Hi all, I need help/advice...
I just got an old furnace blower assembly with a 990 rpm 240 v motor. I
want to build an air filter unit.
The squirrel cage is 12" X 12" and I just hooked up a 1745rpm 115v motor.
The original motor was rated at 990rpm. Is the new motor going to give me
better result by spinning the squirrel cage virtually 2X faster? I was
wondering if I could get away with a unit having filters on three sides?
Is there any sites on the web that show IN Depth, CLOSE UP photos on how to
construct a unit?
thanks for any suggestions/help
We did the following for brazing fumes but much of the expertise these
companies supply will be applicable to your use. I don't have any
connection with any of these and, when we did this, the information was
Air Filtering Equipment
You can start as I did with a simple fan and a metal stovepipe. This
is very easy and cheap to install. The drawback is that it usually
sucks a lot of warm air out during cold weather.
Most states provide free consulting. If you are in British Columbia
then you can contact the Workers' Compensation Board at (604)

it's a 1/3 HP motor... I plugged it in, and it runs real smooth, but when
I put a paper towel close to the sides, well, let's just say that I wasn't
too impressed with the drawing power of the fan...
if any one can help, it's you guys/gals on this board!
