The Dayton 1TDR5 is a direct-replacement centrifugal blower motor built to swap in where the Dayton 2C069 was originally installed. Running on 115V at 50 or 60 Hz, it delivers 312 CFM of airflow at either 1280 or 1380 RPM depending on frequency, making it a reliable choice for HVAC air handlers, furnace blowers, and equipment ventilation systems that require a compact, dual-speed-rated motor with ball-bearing construction and automatic overload protection.
When an older Dayton 2C069 blower motor fails, sourcing an exact replacement can be frustrating. The 1TDR5 resolves that by matching the critical performance parameters -- voltage, CFM, RPM, and physical envelope -- so you can restore proper airflow without fabricating new mounting hardware or modifying ductwork connections.
Ball-bearing construction keeps the motor running quietly and extends service life compared to sleeve-bearing designs, particularly in applications where the motor runs for extended daily cycles. Class B insulation handles operating temperatures up to 130 deg C (266 deg F) winding temperature, and the automatic overload protector shuts the motor down if it runs hot rather than letting it burn out.
Moves 312 cubic feet per minute at rated speed -- enough for residential-scale air handlers, furnace blower decks, and equipment cooling cabinets.
Ball bearings reduce friction and wear for longer service life and quieter operation versus sleeve-bearing motors in the same frame size.
Operates on both 50 Hz and 60 Hz supplies. Runs at 1280 RPM on 50 Hz systems and 1380 RPM on 60 Hz -- no derating or rewiring needed.
Internal thermal overload protector cuts power if the motor overheats, protecting the winding and reducing fire risk in enclosed installations.
This motor is the catalogued successor to Dayton model 2C069. The housing dimensions, flange bolt pattern, shaft diameter, inlet size, and outlet geometry are matched to the original so the swap does not require adapter plates or duct modifications. Also sold under NBK Parts number 20529, which is the same unit.
The 1TDR5 supports both clockwise (CW) and counter-clockwise (CCW) rotation. Verify the rotation direction of your existing installation before ordering -- the blower wheel must turn in the correct direction for the scroll housing to pressurize the outlet. On most motors in this family, rotation is set by the wiring configuration at the time of installation.
