Does anyone know off the top of their head how much they are and how much power they take?
Ive got a "little" DC 12v motor but it takes about 400 amps to startup.. :-/

i was looking at that eram thing. First, $250 is way too much for that. I bet it would work better if they make the fan blades longer, (this would increase the air it would move, right?)

Yess but it would also need a larger tube to be inside, and increase resistance, thus the mush more power is needed to spin them.

i was thinking about hooking it up to a dryer tube or something, then putting it out of the way, so that you could have the blades as big as you want. it would look like this:
_______
----/ \ | / \-----
-- () --
----\__/__|_\__/-----

Thats the fan in the middle.

the bigger the blade increases the power needed to spin them at the same speed. It could be too much for the motor

disregard that drawing, the post screwed it all up.

Yeah, you might blow the motor, but will it move more air?

Probably not. Because the motors are most likely maxed out on power. So to move more air it would have to spin the bigger set of blades and extra force of air (assuming there are just as many and they are the same pitch) at the same speed as the smaller ones. but the motor will just usually slow down and heat up to make up for the work of spinning more mass.

my thought was to put it outside your filter so that it doesnt cause turbulence. I would have it run all the time and just blow at the filter, like simulated Ram Air no matter what the speed. Advantage would be that you could have close to ambient air temps no matter what. Put it on the dryer tube end that is closest to the filter and it will negate all those turns, right?

Then you will need the power to keep that thing running thats a ton of it

if we use it for the application that I described, I bet we could get away with a smaller motor and fan tho, so the power draw wouldnt be as much.
