I had worked with a IVP builder in the Denver area prior to getting my kit
and noted that he had installed a dust collector in his garage attic
(finished
ceiling).  He had a lower HP model and ran it when ever he was working.
My garage is underground (roof and all sides except the one exposed with
doors) so ventilation presented a little greater challenge.  I initially
installed
 just 1 exhaust fan at my epoxy work bench, using the large windows on my
exposed wall for inlet air to the workshop.  Months into the project, I
developed
epoxy sensitivity and did some aggressive changes to the ventilation.  I now
have a "forced" fresh air intake (which can be heated during our 6-8 month
heating season) and both fans are on a 2 hour timer.  When I finish lay-ups
in
my space suit at 1 AM, I can ventilate for a controlled time with a
controlled
temp and still be able to go to bed when done.
   Due to the epoxy sensitivity, I also at that time installed a dust
collector
from one of the wood working tool mail order houses.  I may have over-killed
the issue, but I purchased a 2 HP model with 4" piping on the ceiling &
a 15' rubber drop flexible hose.  The collector is mounted outside in a
facade
(attic like protection) which is well ventilated and on the opposite side of
the
garage as my fresh air intake. I now use the collector for not only the
obvious
use of dust collection, but also as another ventilation option that can be
placed
directly to an area with epoxy curing.  I built a small stand with a pivot
arm that
the hose is supported on, and I can adjust this from floor level to about
60".
Whenever sanding, I move the hose and stand to close by and never deal with
dust.  The only caution is tools and parts, 2 HP will remove them for you
and
deposit them nicely in your remotely located collector.
   Tom Murray, friend and Legacy builder just down the road, installed a 1
HP
dust collector in his shop with multiple drops on the ceiling & shut-off
gates
so he places his drop hose in the area he is working and can reach any area
of his shop by just moving the drop hose. The advantage of the 1 HP in my
opinion would be you could run it steady without to much cost.  The 2 HP
will
pull harder and farther and serves me well due to the multiple use.  Tom & I
have also noted the 2 HP could be used to remove unwanted or non-working
guests from the workshop.
