Like many of you I lack space. Most of my shop is in the 3rd bay of a
three-car garage and many tools are on wheels. I would like to install a
fairly robust dust collection system but floor space pretty much rules out
One thing I do have is ample overhead space - my garage has an 11' ceiling.
I have considered a shelf or rack of some type that would put the base of a
collector about 4-5 feet above the floor and nestled behind other floor
equipment. It might have to be emptied or serviced from a ladder.
Has anyone tried this? Are there any issues with debris lift to this
height? I have not made a selection but the machine would probably be a
1,200 - 1,500 CFM machine similar to the Grizzly G1029 or a similar Jet
machine. The Griz hast the collector inlet very close to the base. The
system would serve some or many of:
Stationary Belt/Disk Sander
Oscillating Spindle Sander
Floor sweep chute that would be installed beneath or near the lathe
Thanks in advance.
I'm using a Jet 1100 fed with overhead 4 inch lines from a
tablesaw, bandsaw, router table, drill press, jointer, planer and CMS. These all
climb over 10 feet to the main duct line. The only debris lift issue is with the
tablesaw, due to it's openness. So just where the tablesaw ductwork starts to
head up to the rafters, I've placed a Y fitting with a blast gate. Every now and
then, I'll pop it open, and whatever hasn't made the climb falls out. Sometimes
I'll hear a chunk of debris dancing in the vertical, and just opening the gate
sends it up and away to the separator. Good idea about the floor sweep near the
I think a less than commercial machine might have trouble lifting after
a long run. Not an expert though. The reason I responded was to ask if
you have considered placing it outside. A small shed next to a
location where you have a floor vent or cut a small pass through...
I'm thinking of doing just that... If you see any "holes" in the plan below,
The plan, when I can get the shop/garage clean enough, is to put the DC outside
in a 3 sided box with foam and fan... (it would be about 10' from a neighbors
Best idea we've had so far is to run pipe through a hollow core door that we
never open and have the cyclone (55 gal. drum) inside the shop for easy
emptying, and running pipes just above bench level in 2 directions, since the
door is in a corner....
I'm thinking of that height because it would be just about where the top of the
incoming hose is now on the cyclone... it's only a HF 2 hp DC, but it seems to
work very well for my needs/budget...

Don't think there would be too much of a collection issue w/ 4" mains
although I'd recommend blast gate at major vertical lift locations for
ease "just in case".
I'd think the servicing would develop into a real pita after a while,
however. I know the older I get the less easy (and especially more
aggravating) dealing w/ such (formerly simple and routine) chores
Don't suppose there's any chance of a small lean-to outside or stealing
from a corner of a utility room or some such to put the collector
outside the actual shop area? Could also have the advantage of taking
that noise out of the shop...
Duane... you've got me thinking now, as I'm about as lazy as I can get...
I use a fiber/cardboard 50 gal. drum for the cyclone.. if I had to elevate it, I
think I'd make some sort of port on the side of the barrel, near the bottom, to
dump the cyclone contents into a rolling hopper or something...

A cyclone is usually mounted up high, and the solids dropped into a
tube, connected to a large can. (Well, OK. There is one fellow, who
does really nice work, where the cyclone is outside, and the solids drop
directly onto the ground.) My neighbor has his Oneida at about 10', and
vents the exhaust out through a ceiling plate level vent, with no ill
effect, but there is still the barrel to deal with.
Without using a chip collector, I wouldn't want to have to muscle a full
bag down from a shelf with any degree of regularity. And using a
collector, I empty the bottom bag of mine about every 90 days, even
though it usually doesn't need it. It sorta hides in a corner behind
the wood rack, in spider territory.

Am I misreading this or did you mean that the collector has a bottom
openening that dumps the waste to the ground? I'm trying to figure out
how you would maintain a vacuum with that large (essentially no
enclosure) on the bottom of the cyclone. Gotta be a sealed hopper
affair that dumps to ground, right?
For sure. Those waste bags on the 1100-1500 CFM units are what? 30
gallon? Not something most of us want to wrestle with on a ladder -
even a short one<g>
A late response. I get shavings for my horses from a shop that has 2
big collectors. I have not looked up in a while but one had a 4 bladed
shaft with rubber flappers at the bottom of the cyclone. It would
rotate slowly. 2 of the flappers would always be making a seal. The
debri would fall out out of the flappers as they rotated past the
Ron - we're must be in the same neighborhood. I'm also in a tight 3rd bay
but have a very high ceiling. I've been thinking about the same thing.
I also can't plumb outside, since my 3rd bay is at the front of the
I already have a small DC plumbed for some short runs, with a 90* turn. I
think it would do OK elevated -- especially if I find a spot that would
shorten the run. I think a G1029Z or similar would be fine!
I'd *def* do a cyclone lid/chip collector like:
and leave this at floor level, or obtainable. This would be much less DC
bag emptying meaning you could put that in a less accessible place.
Yeah - The separate cyclone or chip collector can approach crossed my mind.
I have read about some large shop DC systems that have very large systems
mounted high - even on a second story. However the debris drops from the
cyclone, or similar system, to a first floor, or external hopper that
provides easy access. Seem like this can be scaled down.
The cyclone is better than I could have expected. If it's not getting 100%
(can't be of course) then it's real close. BTW, lifting the air stream to
8' ceiling height has not been any problem. All of my drops are from
Can't tell from the picture, but the outlet side of the cyclone can is
still connected to a 'normal' DC inside your shop, right? So the exhaust
air is filtered and recycled back to the workspace.
My air duct is up high, too, but that's after the trash can cyclone...
