16-Inch Three-Phase Transformer Fan
The Dayton 13F056 is a 16-inch guard-mounted cooling fan built for transformer applications. It delivers 3100 cfm of airflow at 1140 rpm using a four-blade aluminum impeller. The unit operates on 208-230/460 V AC three-phase power at 60 Hz and draws 1.3-1.4 A at the lower voltage or 0.7 A at 460 V. A 1/4 hp totally enclosed air-over motor with ball bearings and Class B insulation drives the assembly.
Upgrade From Single-Phase Or Smaller Units
This fan replaces single-phase transformer fans when three-phase power is available and higher airflow is required. The jump is worth it when the existing installation can accommodate a 19-inch square footprint and the mounting eye centers measure 11 3/4 inches. The 15-foot cord allows flexible placement relative to the power source. Buyers needing a smaller blade diameter or a different voltage should select another model.
Verify Voltage Phase And Clearance First
Confirm the supply is three-phase 208-230 V or 460 V AC at 60 Hz before ordering. Ensure the mounting surface accepts a guard-mount fan with 19-inch height and width plus 13 5/16-inch depth. Check that the 11 3/4-inch mounting eye spacing matches the transformer enclosure. The motor frame is 48Y and the maximum ambient temperature rating is 104 degrees F.

Questions about this item
What is the mounting eye outer circumference of the Dayton 13F056 transformer fan?
The mounting eye outer circumference is 11 3/4 in, which determines the bolt-circle size needed for guard-mount installation on the transformer tank.
How do you wire the motor for 208-230 V versus 460 V three-phase power?
The dual-voltage 208-230/460 V motor requires the internal leads to be reconfigured — low voltage uses 1.3-1.4 A connections, high voltage uses 0.7 A connections — before applying three-phase 60 Hz power.
When should the ball bearings in this 1/4 hp motor be relubricated or replaced?
The totally enclosed air-over motor uses sealed ball bearings rated for continuous duty up to 104 °F ambient; inspect annually and replace if noise or vibration increases beyond normal 1140 RPM operation.
