Direct-Drive Blower Motor for HVAC Systems
The Dayton 3LU80 is a 1/3 hp single-phase motor built for direct-drive blower applications in heating and cooling equipment. Its permanent split capacitor design provides reliable starting torque and continuous-duty operation. Four selectable speeds let installers match airflow to specific system requirements. The motor suits technicians replacing OEM units in residential or light-commercial air handlers.
Electrical and Environmental Operating Limits
Rated for 208-230 V AC at 60 Hz, the motor draws 2.9 to 3.14 full-load amps and carries a 1.0 service factor. Automatic thermal protection guards against overheating, while Class B insulation supports a maximum ambient temperature of 40 °C. The open air-over enclosure requires airflow from the blower wheel for proper cooling, so it must not be run in still air or sealed compartments.
Installation Checks Before Ordering
Verify that the 48YZ frame and 5 13/16 in. shaft length match the original motor dimensions and coupling method. Confirm the resilient-ring stud mounting pattern aligns with your blower housing brackets. Ensure the supply voltage falls within the 208-230 V range and that the blower wheel will provide the airflow the open enclosure needs for motor cooling.

Questions about this item
Should I pick the 208V or the 230V supply for this motor?
The motor runs on any supply between 208 and 230 volts AC, so use whichever voltage your building provides.
What does the 1/3 hp rating deliver in daily operation?
It provides continuous-duty torque for direct-drive blower wheels at 1075 RPM with a 1.0 service factor.
How does the 48YZ frame limit mounting options?
The 48YZ frame uses resilient-ring studs and fits all-angle mounting, so orientation is unrestricted.
