New Oneida Dust Deputy Plus

[RFGuy]

Yeah, I agree that the New Brit Workshop covered it okay in that video, but there is actually a better video from him. Unfortunately, I can't find it right now. In the video that I remember he not only measured the static pressure (suction) of the Festool vacuum but he also weighed out an amount of sawdust before and after to confirm how much the cyclone trapped, i.e. to calculate cyclone efficiency. I think it really comes down to the application. IF you have a relatively low volume of dust to capture then you need more static pressure. This is why vacuums do a good job of capturing dust from hand tools like portable sanders. On the other hand if you have a high volume of dust/chips like from a jointer/planer then you need airflow more than static pressure. This is why proper dust collectors do better at capturing more dust form tablesaws, jointers, planers, etc. For small shops like mine I use a Festool vacuum for hand tools and I used a ShopVac w/cyclone for the Mark V. It works, but I am sure a proper dust collector would do better at capturing dust from the Mark V, but maybe only marginally better since it only has 2.5" ports.

Keep in mind though that if the new dust deputy diy plus has 20% better airflow then it likely has less static pressure loss which translates into more useable static pressure (suction) from the vacuum. This may translate into improved dust collection depending on the tool and the vacuum behind the dust deputy. However, if you have plenty of margin on static pressure with your vacuum + cyclone then it may not matter.

P.S. Here is the other New Brit Workshop video that I was talking about where he measured cyclone efficiency:

Yes that is a whole different system. It would have been interesting to see how the system I have would fair against the festool system. Very little dust makes it to the ct26. I'm sure it no where near 80% where he had been guessing and more then likely very near the 98% point that the festool one gets. That is true on my other shop vacs too. Of course the collected dust in the vac bin/bag is almost none existent, the filter may get more then that shows but even that stays pretty darn clean. Of course I'm talking my shop conditions and not for what your shop may experience. The festool sanders with the bag installed also does a pretty good job, much much better then the other sanders I own.

It is interesting that for things like sanding you actually turn down the dust extractor to keep from getting too much pull down on the sander. They still do an amazing job of getting the dust! Well of course that is a major selling point so I guess I shouldn't be to surprised. So what happens when you gain 20% air flow on the low setting? OH well that is another whole ball game.

I was just out at the Oneida site doing some research. What interested me is the statement: "Now 20% more efficient with Neutral Vane Technology, its unique design uses centrifugal force to remove over 99% of airborne dust and debris before it ever reaches your filter!" If we look at that 99% number then it brings to mind that it is now 99% so that is the result of the new technology? So if we do the math and take the 20% off then the old numbers they use to post have to off massively. ie if something were 90% and we made it 20% better we would end up with what?

Also no where does it state the airflow is 20% better, so again what does all this mean?

I have sent them a message so we will see what if anything they say. Are they are missing the "up to" before 20%. I mean if you are 99% efficient gaining 20% amounts to almost nothing.

Ed,

It'll be interesting to hear what Oneida says, but I am pretty sure the "20% more efficient" statement only applies to airflow. This was demonstrated in the video that I posted originally. The Oneida website now says "capture and remove 99% of dust and debris" for the dust deputy diy (original) model. I looked at the Internet Archive from 2019 and it said "removes over 99% of dust and debris". Slightly different wording but the point is that it was 99% efficient at collection before this neutral vane. Presumably this new dust deputy diy plus model only came out recently because I didn't see it on Oneida's website last year. So, I am fairly certain that the collection efficiency hasn't changed for this cyclone, but it now has less static pressure loss which results in 20% more airflow. Probably a better way to state it than for them to say it is "Now 20% more efficient". Bottomline is this cyclone has always been over 99% efficient at dust collection.

I stopped using a shopvac as a dust collector back when my first one started producing smoke. I took that event as a sign that I needed a real dust collector, so I have G0583Z with a 10', 4" diameter hose connecting to a reducer that connects to the dust deputy. From there I use about a 2', 2.5" hose to connect to the planer. I realize that the 10' hose probably limits my airflow some, but so does the 2.5" connector size on most of this. I only use this setup for the planer. For all other tools I run the DC directly to the machine with the reducer directly at the machine, with the exception of my G1023RLWX that has a 4" port directly on it.

Yeah, but some of us can't easily fit a dust collector in our small shops and a ShopVac + cyclone can be more compact so it is a compromise. I hope you are using a Super Dust Deputy and not a dust deputy with the G0583Z. Each size cyclone is designed for a particular range of airflow. Reducing and constricting the 800cfm airflow from the G0583Z to go through the smaller dust deputy is not desirable. What size ports are on your dust deputy? It should match closely the inlet port size on the G0583Z which is 4".

My Dust Deputy is the little clearish/white one that is attached to a bucket. It has about 2-1/2" ports on it. No, it's not sized appropriately for my DC, but then my DC isn't sized right for the Shopsmith Pro Planer, which only has a 2-1/2" dust port on it. I only use the dust deputy when I'm using the planer, as it generates larger chips that clog the input cross-hairs on the DC, plus it would fill the bag rather quickly. The dust deputy was actually a curb side find about a year ago. Don't really have the space for a full sized cyclone.

My shop is actually just a 13'x26' breezeway between the garage and house that's been mostly enclosed. Being a breezeway there's a requirement that there's always a clear path between the 4 doors, one on each wall. Also there's an upright freezer in it. I haven't tried putting a full piece of plywood on a saw in this shop yet, but I think that'll be my tightest job to perform in the shop. At the moment running these 9' long cedar boards through the planer is enough of a tool position balancing act. For storage of smaller items I have about 8'x26' of space in the garage next to my shop. Still, it's more space than I had in my last house (half of a 2 car garage with the same walkway and freezer requirements).
