I just finished installing a new Oneida Dust Gorilla dust collector that is
really overkill for a two car garage shop. The duct work I used was HVAC
sheet metal with hand cut 4" Y's off of the main 7" line. The 4" runs are
flexible aluminum dryer tubing running to the machines in the shop. When I
started the system it has so loud a whistle that I can't stay in the shop
with it running. Opening all of the blast gates helps some, but it is still
intolerable.

I have duct taped all of the joints. What do you-all suggest as a next step
to silencing this monster.

The noise is mostly emitted throught the exhaust/filter. The type of
ductwork is not really important concerning noise.
Moving the collector to another area would be the ideal solution, but if
sounds like it might not work for you.
Think about building a "sound" wall around it. Don't have a better
solution, except maybe piping the exhaust out to another location.
I have an Oneida as well, and I plan to move it out of the shop when I build
on an addition. But it isn't for me a sound problem as much as space.
However, I am not in a residential situation.
I would suggest that you call the salesman who you dealt with at Oneida and
bounce the problem off of them.

Hope it works out for ya, woodstuff

Me too. I'll be watching to see if Paul finds a solution. My Oneida system
sounds like a C5 taking off. Ear protection is a must.

Mine isn't really that loud, to my perception, since it is in front of the
rear door of a larger structure, but I can imagine what it might sound like
in the corner of a garage! It really helps me to have had a hearing loss
also!

(The ear doctor told me I had "Carpenter's Hearing Loss".. I asked him if he
was serious, and he said he was just kidding. I just have been around too
much noise most of my career. We didn't have hearing protection, or
anything else for safety when I was younger.)

My hearing loss began in 1951, at age 18, in Korea. Not bad enough, I went
to work for the Fire Department and listened to sirens for 33 years.
Now the firefighters have headphones. Too late for me. So I try to save
whatever hearing I have left.

Max (huh?)

Wow! Seems that I am officially the youngest one in this newsgroup! Wasn't
born until 1948...

Did yo check to see if Oneida could be of any help? Just a thought.
Otherwise, you are probably stuck with good hearing protection or moving the
unit to an outside shed and piping the main line through the wall. I moved
my little-buy-noisy, HF unit to the other garage bay which is separated from
the shop by a wall. I can barely tell that it's on except for the rushing
of air type sound.

Does it whistle when all the dryer hoses are removed? Most folks use
the vacuum system hose which is wire reinforced and smooth on the
inside. Not much whistle generating from smooth hose. I do not think I
heard any real whistles when I have been in 4 different shops with
systems that moved from a few thousand cfm to a lot. The all had
smooth mains and vacuum hoses for the last few feet. Smooth mains was
either spiral metal ductwork or pvc. The vacuum itself might be noisy
but that is solved by have the exhaust outside or in an acoustically
dampened room.

All those hand cut y's can make noise. If you smooth them down on the
inside and use hvac mastic they might be quieter. Mastic also does a
better job of controlling leaks in tricky areas. Smooth is quiet,
chopped up is noisy. That is one reason newer cars are quieter. They
do not have the noisy rain channels the cars of the 1960's had.
Turbulence is noise.

Duct sealer is a thick muddy paste used for HVAC work. It will seal a
vac system much better than Duct tape.
