Hey all,
I purchased a used 3HP Grizzzly twin filter dust collector G0562ZP (Specs Here).

Trying to figure out how to modify the connector between the impeller housing and the filter housing. I’d really like to be able to turn the impeller housing 90 degrees to the back ( so the inlet points down) so that I could mount the impeller housing directly onto a an Oneida Super Dust Deputy. But….the geniuses at Grizzly made the Wye rectangular instead of square. Thoughts on how to accomplish this? Each opening on the Wye is about 4.75” x 6”.

That is a tough one.
I am assuming that you want to eliminate one set of the filter and bag?
Are you going to mount this to the wall or keep it mobile on the cart?
If you are going to mount it to the wall then stacking it on a SDD should not be a problem. I removed the plastic wye on mine and used a HVAC fitting to connect the SDD to my blower.
I do not exhaust through a filter but go directly from the SDD to the outside via a dryer duct into the flower bed.

The difficulty will be the round to square opening issue for the filter housing. A local HVAC company could probably make an adapter for you fairly easy.

If you are going to try to keep this all mobile then this is a whole new beast. There are some pretty smart folks here. Hopefully one of them will have a good solution for you.

Please post your final results as I would love to see it.

Good luck with your project.

Would prefer to keep both filters. Would also rather it be permanently mounted vs. mobile.

What if you run a header from the impeller to the filters rather than using the wye? I realize the loads on the filters wouldn’t be even to begin with, but the SDD does a pretty good job so you won’t see a lot of fine dust in either filter. Additionally, the filter closer to the impeller would blind off somewhat and equalize out the pressure profile so you would wind up with the same amount of air going through both filters .

I had the same issue with my G0548P and since my shop is small (12’ x 24’) I had to get creative with how to put everything together to minimize the footprint. I ended up flipping the motor upside down and hanging it from the top of a 2×4 cage. Not shown in this picture are cross bracing I added to the back and sides to stiffen up the frame, it wobbled pretty bad before those were added. If this is something you think may work let me know and I can add more photos. Mine is on a mobile base so I can rearrange the shop as needed.

I would love some more photos! That basically looks like what I was thinking.

I put my HF DC blower on top of my Super Dust Deputy and changed the blower to 6 inch to match the cyclone. That required a HVAC fitting to be riveted to the HF cover over the blower and a little cutting with my Bosch jig saw. I wonder if you could not do something like this. Remove the cover over the blower where the inlet is and take off the existing fitting and add a 5 or 6 inch to match your cyclone. I had to heat up the cyclone to get it to go into the metal fitting but that worked well and made a nice tight connection.

Appreciate the advice, but I think the least of my issues is getting the collector connected to the SDD, rather it’s once I re-orient the motor housing, getting the filter housing connected back to it. If the connectors were square, this would be a done deal. :)

You are going through what I had to go thru. End result: had to goto local HVAC place to make the custom elbow. $30 from rectangle to circular.
I brought the rectangular piece with me so the person could have the exact dimensions to work with.

Sorry for the delay in getting these posted.

Here is the arrangement of the motor hanging. I checked all the combinations of ways the rectangular duct could be mounted from the motor to the canister without having to cut metal. This is the configuration I went with for the smallest footprint floor space wise.

This is the platform I made to hang the motor from. I glued up the double thickness of 3/4” ply to make sure the hardware wouldn’t pull through a single ply. The 3/4” ply boards are glued and screwed vertical so that the platform doesn’t sag under the weight of the motor. I mounted the motor with 5/16” hardware. I’d planned to trim the front of the platform flush but my crosscut sled fits perfect on top off it so I didn’t. I was able to lift it on top of the frame by myself but that probably wasn’t the smartest thing I’ve done. The motor is heavy.

This is one of the front corners. I did a partial lap joint so that some of the weight carries directly into the vertical board of the frame. I didn’t want all the weight to just be carried by the screws.

Here you can see one of the cross braces I added. There was a pretty good wobble front to back before these. I built a ply wood box that holds a 20 gallon metal trash can and the SDD mounts to. The dust in the bag was from when I overfilled the can while planning. I drilled a 1 inch hole into the top of the box that lets me check the fill level. I haven’t overfilled it since then but haven’t gotten around to emptying the bag. The red toggle clamp presses a piece of 1/2” ply over that hole when the collector is in use.

I threw this lovely piece of bracing together to hold the canister up. The black metal bar came with the collector.

It’s not the prettiest setup but it works for me. If you have questions about any of the other details let me know.

Thanks Arm!!! I appreciate it. Now, I gotta figure out the Tetris angle to this. :)

I think I spent an equal amount of time scratching my head figuring out how I was going to do it as I did building.

I’d recommend trying to lay the collector components out as best you can to get the general dimensions. The only plans I made were for the dimensions of the frame. After that it was ad libbed.

Good luck.

Arm3 – there is a lot of dust in the clear bag below the filter. How long did it take to fill it that full? I also noticed none of the clamp connections are taped with HVAC foil tape to seal them. I had a lot of large chips in the bag, which shouldn’t happen, so I called Oneida. They said the main cause of large chip carryover was air leaks in connections, especially on the cyclone outlets and the inlet to the fan. You might want to consider getting a roll of tape and tape those connections so they are air tight. Basically, you should not have any large chips, and very little super fine dust in the clear bag if things are sealed up well according to Oneida.

Earl, The dust in the bag is from two separate jointing/planning sessions when I was careless and did not check how full the can was before starting. I over filled it and that’s why the dust made it past the SDD.

Since then I added a hole in top of the plywood box my can sits in to make it easy to check the fill level. I use the red handled toggle clamp to press a plug into the hole when the collector is running.

Prior to that the only thing that made it to the bag was a small amount (less that a Dixie Cups worth) of fine dust. I should empty out the bag though to make sure I haven’t developed some other problem.

I think I have some HVAC tape I can put on the clamped connections. Thanks for the tip.

I saw a dramatic improvement in the performance of the SDD when I taped everything up, even spots I didn’t think would be leaking.
