Running at 3300 RPM, this \u003cstrong\u003epermanent split capacitor motor\u003c\/strong\u003e is built for the high-static pressure requirements of residential sidewall venting. This kit includes the necessary wheel and hardware to drop directly into \u003cstrong\u003eHS2, HSUL-2, HST-2\u003c\/strong\u003e, and \u003cstrong\u003eHS115-2\u003c\/strong\u003e units, ensuring the exact airflow specifications required to maintain safe negative pressure for gas and oil-fired equipment. When diagnosing a \u003cstrong\u003esidewall power venter\u003c\/strong\u003e that fails to prove draft, swapping the \u003cstrong\u003eTjernlund 950-1021 motor kit\u003c\/strong\u003e restores factory-standard velocity and system reliability. The steel construction and \u003cstrong\u003e3\/8 inch bore\u003c\/strong\u003e wheel are designed to withstand the thermal stresses of flue gas induction without the RPM drop-off common in generic replacements. Technicians should verify 115V supply and secure the fan proving switch sensing tube during installation to ensure proper safety interlock function.\u003c\/p\u003e\n\n\u003cstrong\u003eKey Benefits\u003c\/strong\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDirect OEM Compatibility\u003c\/strong\u003e: Fits \u003cstrong\u003eHS2, HSUL-2, HST-2, and HS115-2\u003c\/strong\u003e models without field modifications.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHigh-Torque Performance\u003c\/strong\u003e: The \u003cstrong\u003e3300 RPM\u003c\/strong\u003e operation maintains critical draft velocity for efficient combustion gas removal.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTotal Kit Solution\u003c\/strong\u003e: Includes both the motor and the precisely balanced blower wheel to eliminate vibration and bearing wear.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIndustrial Build Quality\u003c\/strong\u003e: Features a robust \u003cstrong\u003epermanent split capacitor\u003c\/strong\u003e design for continuous duty in high-heat environments.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cstrong\u003eCommon Questions\u003c\/strong\u003e\n\u003cstrong\u003eWhich power venter models use the Tjernlund 950-1021 motor?\u003c\/strong\u003e\nThis motor kit is the standard replacement for the \u003cstrong\u003eTjernlund HS2\u003c\/strong\u003e, as well as the \u003cstrong\u003eHSUL-2, HST-2, and HS115-2\u003c\/strong\u003e series sidewall power venters.\n\n\u003cstrong\u003eDoes this kit include the blower wheel?\u003c\/strong\u003e\nYes, the \u003cstrong\u003e950-1021\u003c\/strong\u003e is a complete motor and wheel assembly, ensuring you don't have to struggle with rusted or siezed wheels on the old motor shaft.\n\n\u003cstrong\u003eWill this motor fix a 'Fan Prover' fault?\u003c\/strong\u003e\nIf your power venter motor is failing to reach the necessary RPM to close the \u003cstrong\u003efan proving switch\u003c\/strong\u003e, installing this high-velocity motor kit typically resolves the draft-proving issue.\n\n\u003cp\u003e\u003cstrong style=\"color: red;\"\u003eThis item is not eligible for free shipping.\u003c\/strong\u003e\u003c\/p\u003e\n\n\u003cp\u003eDisclaimer: While we strive for 100% accuracy, product data and specifications are subject to change.
