15? Geez, your shop must be in a cave! I have about 2200 shop and have
one overhead extractor exhaust in my work area that moves over 800 cfm.

These Honeywell units say they change the air in an 13'x13' room 6
times and hour. So I need about 15 units. I think these are better
than and overhead unit as they are right on the benches where the dust
and fumes are created. Not pulling all the dust through out the shop
to the ceiling unit.
