Direct-drive blower motor for HVAC systems
The Dayton 3LU72 is a single-phase permanent split capacitor motor rated at 1/6 HP for direct-drive blower applications. It operates on 208-230 V AC at 60 Hz and carries a continuous duty cycle. The unit is supplied new and restricted from sale in certain states.
Four-speed operation with automatic thermal
The motor delivers four selectable speeds at a nameplate 1 075 RPM with full-load current between 1.13 and 1.2 A. Automatic thermal protection and Class B insulation support sustained running at up to 40 °C ambient. A service factor of 1.0 indicates rated continuous output without overload margin.
48YZ frame with ring-stud mounting for any angle
The 48YZ frame uses a ring-stud mount that allows installation in any orientation. Open air-over enclosure design requires airflow from the driven blower for cooling. The black satin zinc finish resists corrosion in typical HVAC environments. CW/CCW shaft rotation is configurable on site.

Questions about this item
How hot does the 48YZ frame motor run in a 40 degree ambient when it operates continuously?
The motor is rated for a maximum ambient temperature of 40 degrees Celsius and carries Class B insulation for continuous duty.
What voltage supply and capacitor does the 1/6 HP permanent split capacitor motor require?
It runs on 208-230 V AC single-phase at 60 Hz and needs an external run capacitor matched to the motor's permanent split capacitor design.
Can the CW/CCW reversible 1075 RPM motor replace an older 48-frame blower with the same shaft height?
The 48YZ frame has the same shaft height as standard 48-frame motors and the reversible rotation lets you match the original airflow direction.
