Default One big ass fan!

Hey guys! I got one hell of a big fan from work the other day. Only problem is that it takes 24Volts and .55AMPS. How do I get this thing powered? Do I need a converter or something? I am going to be building a new system soon and I would like to put this thing on with a variable speed switch.

Ooo it's looks excatly same company makes a fan on my old Espon MX-100 wide carriage commerical printer, it's runs off the 24 VDC and hear little noisy like a "vroooom". I had to change the printer settings on the DIP switches hehe!

I dunno, and you can search on google to find the convertor from 24 VDC to lower VDC..

I wonder how much CFM this thing produces. All I know is that it's big and big is better.

Yes but the question is how do I convert the voltage.

ok, get a transformator that puts out 24 volts ( see, if ya got 110 volts from the wall socket, you would need a (i don'T know the correct names foir the stuff in english, if ya don't understand or know a better woird, pls tell me) ya need a soft iron core with to wires warapped around ervery side of the O-formed core. on one side (the wall socket side) ya need the wire 4.5 as much times wrapped around the thing than on the other side. if ya hook the cable from the socket side to the socket, the current will flow through the wires and produce a pulsing magnetic field in the soft iron core. this field produces current in the other wire wrapped around the other side. this is called induction. and since ya got 4.5 as much wrappings on the socket side, it will only put out mains current divided through 4.5 on the secondary side. so ya got 110/4.5 and ya get nice 24.4 volts on the secondary side. but it is AC and so unsuitable for the small DC motor that probably sits in the fan, so ya gotta get a (dunno the name, but it converts AC to DC using 4 diodes, in german it is called brueckengleichrichter) AC/DC converter and voila, ya can hook up ya fan. you could also get some voltage regulator from radio shack. i will have a look around for ya and get some way to get the fan running. i owe ya that much, this is one chance to do something for ya that helps. :-*
