Hi,

I'm getting ready to make one of these, and was wondering which way
to orient the fan. 

Should the exhaust go straight up, or out horizontally?
Low to the floor, mid height, or attach to ceiling (saves floor space)?
Which way would be best to filter the most air quickly? 
Or does it not matter much one way or the other?

Interested to hear from people who have experience with this kind of set up.

Chris

I just finished mine, so haven't much experience with it yet.  1/3hp furnace 
blower, 5 pleated furnace filters (1-20x25, 2-16x20, 2-16x25 from WalMart), 
mounted at the center of the ceiling, blowing up into the space between 2 
joists.  Covered the joists with 1/8 masonite to make ducts to carry the 
filtered air to the ends of the shop (30' long x 19' wide).  Want the clean 
air flowing down the walls & along the floor to the center of the room, & up 
to the filter, bringing the dust with it.
The airflow pattern isn't even.  I want to add ducts at the room ends to carry 
the air to the corners.

Like I said, not much experience with it, but the filters *are* getting dirty.
