1/2 HP PSC Blower Motor
The Dayton 4YU28 is a single-phase permanent split capacitor motor rated at 1/2 horsepower with a nameplate speed of 1725 RPM. It operates on 115/230V AC at 60 Hz and fits a 48Z frame for direct-drive blower applications. Continuous duty cycle and Class B insulation support reliable HVAC operation.
Who This Suits and Who Should Look Elsewhere
Installers replacing 16D536, 16D537, 4YC69, 4YC71, 5DVP8 or 5DVP9 units will find a direct match with auto thermal protection and CW/CCW rotation. Buyers needing 200V or 208V compatibility should select a different motor. Builders requiring multi-speed control or enclosed housing must choose another model.
48Z Frame 115/230V Voltage
The 48Z frame and dual-voltage 115/230V design determine fit and electrical compatibility in existing equipment. Full-load current draws 6.0 amps at 115V and 3.0 amps at 230V with a 1.0 service factor. Maximum ambient temperature is rated at 40 degrees C for continuous service.

Questions about this item
How do I choose between the 115 V and 230 V wiring options for this 1/2 HP motor?
The motor is dual-voltage rated at 115/230 V AC with full-load currents of 6.0 A at 115 V and 3.0 A at 230 V; select the voltage that matches your supply and wire accordingly.
What does the 1725 RPM rating mean when the blower is running under load?
The nameplate speed is 1,725 RPM at 60 Hz; as a permanent-split-capacitor design with a 1.0 service factor it will run close to this speed continuously at rated load.
What does the 48Z frame designation tell me about mounting and shaft compatibility?
The 48Z frame defines the mounting footprint and shaft dimensions for direct-drive blower replacement; it matches the listed cross-reference models 16D536, 16D537, 4YC69, 4YC71, 5DVP8 and 5DVP9.
