Topic tags/keywords: dust collection jet cyclone question

I’m looking for some advice on Large Dust collectors. About 15 years ago, the DC at our HS broke and was disassembled and never replaced due to budget issues. Currently, we run multiple small dust collectors (DustRight single ports) for each machine that we have. Not only does it get really loud, but I have to worry about each one actually being turned on.

So, I’m looking for advice/recommendations on large DC units. There are 4 machines that I’m trying to connect to: Planer, Jointer, Table Saw, and Router. A possible 5th machine (if the unit allows) would be a Belt/Disc sander (6×48 belt and 12” disc).

I’m debating over a couple models, but really like the JET model shown here.

Does anyone have experience with a DC like this? is there any other brands that I should be Considering? Will a 3HP motor be enough to collect from 4 heavy machines? Lots of questions I know!

Any help or suggestions is much appreciated!

Are all the machines being used at once? If so, then I wouldn’t think the Jet you mention would suffice. You’d want a much bigger motor, impeller, and 6” metal ducting. The one you are looking at would be fine for one machine at a time, but you’d need to install blast gates and have to open/close them properly when each machine is being used to get the kind of airflow you need at the particular machine being used.

One at a time, the 3hp would work but if any are going to be run at the same time, you’ll need 5hp and 8” ducting with 6” drops.
Running one machine at a time, you’d still want 6” ducting and connections to the machines.
Make sure you figure in the cost of the hoses, gates, ducting and clamps, etc as they add up and it’s not hard to spend as much on the accessories as you do the Dust Collection unit when you’re doing large sized ducting.

The Jet is nice, but it has a short cyclone which are not as efficient as the longer ones. Penn State, Grizzly and Clearvue make the larger style. One thing though, they need a much higher ceiling and none of the machines, whether the Jet, or any of these others will be quiet. They’re all going to be loud and I had to experiment with my system and eventually put everything into an adjacent room to help with the sound.

Thanks guys. Ceiling height is no problem as we have 17’ ceilings in our room. I’m gonna look into the Grizzly and see what they have available.

I had a 3hp cyclone Dust Gorilla and it’s great, for what it’s intended. It is not designed to be turned off and on with each use, like the smaller units. Too, the size of the lines and they type will, totally, change its efficiency.

Mine would run on a Unisaw with an upper and lower draw and very little escaped. That was with only four inch lines. Had I gone to five inch, it would have improved, according to people more knowledgeable than me.

Because I may have four items running, I have three collectors. The three horse collects for the table saw, jointer, planer and the sanding station. The horse and a half collects for the band saw, oscillating sander and the drum sander. For these two, a swap of hoses must be made at the collector/cyclone, which turned out to be as convenient as opening and closing gates, but without the loss adding Y’s and things give. The small, one horse is dedicated to the miter [and the lawn vac system posted elsewhere on this site].

Just jumping from the [temporary] four inch draw on the cyclone, for the four bagger, to a six inch hose made a notable difference. It works good enough to make least efficient collection point, my sanding station, pretty effective. If I swapped all the ribbed hose out for smooth tubing, the performance would climb enough to make it worth while.

In the end, I like having several collectors for a small shop, rather than a single monster running all the time. Setting them up with sensor outlets that kicked them on with the machine would make them golden. In your case, that would be far cheaper too.

Add to Woody’s list of collectors the Oneida. I own three cyclones and attest to that they are worth every penny.

Oneida will help you lay out the system for 3hp and larger units.

There is no reason you cannot build a muffler for your collector. It would look, suspiciously, like a room with vents.

The grizzly units will give you much more bang for the buck, and they are actually pretty well made. (This, from an Oneida SDG owner).

I have seen the grizzly units up close and they are built like a tank. I have the Clearvue so I have been able to compare. The thing with the Grizzly collector’s though, is that they are not very competitive pricewise as they as with their tools.
Once you get to the 3hp and 5hp cyclones, which directly compete with the Oneida, Penn State and Clearvue, Grizzly ends up costing more.
I have a lot of Grizzly tools in my shop and I was looking at their dust collectors but I couldn’t see spending that much more on their units versus the ones that are made in the US and have people you can talk to easily on the phone or e-mail to get questions answered.

I agree with Kelly. Call Oneida and ask them what they recommend for your situation. I have used them and have very high regard for their techs.

is dust collection something you teach in the high school class of wood working? hmm..wonder if the students in the auto shop could construct something from a 4 cylinder gas operated dust collection motor and impeller :)
