Furnace fan

[Reg1952]

I have a fan out of an old oil furnace and I want to use it. It has 3 wires coming off the fan motor which is mounted in side the squirrel cage. A white,black and red. Anyone know which one is power,common etc. Thanks

look like a 2 speed fan black is high speed red low speed white common . so if you wire black to black white to white & cap the red you have high speed . black to red white to white cap black should low speed

The high speed setting,makes a good blower to cool a motorcycle while your adjusting the carbs,you'll need a base to mount the fan on,and a restrictor to limit the intake air,otherwise the motor will overload.

Or you can limit the outlet like the duct work does....
