Direct HVAC Replacement Motor
The Dayton 4HZ67 is a permanent split capacitor motor rated at 1/3 hp and 1650 RPM for 115 V AC single-phase supply. It fits 48Y frame stud mounts in any angle and serves as a direct replacement for manufacturer numbers 4HZ23, 4HZ41 and 4HZ43. Buyers needing a different horsepower, voltage or frame size should look elsewhere.
Thermal Protection and Continuous Duty
Auto thermal protection and Class B insulation allow continuous operation up to a 40 °C ambient temperature with a 1.0 service factor. The open air-over enclosure relies on the driven fan or blower for cooling, so noise and surface temperature depend on that airflow. Full-load current is 4.0 A at 60 Hz.
Clockwise and Counter-Clockwise Rotation
The shaft rotates CW or CCW, letting the installer match the original fan direction without rewiring. This single-speed design suits constant-speed fan and blower duties in HVAC equipment. Verify that the application requires exactly 1650 RPM and 115 V before purchase.

Questions about this item
How is the 48Y frame motor mounted to the equipment?
The motor uses a stud mounting type and can be installed in any angle, so align the studs with the equipment bracket and secure with nuts.
What maintenance does the permanent split capacitor design require over time?
The auto thermal protection resets itself after overheating, but the capacitor should be checked periodically and replaced if the motor struggles to start.
At what ambient temperature does the 4.0 A full-load current reach its limit?
The motor is rated for a maximum ambient temperature of 40 degrees C; sustained operation above that will trip the thermal protection.
