The old motor was outdated and I was worried about getting the proper motor but this part number crossed over to that motor and it fit and works great.

Replaced a sleeve bearing blower with this ball bearing unit. This one runs much cooler and uses about 1/2 the power of my old one.

Works Well, Quiet

Saturday, November 06, 2010

I bought this for a home built fireplace heat exchanger. It is pretty quiet and has pretty much the perfect CFM. It would have been better if it came with a cord and switch otherwise, it is pretty much just what I needed. This one was not made for variable speed but then again, the CFM is pretty much perfect for my application. You can adjust the airflow by adjusting the intake cover.

Quiet. Correct airflow

Switch, Cord, Variable speed
