is a 4" duct large enough for a spray booth? I guess it depends on the blower size,
but the booth I had set up in Miss. (it's in storage just now, unfortunately) had a
10" circular fan venting directly out into an attic storage space with no duct at all.
The fan was a surplus unit, I probably would have gotten something a little smaller
if I had to pay for it, but too small and too long an exhaust duct might cut down
your airflow considerably.
Is the 4" duct what other folks are using?
