I can’t tell you what the drop would be but I did a side by side with the HF dust collector running with no filter to get max capacity and there was no difference in drop between the super dust deuty, the metal one or a traschan separator lid, the molded plastic one. That was a major surprise to me. I thought the flow should have been much better on the dust deputy vs the trashcan.

Subjectively it is quite a bit.
With my underpowered 1 1/2HP Jet I’m not getting much dust out the exhaust. I can’t give you numbers.

I think it also depends a little on the size of your collector can.

You did seal the collector can lid, right?

I have the Dust Deputy sitting on a 30 gal trash can and it has a very good seal on it. When it is running I can lift the whole can without the lid coming off.
Should I get a larger trash can or a 55 gal drum? I don’t really know if that would do anything to increase the air volume with the Deputy connected.

I talked to tech guy at PennState Ind the other day and he basically told me my 1100CFM blower on top of the Super DD is “mickey mouse” and I needed at least 500 more.

I’ve been looking for a blower/motor unit.

I am quite sure the Harbor Freight doesn’t have the horse power to really compete with some of the other dust collectors out there. I have been thinking about upgrading to a larger dust collector and continue using the Super Dust deputy with the new unit. I don’t think it is necessary for me to go and buy a cyclone collector since I already have the deputy. I will probably just get a higher H.P. unit an hook it up the same way I have it now.

Is this correct thinking or am I wasting my money by not going to a collector with the cyclone already attached.

The limiting factor on the dust deputy with a higher rated motor is the inlets and outlets on it.
I believe it’s 5” in and 6” out.

When you start getting into higher horsepowers, you will need 6” in and around 8” out to start.

Now, you might be able to get away with it at 3hp as I think that’s the largest Oneida has rated for the Super Dust Deputy but you’re really going to want 6” for your ducting and connections at the tools.

I only have 1 machine connected to the dust collector at a time. I just don’t have the room to run ducting all over the garage.
That being said, I could still have a somewhat larger unit just to get the CFM up.
With the Harbor Freight being 1.5 H.P, I could go to possible a Grizzly that has a true 2 H.P. motor with a larger impeller without having to run ducts all over. Or am I not thinking correctly on this idea?

P.S. Sorry for the doubble post

I think you’re missing the design intent of the Dust Deputy and trying to make it something that it’s not. A Dust Deputy is designed to be used with a shop vac. It is NOT a separator for a large shop dust collector. The inlet and outlet sizes should tell you that. I have a Dust Deputy that is hooked in line with a re-purposed central vacuum cleaner that I use when doing scroll sawing and sanding with a ROS and 1/4 sheet pad sander. It sepasrates the fine saw dust to keep the vacuum filter from loading up. It does a great job for this purpose. I don’t try to use it to collect sawdust from the planer, table saw, etc. This is a job for a full size 1 1/2 – 3 hp 5 – 6” piped system dust collector like a Clear Vue.

I believe you’re thinking of the standard Dust Deputy. The Super Dust Deputy designed for dust collectors, not vacuums.

Steve, what kind of hose/ducting system do you use? That also can be a factor in efficiency. I have a Thien separator on my HF DC, and with a ducting system and minimal hose, it works well. There is a CFM drop, but the CFMs are adequate. I wanted a Super DD, but didn’t want to spend the money!

Even if one at a time, with a 4” hose and 4” ports, you’ll hit a max cfm that will not come close to what you’ll need that some machines can produce.

It all comes down to your goal. Do you want something that can keep chips from accumulating on the floor or are you wanting to keep the find particles from getting into the air?
There’s no right or wrong, just what you reasonably expect the dust collector to do.

Steve,

Can you tell us more about your setup to include dust collector, inlet/outlet attachments, pipe runs, hose runs, etc. so we can get an idea of whats going on. Thank you sir.

My setup is very simple:
Harbor Freight Dust collector, Wynn filter in lieu of the bag that comes with the collector, Super Dust Deputy (Plastic one) sitting on top of a 35 gal trash can and is sealed quite well.
The hoses are all 4” and are also sealed well. As far as I can tell, I don’t seem to have any leaks, because there is very little dust coming from the unit.
I even have the plastic bag taped to the metal ring and get no dust leak from the edges.
I have the Rockler plastic hose connected to the unit and only hook it up to one machine at a time.

I have a Bridgewood 105A, 1 1/2 hp collector that I am converting with the 5” SDD and a Wynn nano filter. The opening in my fan is 4.5” and the SDD has a 5.5” outlet. Does anyone know if I can open up the inlet hole on the fan to 5.5”? I want to mount the SDD directly to the fan and reduce airflow disruption as much as possible.

Thanks!g

Just because you can lift the can doesnt mean you have a good seal. It just means you have a pressure drop. Just sayin.

There’s not a simple answer to your question that some engineer can spit out at you, as the net air flows are determined by the intersection of a system curve and the blower’s fan curve.

The Dust Deputy changes your system curve and increases the system loss, but just as much (and quite possibly more so) the additional length of piping (especially if you are using flex pipe with a tight bend radius) will result in a more negative effect than the DD.

Calculations aside, the proof is in the putting, and the best way to answer the question you have posed is to measure the air flow with and without the DD. The best way to do this is with a manometer, but the little propeller spinners that you plug into your phone and run with an app can be had for <$50 and allow you to assess changes to the system set up well enough.

The best ways to improve your system performance is to:
1. use smooth wall pipe
2. use the shortest pipe runs possible
3. avoid tight radius pipe bends (of course the long sweep elbows cost a small fortune)
4. minimize the total number of pipe bends.

If you’re stuck using 4” flex and have a several Y’s and tight bends, you are going to have very high system losses and there’s really not much you can do about it.

Hello GuyF,

I have a HF DC and your Bridgewood looks very similar, I removed the fan cover with the 5 inch suction side port and replaced the cover with 6 inch HVAC take off ($5.99 Lowes ) this six inch take off fits perfectly into the 6 inch suction side of the Supper Dust Deputy. The air flow differance between the 5 inch and the 6 inch is noticeable unfortunately I do not have a pitot tube to measure the difference. I will measure the current draw with an ampprobe and report back.
My impeller looks to be a little different too, my blades are tilted in the direction of fan rotation and fan is a 9 3/4 diamater. Seeing the difference from the 5 inch input and the 6 inch has convinced me that using 4 PVC instead of 5 inch is a real deal killer. I will use 5 inch HVAC duct and tape with foil tape along the joints as well as the seam at the snaplock. I found a local sheet metal shop that will make my Wyes’ in 5 inch for $30.00 each a little pricey but I think it will be worth it. I will be using a Wynn 35Anano filter also. The motor and fan will be mounted in a vertical plane allowing the shortest pipe runs about 4 inch between the fan and the SSD. The exhaust will be into the HF bag holder with the filter on top. The tools that will use this system is a Ridged 4512 TS 12 Dewalt Planer, 8 inch Delta Jointer.
And. 12 compound sliding miter saw. The MS will be the trouble maker for dust collection. My idea on that is making a frabric shroud in a cone shape that will allow the Saw to articulate in all directions and still maintain some semblance of dust extraction. That is my plane if anyone has any suggestions I am all ears.

Steve, I think your 4 inch hoses are causing your biggest cfm loss. It requires a massive amount of flow, with a 4 inch pipe, to keep the same cfm that a lower flow will give you with a 6 inch pipe. I am in your same situation, I have the Jet 1100VX-CK dust collector and it has been doing a good job but I have just added a Jet 22-44 OSC drum sander and it creates such a fine powder, compared to my TS, or my Jointer/Planer, that my system needs some help now. I plan on adding a Super Dust Deputy and making it a 2 stage system. I am in the same boat as the rest in trying to decide how best to make up the system. I am going to talk to Oneida and see if they think the regular SDD of the XL would be best. With my 100VX I think I am right on the edge with the XL.

My setup is like yours, small area and only one machine in use at a time. I plan on mounting the impeller section on top of the SSD for minimum flow loss. The Jet has a 6 inch inlet but the output is only 5 inches. I don’t think the outlet is as critical as the inlet though. I will try and minimize sharp bends, to keep up airflow but I plan on using a long section of flex hose, from the SDD, to connect to my various machines and I know that will cost me some flow. I will either run 5 inch, if they recommend the SDD, or 6 inch, if they recommend the XL, hose and use a reducer, to 4 inches, at each machine, it’s just not practical to try and increase the size of the dust ports on my machines larger than 4 inches.

I have purchased a cheap air meter and will take readings before and after the changes. I am hoping to keep cfm loss to a minimum and will post my results when I get the system up and running.

I’m sure there are others here with more knowledge about airflow, but it seems to me you are choking it down with 4” pipe and expecting 6” airflow.

Concerning the Bridgewood DC, YOU have a 1.5 HP with about a 10” impeller. You are not going to get enough cfm with a 6” hose to have adequate air speed. You would be lucky to get 600 cfm with that machine and probably less.

The inlet to the DP is 6” the duct work is 5”. I have reducers at each drop to the machines. I have blast gates at the wye close to the collector to minimize loses as well as at each machine. In the drawing below you can see the duct runs in yellow.

Are you still concerned about airflow with the 5” duct vs the 6” mentioned?
