What is the effect on the cfm when you downsize a residential blower belt.
Does it increase or decrease it?
At 2:00 AM, I had to use a 41 inch belt to replace a 42.
The amp draw was right on, and the tension bar was fully extended with the
42", which leads me to beleive it was originally a 41.
I couldn't envision WHY the pulleys would react differently to varying
lengths, but I wasn't sure.
I thought I remembered something from long ago about it altering rpm in
some way, but couldn't figure how it would.
OK, NOW I think it's safe to say that I know everything.... :-)
Did you use a night time belt with flourescent coating or just a plain
daytime rubber belt?
At 2:00 AM you should have used the night time flourescent coated
Hopefully you used the pulley expander and blower wheel strecher to
properly install it?
Dont forget to coat the vanes of the wheel with whale sperm. This will
produce better air flow.
Sorry Bob, I couldnt resist. There will be no change in blower cfm
unless the old belt was very stretched and loose and the new belt was
put on tight. Then you would get a slight increase in blower speed/cfm
due to the slippage of the old one.
Those damn belted motors are tricky!
uhuh is the fan blowing the right way bobby?
