110 v ceiling fan replacement

[abrodsky]

Restoring a 1958 Flying Cloud and need to replace the ceiling fan, which is wired for 110. Is it possible to find a replacement 110 v vent, or do I need to rewire for 120?

They are the same. The voltage coming from the utility is 120 volts but is commonly called 110. Most AC motors will operate between 100 and 130 volts without a problem.

Now that said are you sure the fan motor is 120 volts AC or 12 volts DC. All modern RV vent fans are 12 DC. I can't say that 120 AC was never used but I have never run across one.

thank you for the clarification. Obviously, I'm starting from scratch on this project with nothing but knowledge to gain! I am looking at a Fan-tastic vent replacement, which is 12volt, as a replacement for a 110 ceiling fan/vent. Would like to find a 110 v fan/vent so that the wiring does not have to be redone, but....is this possible? What is involved in rewiring if not?

The fantastic vents use 3 amps, max. One possibility would be to place a small 120 to 12v converter near the vent. See for example:

Amazon.com: Wagan 5 Amp AC to 12V DC Power Adapter: Automotive

There are many other similar products of various shapes, sizes, prices, and (presumably) quality.

Pulling new wire through the ceiling of an Airstream is almost out of the question because of the metal ribs and the fact that the wires go through those ribs.

Airstream generally runs the factory wiring down the center of the ceiling making it even harder to steal the old wire. The fan is probably the first thing on the circuit and thus you could not steal the 110 wire to the fan without losing the balance of that circuit.

One option is to find a small surface mounted wire channel and run the 12 volt to the fan.
