Dayton 3M769 Condenser Fan Motor 3/4 hp High Temperature 1075 RPM 208-230V AC 48YZ Frame 5 in Shaft

SKU CH-D2HZ-FHJNW

A permanent-split-capacitor condenser fan motor delivering 3/4 hp at 1075 RPM on 208-230V AC with a 5 in shaft

  • typeHigh Temperature
  • 3/4 hp motor powers demanding condenser fan applications
  • 1075 RPM nameplate speed delivers consistent airflow performance
  • 208-230V AC voltage suits standard commercial electrical supply
  • 48YZ frame with 5 in shaft fits compatible mounting configurations
  • Auto thermal protection and Class B insulation support continuous duty at 60°C ambient

Application fit

The Dayton 3M769 is a single-phase condenser fan motor rated at three-quarter horsepower for continuous duty in HVAC and refrigeration equipment. Its 48YZ frame and 5-inch shaft suit vertical shaft-up or shaft-down mounting on studs. The motor runs on 208-230 V AC at 60 Hz and offers two-speed operation for flexible airflow control.

Sustained-load behaviour

Rated for continuous duty with a 1.0 service factor, the motor delivers 1,075 RPM under full load while drawing 4.0 to 4.5 amps. Automatic thermal protection and Class B insulation guard against overheating during extended operation. The permanent split capacitor design provides stable torque without a separate starting capacitor.

Thermals, noise and power

Maximum ambient temperature is 60 degrees Celsius, and the totally enclosed air-over enclosure relies on the driven fan’s airflow for cooling. Power consumption stays within the 4.0 to 4.5 amp range at nameplate voltage. Reversible CW/CCW rotation allows installers to match the required airflow direction.

Questions about this item

How hot does the 48YZ frame motor run at 60°C ambient?

It is rated for continuous duty at a maximum ambient temperature of 60°C with Class B insulation and automatic thermal protection.

What capacitor and wiring are needed for the 208-230V supply?

The permanent split capacitor design requires a correctly rated run capacitor and a 208-230V single-phase 60 Hz supply drawing 4.0-4.5 A at full load.

Will the 5 in shaft and stud mount fit my existing condenser housing?

The motor has a 5 in shaft, 48YZ frame, stud mounting and vertical shaft-up or shaft-down orientation to match many condenser housings.
