The Dayton 1TDP4 is a direct-replacement squirrel cage blower motor designed to swap in where the original Dayton 2C067 has worn out or failed. At 71 CFM and 1580 RPM on a standard 115V/60 Hz circuit, it restores proper airflow to HVAC, ventilation, and climate-control systems without rewiring or fabrication. Ball bearings and Class B insulation mean this motor is built for continuous-duty use, not just occasional cycles.
If your existing Dayton 2C067 blower motor has seized, overheated, or lost output, the 1TDP4 is the correct replacement. The dimensions, shaft size, rotation direction, and electrical specs match the original, so installation is a straightforward swap on compatible equipment. No adapter plates, no rewiring -- just disconnect, remove, install, and reconnect.
Also sold and catalogued as NBK Parts number 20496, so you may find it cross-referenced under either designation when sourcing through HVAC or parts distributors.
Precision ball bearings on both ends of the shaft support longer service life and quieter operation compared to sleeve-bearing alternatives, especially in continuous-duty or high-temperature environments.
Built-in thermal overload protection shuts the motor down if it exceeds safe operating temperature, then resets automatically -- protecting both the motor and downstream equipment.
Class B motor insulation is rated for continuous operation up to 130 deg C (266 deg F) winding temperature, well above what typical HVAC blower duty demands.
Rated for both 50 Hz and 60 Hz supply frequency, making this motor suitable for North American installations and compatible with most RV shore-power and generator sources.
The 1TDP4 runs clockwise rotation when viewed from the inlet side. This matches the original 2C067 orientation. Verify your existing unit's rotation direction before ordering -- installing a motor with the wrong rotation reverses airflow through the blower housing and significantly reduces system performance.
This blower motor is used in a range of forced-air applications where compact size and moderate airflow are needed:
The 8 mm shaft diameter is standard for the 2C067 blower wheel. If you are reusing the existing blower wheel, verify the bore matches 8 mm before reassembly. Wheel diameter on the original application is 5-1/4 inches -- confirm clearance in your housing. The motor draws only 0.50A at 115V, so no dedicated high-amperage circuit is required; a standard 15A branch circuit is more than adequate.
