Not sure I understand, he has a blower that is pushing a large
impeller... something that a 2hp motor would be required for. His is 2/3
Both his DC and this blower are on, and he is overcoming the more
powerful DC... which he should not be able to.
So it is more powerful.
His home made impeller is certainly more efficient that the 4 or 5 blade
one in the larger unit so it probably spins with less effort.
Having said that, the smaller unit simply relieved the pressure inside
the filter bag, naturally the bag would collapse. Had the smaller one
really out performed the big one I suspect that the bag would have
totally collapsed immediately rather than gradually float down.
Since the bag did not actually flatten the larger blower still out
performed the smaller one. And depending on the layer of dust in the
upper bag, the less the restriction, the more the smaller unit would
appear to be out performing the larger one.
What a cool project to work on.
Yes, he is quite a patient model builder....
I envy his carefulness......
I was wondering what it would be like to either cast in aluminum, or build
with sheet metal......

I do not understand how a 2/3 hp motor can out perform a 2 or 3hp motor
on a big dust collector.
