Dayton 4K058BG Capacitor-Start Aeration Fan Motor 3/4 HP 115/230V AC

SKU CH-ZNPV-RMZSZ

Capacitor-start aeration fan motor delivering 3/4 hp at 450 rpm on 115/230V AC with auto thermal protection and continuous duty rating

  • 3/4 HP output drives demanding aeration tasks
  • 115/230 V dual-voltage fits common farm wiring
  • 450 RPM nameplate speed matches fan curves
  • Totally enclosed air-over design resists dust and moisture
  • Auto thermal protection prevents overheating damage

Industrial Aeration Motor

The Dayton 4K058BG is a capacitor-start farm duty motor rated at 3/4 hp for continuous aeration fan service. It operates on 115/230V AC single-phase power at 60 Hz with a nameplate speed of 3,450 RPM. The 56Z frame steel construction suits rigid-base mounting in agricultural or industrial ventilation systems. Buyers needing variable-speed control or three-phase power will not be served by this single-speed, single-phase design.

Wiring and Mounting Notes

Dual-voltage wiring allows connection to either 115V or 230V supplies; full-load current draws 11.0A at the lower voltage and 5.5A at the higher. The motor shaft rotates CW/CCW and the totally enclosed air-over enclosure protects windings in dusty environments. Automatic thermal protection resets after cooling. Installers must verify the capacitor is correctly matched and that the rigid base aligns with the driven equipment to avoid vibration.

Pre-Installation Checks

Confirm the supply voltage matches one of the two nameplate ratings and that the circuit can deliver the listed full-load amps. The 56Z frame dimensions and shaft geometry must match the existing fan hub or coupling. Ambient temperature at the installation site should not exceed 50°C. Class B insulation and a 1.0 service factor leave no margin for sustained overload, so the driven load must stay within the 3/4 hp rating.

Questions about this item

How can I verify the motor is running correctly after installation?

Check that the shaft turns freely in either direction, the motor reaches the 450 RPM nameplate speed, and current draw settles near 11.0 A at 115 V or 5.5 A at 230 V under load.

What components come in the box and what must I supply separately?

The motor itself is included; you will need to provide a compatible capacitor, mounting hardware for the 56Z rigid base, and wiring for the 115/230 V supply.

Which voltage setting should I choose for my 115 V or 230 V circuit?

The motor is dual-voltage; wire it for 115 V AC to draw 11.0 A full-load or for 230 V AC to draw 5.5 A full-load, matching your supply.
