Look around for a 50-100W transformer built for overseas appliances. The
fans don't take much power.
Any transformer with a 120/240 primary can also be used, if big enough.
There are lots of these in industrial control systems. How good a scrounger
are you? to use the dual voltage primary, feed 120 into one end and the 120
tap. Take 240 from the same end and the 240V tap. Leave the secondary
open.

I have six electric fans that were salvaged from an old computer
equipment cabinet (not a PC, but data center size equipment). I'd like
to repurpose them for either a downdraft cabinet or air filtration
system. The label states that they are 230V. Is there any possibility
of running them on standard 110V house current?

Thanks
