Once you try one of these you'll never use a box fan again.
BEST ELECTRICAL TAPES EVER!
Scotch super 88: amzn.to/2qP1QJ7
The Super 33+: is just as good, just slightly thinner for more flexibility: amzn.to/2rKnrjW
How to wire a furnace squirrel cage fan:
White: common to one side of the plug
Speeds: (pick one for other side of your plug)
BLACK: HIGH
YELLOW: MEDIUM HIGH
BLUE: MEDIUM (medium low if Yellow is present)
RED: LOW
GREEN: GROUND(hook it anywhere on the metal body)
If it has a pair of BROWN or BROWN w/white stripe wires, these connect to each side of the capacitor that should be present. If you don't have the capacitor the decal on the side of the motor will say what size you need and they are very cheap.
These fans are designed to run with constant restriction. So you need to recreate this when used out in the open by blocking roughly 25% of the air intake or output. If you don't restrict the airflow the motor will pull significantly higher amps than it is rated for and will overheat/burn out. If you want to be scientific you can look at the side of the motor and read the rated amps. Then with a load meter ( amzn.to/2rhGYLK ) hooked up, run it and block off the air flow until the amp draw drops to or close to the rated amps.
Centrifugal fans are amazing at moving a large quantity of air and the output can be ducted unlike axial.
