  • Dust Collection Guro Opinions

    For all you experts on dust collection, I'm sitting here planning the addition to the shop, and contimplating price, size, effectiveness of dust collection. Looking at 3 units, one from Oneida, Penn State and Grizzly. Though, as you all know, I hate green, I keep coming back to the Grizzly. Take a look, and offer your opinions.

    Do not consider the microns of the bags. Unless some drastic change takes place, I plan to vent outside.

      Woody,

      I ended up getting the Grizzly G1029. I like it. It works well. In hindsight, I would have gone bigger if I had the cash, space and experience. I also would have used 6" pipe instead of 4". Grizzly also has good prices on the blast gates and adapters. I got the cheap clear hose. I should have forked out a bit more cash for the heavier duty hose. I used PVC sched 40 and have not grounded it. I have not seen a need for it yet. The plumbing ended up costing more than the DC. I got a separator free with my DC. It works great. I would suggest it. It stops the small pieces of wood that get in the system from hitting the impellers. I also use the DC for vacuuming the floor and tools. The nails that get picked up (and toys) end up in the garbage can instead of the DC. There is a grid by the impeller so it also eliminated the clogs I would get at the DC (planer chips,scraps,toys)and the need to empty the DC bag. My only problem with the separator is that the holes are only 4". I hope to develop one with 6" holes some day. I see lots of people talking about one-micron bags. I use the 30-micron bag that came with it. I have an old furnace blower that I will use to make an air filtration system. Putting a lower micron bag on your DC will take away some efficiency. Although some will not agree with me, I believe a DC is designed for collecting bulk tool/wood dust, not cleaning the air. An air filter should be used for that. And,the DC is loud and annoying. I do not think I could deal with it being on for hours at a time.
      I used some of the pages below to learn about dust collection. I hope this helps.

        Most of the problem I've heard with a separator with 6" holes is that it tends to suck all of the chips out of the separator & on into the DC. By the way I have the same DC from back when it had 5" a entry into the impeller.

        I built a sheet metal enclosure to set on top of the bag rim & got to used diesel truck filters free from a trucking company & set them end to end inside the enclosure I can now feel the air flow at the throat plate of my contractor saw. The enclosure allows the air to flow from the outside of the filters to the inside & on up through the center & out the top. I have a heavy mill plastic garbage bag on the bottom with peel & stick foam seal tape where the bag clamps to the bag rim. I hope to have some pictures on my web site in the future.

          Vibart2,

          Thanks for the info. I did not know about the 6" port. I was thinking about using a 55 gallon drum or one of the plastic 55 gallon Pepsi syrup containers I use as floats for my pool cover to make the separator. If I could do it again, assuming cash and space, I would go with a 2 stage cyclone. It would be overkill for one machine running at a time in a shop the size of mine but then again, overkill is not always a bad thing. [img]smile.gif[/img]

          I would love to see pics of your setup. Post them when you get them. Always looking for new ideas.

          Thanks,
          Rob

            Rob,

            Most of the posts indicate that putting a lower micron bag on your DC does not take away from it's efficiency. This is due to the fact that 1-3 micron bags have vastly more holes in them than the 30 micron type, it's just that these holes are smaller to capture the really dangerous 1-30 micron particles. Why switch on a DC and have it really pump out into the shop a cloud of dangerous 1-30 micron particles? For $19 from Grizzly, you can get a 1 micron bag that will capture this dust. Any remnants can be taken care of with an Air Cleaner.

              I'm saving my pennies for an Onieda system. It's more expensive but after a ton of research, I think it's worth it. I also like the pleated filter that catches the really small stuff.
