor\u003c\/strong\u003e with specialized lubrication designed for reliable operation in temperatures as low as -40°F.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIntegrated Mounting Solution:\u003c\/strong\u003e Includes the factory-spec \u003cstrong\u003emounting plate\u003c\/strong\u003e and hardware to ensure proper alignment and vibration dampening.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHigh Operational Torque:\u003c\/strong\u003e 1\/2 HP motor provides the necessary 1550 RPM to handle high-static venting requirements and industrial-grade air volume.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIndustrial Durability:\u003c\/strong\u003e Roll steel frame and aluminum flange construction provide superior resistance to rooftop exposure and venting byproducts.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cstrong\u003eCommon Questions\u003c\/strong\u003e\n\u003cp\u003e\u003cstrong\u003eIs the 950-8603 compatible with the RT1500H series?\u003c\/strong\u003e\u003cbr\u003e\nYes, this motor kit is the designated factory replacement part for both the RT1500 and the high-output RT1500H models.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eDoes this motor require a specific capacitor or external control?\u003c\/strong\u003e\u003cbr\u003e\nThe 950-8603 is a \u003cstrong\u003ePermanent Split Capacitor (PSC)\u003c\/strong\u003e motor.
