Your options are :
a) Get a 110/220V transformer (not cheap)
b) Run a 220V line for this purpose. Your house will likely have 220V
capability. The normal 110V feed is two separate phase 110V line. You get
220V by having a breaker join both lines.
c) Get rid of the 220V units and replace with 110V units.

If you run the present fans on 110V they will burn out. The motor is
designed for a certain wattage. Watts = Amps x Volts. If the Voltage is
half design, the Amps will be twice design and normally burns out the motor,
typically very fast and "energetic".

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
