  • 1/2 hp permanent-split-capacitor motor delivers continuous HVAC airflow
  • Three-speed operation at 625 RPM matches variable ventilation needs
  • Dual-voltage 208-230 V AC design fits common commercial power supplies
  • Auto thermal protection and Class B insulation guard against overheating
  • All-angle stud mounting with 6 in shaft simplifies replacement installation

HVAC Blower Motor 1/2 hp

The Dayton 3LU82 is a direct-drive blower motor rated at 1/2 hp for HVAC control applications. It operates on single-phase 208-230V AC power at 60 Hz and fits a 48YZ frame. The motor is designed for continuous duty in air-over environments.

Three-Speed Permanent Split Capacitor

This motor uses a permanent split capacitor design with three selectable speeds and a nameplate rating of 625 RPM. It delivers 4.0-4.5 A full-load current and provides reversible CW/CCW rotation. Auto thermal protection and Class B insulation protect the windings during operation.

Thermal Performance and Power Draw

The motor carries a 1.0 service factor and is rated for a maximum ambient temperature of 40 degrees C. Auto thermal protection interrupts power if internal temperatures exceed safe limits. Continuous duty cycle and open air-over enclosure allow steady heat dissipation during normal HVAC use.

Questions about this item

What does the 1/2 hp rating mean for airflow in my HVAC unit?

The motor delivers half a horsepower at 625 RPM, providing steady airflow for residential or light-commercial air handlers.

How does the 208-230 V single-phase supply affect installation?

It runs on standard 208-230 V AC single-phase power at 60 Hz, drawing 4.0-4.5 A at full load, so a dedicated circuit is typical.

Will the 1/2 inch shaft and stud mounting fit my existing blower housing?

The 6-inch long, 1/2-inch diameter shaft and 48YZ frame stud mount are designed for direct-drive blower wheels in compatible housings.
