All I have ever used is a shop vac (12 gallon, 4.5 amp, 1 hp peak). I
just got the Delta 50-850 dust collector, put it together, attached 4
ft of 4" hose and a short section of 2 1/2 hose with an adaptor to go
from the 4" to 2 1/2. The shop vac has noticeably more suction. Please
don't laugh if I have made a ridiculous statement, I am totally new to
this. Need some help here, advice etc to determine if the new machine
is working properly. Another thing I have noticed is that the filter
bag never fully inflates, unless there is no hose attached to the
inlets and they are both open (with no covers on them). I guess I was
expecting something different....
Thanks In Advance,

With tools that require a 2 1/2" or smaller hose, you're probably
better off using the vac. Also, you can put a high quality HEPA
filter or drywall bag in most vacuums, making them better for sanders
and other tools that generate fine dust.
Save the DC for bigger tools that make bigger chips.
I too noticed a similar phenomena when I switched from a shop vac to a
cyclone. I would suggest that David install a wye and a blast gate (not
necessarily connected to anything) in the line. When he runs a router or
sander with a small opening he opens the blast gate a bit to allow a bit
more air to move through the system. There will still be more than enough
air movement in the small line to clear the dust. Cheers, JG

Sounds like the motor is not getting fully up to speed. I had that problem
with a 2hp ShopFox dust collector about 2 years ago...they sent me a new
motor and now it fires up REAL quick and draws hard enough that it catches
about 75% of the chips/dust off a contractors TS that just has a flange
fitting under the frame...all while still pulling all the chips from the
planer that's going at the same time. All this is thru 4" heating pipe and
flex hose and a cyclone separator.
Check out the motor soon!
You are choking the machine to death. It was designed to
move "large" volumes of dust/chips. It is "NOT" a vacum
Hook it up to a 15" planer or a table saw with 4" hose and
you will see what it's capable of doing.
My filter bag is tight as a drum when the machine has
a single hose attached to my DC-380 planer. I have never
tried to use both outlets at one time.
This DC has rated well in every single test of DC's I have
You didn't mention what you were hooking up to ????
