Does it blow the air the opposite direction or just not
work as well as it should?

I have a 3 phase dust collector. Opening it up to see the
impeller direction would be a hassle. I just wired in a
new remote switch. 3 phase motors reverse by switching
2 of 3 hot wires.

This is why I am asking.

Shouldn’t hurt anything. Just turn backwards.

wont work as well. it is a centrifugal blower so the air will still go in the center and be forced out to the outside and out the outlet. you should be able to look at the fan on the back end of the motor and determine direction without actually having to look at the impeller.

That did the trick. It was running backwards.

Lucky it wasn’t a TENV motor.

Have your say...
