    Default Dust Collection Questions

    Folks,
    I am looking for some comments on my plans for dust collection equipment. I have no experience with that, so most comments and opinions will be helpful.


    I recently invested in some ‘better’ (for me) tools: I got a Grizzly 14” band saw and a job site table saw. My shop is in the basement of our house, in the so-called John-Deere-room, so space is limited, thus the job site saw. There is a direct connection to our living space for dust to travel, so I am in the market for a dust collector and an air filtration system.

    Dust collector:
    Since I am also limited electricity wise (115V only, limited amps) besides the space limitations, I have been looking at smaller (1HP) and portable units. I am planning to attach only the tool that I use and move the thing around as needed.
    This is my current favorite: Grizzly G1163P 1HP, 537 CFM, 30 micron bag filter - with a 3micron replacement available. Or I put it outside, with the hose running through the cat door.
    (sorry about the big pictures)

    I prefer it over the G8027 (below, also 1 HP, 500CFM, similar microns) because the static pressure is much higher (7.2” v. 2.76”).

    I this the G1163P (the one at the top) a useful machine to use with a band or table saw, a stationary sander, etc?
    Does the difference in static pressure matter?

    Air Filtration:
    I hope that an air filter will keep the dust levels in the shop down in the long term and prevent most of the spread into the house. I am mostly concerned with fine dust. Plan is, to run this while I work, plus 4h afterwards, and another 4h the next morning (when I am at work). I am looking at this unit: G0738 (1/8 HP, up to 409 CFM, 1 micron)

    Any thoughts on something like this? Does this help?

    I appreciate any thoughts or experiences. Thanks!


    BTW: I am looking at Grizzly, since I am reasonably close to their MO showroom. And picking up stuff there is always a religious (or pornographic) experience

    I would go for more CFM vs more static pressure.
    The first setup has a bag that is a dirty bitch to empty. All of the dust and chips have to go out the 4" inlet hole.
    It begs for a cyclone garbage can lid,like so

    The second setup gives you the option to upgrade to a proper filter bag.

    Given the choice,I would put it outside and push the hose through the cat door.

    Hard to beat a Ridgid shop vac, a cyclone lid for a garbage can and a switch that turns the vac on when the tool is turned on.
    Cheaper than those big rigs, easy to move around the shop and very effective. Spend a couple bucks on fittings for each tool and youll be well served.

    Any of the ceiling mounted filters are fine. Go for ease of filter changes and variety of filters.

    Simpler is better, except when complicated looks really cool.

    If the concern is fine dust, I'd concentrate on the bandsaw and sanders.

    From the post above : Nov 2016
    **************************8

    Small unit:
    Dust Deputy by Oneida, =>> 50 Stars !!!!
    They make bigger versions of this particular inline extractor and much larger systems.

    http://www.oneida-air.com/category.asp?Id={CC6B6F2A-E3D7-4F18-A53C-B5C357DFE131}

    It has impressed so much we bought a second unit and recently vacuumed up the dust left from decades old loose fiberglass insulation that was on top of a 27' x 50' ceiling in a building we are gutting. I was dreading the residual dust and then ===>>> the filtering results of the 'Dust Deputy' were astounding. The little itty bitsy glass fibers in fact did get trapped and deposited by the cyclonic action and hardly any got past - Hooray !!
    If I were looking for a larger system after this units stellar performance Oneida-Air would the first place I would look.



    This is in fact our experience with the Dust Deputy
    This is the first lesson ye should learn: There is so much good in the worst of us, and so much bad in the best of us, it doesn't behoove any of us to speak evil of the rest of us.

    A couple of suggestions on top of the above advice.

    1. What dust collector you buy might oughta depend on the next machine you plan on acquiring. So far If it's a planer, then you really need the higher CFM and 4" hose of a dedicated collector vs. a shop vac. A big shop vac might keep up with a portable table saw that really can't capture all the dust because of the way they're built, but not with a planer.

    2. If floor space is at a premium in the basement, look at wall-mounted dust collectors or shop vacs. Mounting one high enough to put a trash can and cyclone lid underneath would put the footprint at about 24x24", half what my 220V unit takes up.

    3. Contractor saw dust collection: There are "diaper" systems of canvas with snaps that will create a chute under the saw, which would challenge a shop vac. If you regularly store the thing that isn't going to work either. I made a chute for my contractor saw with masonite that works fine but took a lot of fiddling, not worth it if your time is valuable.

    Cheers, Dan

    I will add one point here - a co-worker had/has a shop under the house - he found you need to pay close attention to the door sweep and seals around your access door to keep dust / sawdust from migrating to the living space. Also consider a mat to grab dust from shoes.

    Thanks everyone for the comments, much to consider and think about.

    One reason for getting a job site table saw was that I can easily move it outside and work on the concrete pad in front of my shop, which I usually do unless it is so cold that my fingers stick to the table (as is now), or the skeeters are too bad. The saw has a decent dust port at the blade that gets most of the chips, even when used with a small shop vac.

    Indeed, the band saw is my main issue. I am not brave enough to move 250lb of cast iron outside, so this is the tool that will always be used inside. And since I build SOF kayaks, lots of WRC will be ripped. The Grizzly 14" saw has only one 4" dust in the bottom housing. I am planning to use a Y and play around with a second dust input below the table.

    Having the dust collector run outside is probably the the most important thing. I am still not sure whether the lower static pressure of the G8027 is a disadvantage. Size certainly is, but convenience of emptying this thing is also an important point.

    Thanks again,
    Johannes

    The Oneida Dust Deputy (Post 6) works very well on most dust with my shop vac. It passes more plaster dust than I would like, but that stuff is very hard to separate. Other than that, very little sawdust gets to the shop vac. Large things like the odd plastic bag, long horsehair (my daughter the luthier rehairs violin bows) and paper towels pass on through. There is a larger version https://www.woodcraft.com/products/o...FQVqfgodZmgNvQ

    I think that the Veirtas lid in Post 2 would work a lot better with a Thein baffle.

    Everything you might want to know about DIY cyclones:

    I think the Grizzly G0738 is a good idea in addition to the vacuum collector. Having said that, I just use a good fan with a furnace filter mounted in a plywood box. For the money, you get a nice unit from Grizzly, but either way the air cleans up pretty fast.

    I think I will make one of these dollies to keep the vac and cyclone together.

    Furnace duct can be used to make a cone too. After cutting the angle, bend the last half inch over flat and it will snap into the fold to join. Not as secure as the factory fold, but that's what pop rivets are for.

    I have a grizzly 3 hp 220v table saw and a 2 hp 220v dust collector. The dust collector does an ok job and probably collects probably ?80% of the sawdust. This leaves a good bit to clean up or is floating around still. It’s an enclosed cabinet and I have to clean out the cabinet after projects. Moral of the story, you can’t have too much CFM. I probably would have opted for a bigger duster collector if I had knows about this 80/20 reality.
