A direct replacement for the Dayton 2C916 blower motor, the 1TDR1 delivers 168 CFM of airflow at dual speeds (1400/1650 RPM) on standard 115V, 50/60 Hz power. Ball bearing construction, Class B insulation, and built-in automatic overload protection make this a reliable, long-service drop-in for HVAC units, furnace air handlers, and ventilation equipment. Also catalogued as NBK Parts 20514.
When a blower motor fails in a furnace, air handler, or ventilation unit, a direct-fit replacement avoids costly rewiring and bracket fabrication. The 1TDR1 matches the mounting footprint, shaft diameter, and electrical requirements of the original Dayton 2C916, so installation is straightforward for anyone comfortable with basic electrical work.
The forward-curved squirrel cage wheel (5-1/8 in diameter, 1-7/8 in wide) moves air efficiently at low static pressures -- typical of furnace air-circulation and HVAC fan applications. Clockwise rotation (viewed from the inlet side) matches the orientation of the original unit.
Runs at 1400 RPM (low) or 1650 RPM (high), drawing only 0.22 A and 0.25 A respectively -- efficient and easy on electrical systems.
Permanently lubricated ball bearings deliver longer service life and quieter operation than sleeve-bearing alternatives in continuous-duty applications.
Integrated thermal overload protector shuts the motor down if it overheats and automatically resets, protecting both the motor and connected equipment.
Class B rated windings handle continuous temperatures up to 266 deg F (130 deg C), well above the 104 deg F max inlet air temperature spec.
The 1TDR1 is a verified direct replacement for the Dayton 2C916 blower motor. It is also sold under the NBK Parts number 20514. If your existing motor carries either of those numbers on its label, the 1TDR1 is the correct replacement.
This motor family is commonly found in residential and light-commercial HVAC equipment, gas furnace air handlers, evaporative cooler blowers, and enclosed ventilation units where a compact, single-inlet forward-curved blower is required.
