I just picked up a Kooltronic model KBB35-102 centrifugal blower. Te outlet on
it is 2-1/2" square. There's no CFM rating on it, but it produces enough air
for 10 3-500Z's, I think. Since I have just two, I want to reduce the speed and
noise a bit. I tried it on a variac, and it seemed to do a nice job at 90v.
The motor is rated 1/35 hp, 1a at 115v. It appears to be an induction motor. My
question is, is it OK to reduce the speed with a series resistor, or could this
damage the motor?
