Any chances of posting links? I'd like to learn about the differences.
I'm
guessing that forward inclined means the blades tip inwards in the direction of rotation? And so pull from the center and expel to the outside? (btw, the forum editor wants to change o-u-t-w-a-r-d-s to ****wards - is this some kind of rude language I don't know about?)
Backwards inclined means the reverse of this? Blades tipped to the outside? Flow towards the center? This would mean that, in spite of looking like centrifugal pumps, squirrel cage fans are actually using aerodynamic lift?
Thanks!
