Hi All

Those with separately driven fans on their spindles - do those fans draw the air up from the bottom, or do they push air down from the top?

If pushing down, any concerns with deflecting the air exhaust to avoid throwing up dust?

On the Colombo the fan blows down from the top. The flow is less than you would get from a routers exhaust and really dosn't blow dust around much.

Thanks Eric, that proves that the Colombo doesn't suck.

I mounted a Pabst fan (http://www.talkshopbot.com/forum/messages/7/10057.html#POST29444) on my Fimec spindle and it just seemed upside down with the label underneath, but obviously the direction is correct to avoid sucking in dust.
