Industrial Transformer Cooling Fan
The Dayton 13F055 is a guard-mount industrial cooling fan built for transformer applications. It moves 7000 cfm at 1725 RPM using a four-blade aluminum impeller. The unit operates on 208-230/460V three-phase power at 60 Hz and draws 1.4-1.5/0.8 amps. A 1/3 hp totally enclosed air-over motor with ball bearings drives the assembly.
Upgrade From Smaller Axial Units
This fan replaces lower-capacity axial models when transformer cooling demands exceed their airflow rating. The jump is justified when equipment runs continuously at high load and ambient temperatures approach 104 degrees F. Its 24-inch blade diameter and steel guard construction suit fixed industrial installations requiring sustained air movement.
High-Volume Airflow With Defined Limits
The 7000 cfm output comfortably handles heat rejection for standard transformer banks in ventilated enclosures. Headroom diminishes when static pressure rises above the guard-mount design point or when ambient conditions exceed the 104-degree rating. The 15-foot cord and 19 7/8-inch mounting eye O.C. define the installation envelope.

Questions about this item
What size guard opening is required to mount the 24 in blade diameter fan?
The guard mount needs a 19 7/8 in outside circumference opening, and the overall unit measures 27 in height by 27 in width by 13 5/16 in depth.
How do I wire the three-phase motor for 230 V or 460 V supply?
Connect the motor leads to a 208-230/460 V AC, 60 Hz three-phase supply; the motor draws 1.4-1.5 A at low voltage and 0.8 A at high voltage.
When should I expect to service the ball bearings on this 1/3 hp motor?
The totally enclosed air-over motor with Class B insulation uses sealed ball bearings; inspect them during routine HVAC maintenance and replace if noise or vibration develops.
