Dayton UL14-3050 Actuator Closed Base

The Dayton UL14-3050 is a closed-base actuator designed for use as a fan accessory. It serves as a direct replacement component for compatible fan assemblies. The unit is supplied in new condition.

Compatible with listed Grainger part numbers

This actuator fits systems using Grainger part numbers including 2FTU9, 2FTV7, 2FTW8, 2FTX4, 2FTX5, 3C242, 3C243, 3HHL4 through 3HHL9, 3HHN1 through 3HHN3, 3HHR5, 3TZ50, 4C224, 4C225, 4C228, 4HX64 through 4HX71, 5NKN7 through 5NKN9, and 6WRK7 through 6WRK9.

Closed-base type

The defining specification is the closed-base construction, which determines how the actuator mounts and operates within the fan assembly. Verify that your hardware requires a closed-base type before ordering.

Questions about this item

How is the Dayton UL14-3050 closed-base actuator installed, and what step is often missed?

Mount the closed base securely, then connect the actuator to the compatible Grainger part number listed for your fan model; the step often missed is confirming the exact Grainger part match before wiring.

What maintenance or replacement will the Dayton UL14-3050 actuator need over time?

The closed-base actuator itself is a sealed unit; plan to replace the entire actuator if the motor or drive mechanism wears out, as internal components are not serviceable.

What limit appears first on the Dayton UL14-3050 under sustained operation?

The closed-base design limits heat dissipation, so thermal protection will trip before mechanical wear becomes an issue during continuous duty cycles.
