I'm adding a duct run to my furnace, and I've seen takeoffs with "scoops"
which are apparently intended to help direct air into the new run. Is there
a particular reason why you would or would not want to use one of these
scoops? Thanks in advance...

The only advantage I could see to adding a take-off with a scoop is if
you're having a problem in one particular room that comes off a trunk line
with other take-offs. The scoop will catch more air for that particular
take-off but you have to always remember, you can't put more air in one
place without taking it away from somewhere else.

The "scoop" he is refering to *could* be a damper

Never really thought of it that way, but you are right. I guess the
definition of "scoop" is the problem here. Well, by "scoop" I mean an
actual curved piece of metal attached to the take-off that sticks out into
the flow of air kinda like a hand scooping water.

If you order a system with a damper, and then remove it, do
you still need a drier ?

I mean scoop... I know the difference between scoop and damper. It's a
curved piece of metal.

I ordered my takeoff with a scoop. If I don't need it, I'll cut it off.

I have not been very successful with a scoop. Most of the time they can work
against you. If you scoop too much air you probably will not be able to
balance it. We had to remove scoops, extractors. I would recommend using a
balance damper in the branch lines & that's provided you can get to them.
Usually if not enough air or improper balance of air at the plenum may be
how it's designed, size, connections, & you need a buffer of hopefully 12".
Check your manual "D" & that may be helpful.
