I got an old AC fan from my neighbor when their AC was replaced. He says it's
called a squirrel cage blower. It worked when they took it out, they just got
a new one. I want to use this old one in my garage on hot days. Where can I
find a way to wire it up and have lo-med-hi speeds and everything?
Many times there is a wiring diagram on the side of the motor.
Find a friend that has an ammeter so you can check the amps, many times when
you hook up a squirrel cage fan in free air that was designed to run a
static pressure, you will need to block off some air to keep from
overloading the motor.
You dont....really. In order to do what you want, it would cost more in
parts than it would to go to Lowes and buy an air circulator...
Hell..I have about 30 of the AC blowers out back, and even I dont make them
FYI: I have a belt driven, squirel cage blower, from a heating system of
some kind, bolted to a stand in my garage. It blows a hell of a lot of air. At
least 4 times as much as a box fan. Makes a great garage fan.
Good. Belt driven units are not as prone to go boom as a direct drive model.
But still, my circulator that I got blows a hell of a lot of air, and I dont
need to worry about it doing to me, what I get to fix all day anyway...
I am not talking about a POS box fan...but a unit designed to move about 3X
as much air as a 5 ton blower will....
They push an enormous amount of air if blowing through, for example,
something like a wall, window frame or ducting. 1000 CFM or more...
One issue is that they tend to need 1/4 or 1/3 HP motors. That's a lot
Not cost effective if the blower unit doesn't already include the motor.
They certainly can. I built one. It's a squirrel cage blower on a 1/2HP
motor, but not a furnace/AC type. [It's out of a computer and much
smaller. Noisy tho. Needs a muffler.]

It's not just anyone who gets a Starship Cruiser class named after them.

All Blowers that come out of gas furnaces are 120 volt and all Blowers that come out
of Air handlers, Electric heat , and Gas
Package units or All Electric Package units are all 220 volt motors.
You will just have to find a gas / Propane furnace blower Assembley to be 120 volts.

I've got a larger box fan sitting on a pedastal I made for it in the window
of my garage. when I'm doing dusty/smokey work, I run it so it "sucks" the
air out of the garage. on hot days I turn it around and it "blows" into the
garage for a breeze. more than enough power to keep a 21x28 garage cool
i got three of them... they cost me $5.00 each... the guy that rigged
them up just took an old lamp cord and attached one wire to one speed
and the other wire to common on the fan..... they all work great... who
is gonna worry about fan speed when you are soaking wet with sweat in
the middle of the summer.. thats all i use them for.. one thing:
if you gonna stand out in the sun working on a car with the fan on you
for the heat.. (like i did)... when you are finished you gonna feel real
burned... the fan kept me cool but the sun was still burning my skin..
when finished i was burning up ..... similar to the wind from the
