OK, guys and gals, I just became the proud owner of a Grizzly G1028Z/G1029 (I’m not sure which one I have)DC. I think it’s the G1028Z (see pic below) because it is 110V. Have to research that some more. It’s just too damn cold to go out to the unheated shop. Picked it up from a fella that was moving and didn’t want to move it. It was either put it in storage or sell it.

I have absolutely ‘zero’ experience with DC’s. I need help in setting up the ducting and hooking it to the different machines in my shop. From what I’ve gathered so far, I need to do a little redesigning where my machines are located. It appears for ease of ducting and use they need to be close to the walls. Which in my shop means some things have to be moved, and others ripped out.

Any help and advice will be greatly appreciated.

I would suggest reading this site thoroughly:

If yours has the cartridge filter, I have a similar DC (Jet version) and I hate it. The cartridge plugs up constantly, and kills the performance. I am planning to sell it someday and replace it with a cyclone. If I was going to do it today I would buy a ClearVue or an Oneida V-series. Both of these do a good job of separating out the fine dust before it hits the filter.

With a 1.5HP collector, I would run 6” ducts but keep the runs as short as possible, and keep the filter clean so that you can pull enough CFM to clear the fine dust. I run 6” PVC, with long sweeps for bends. I use two 45” elbows with about 12” of pipe between them to soften the corner. Run the 6” solid pipe as far as you can, and then use flex for only the last couple feet if necessary. Use good metal blast gates. I get mine from these guys:, and they are solid, tight, and a good value.

I have modified my band saw to allow a 4” connection, and my table saw to allow a 6”. The trickiest tool to collect dust from in my shop has been the SCMS. I have come up with a decent setup, but unless my filter is clean and bag is empty, it is marginal. A 3-5 HP cyclone will solve this problem for me someday.

Good luck. It is a lot of work to get this right, but you will love it once you do.

I have for the most part the same thing only made by delta. It is 1.5 HP as well with 6” going from the blower to the cartridge same as you, and 4” to the machines as does the Grizzly. There is one difference I have a big filter on top with a crank that knocks off the dust from the filter cartridge with a plastic bag on the bottom “used only 2 for going on 3 years but need a new one now” I put about 500 BFT of lumber through the planer alone so it has been a good DC you can get the disposable bags at Wood Craft. So look into getting a cartridge for the top maybe. I use all 4” connections with 2 blast gates at the DC unit and no more then 10 feet of flex hose and a quick disconnect at the machine “slip on slip off”, very easy and the system works like a charm. I did however add one thing 1/4” screen inside the 4” ports bend it like so ” ] ” put a sheet metal band inside and rivet it to the unit then seal the rivets with epoxy and smooth as best you can. That will save your unit from destroying the impeller blades because no matter how careful you are something big will get sucked in at some point.

PS. Check and see if you can rewire the motor for 220VAC for better efficiency

Good Unit by the way

I am a newbee but have many experienced woodworker friends…I just bought a Jet 1 1/2 hp DC and the advice they gave me was to first get a separator for it. This is a garbage can (most any kind will do) that has a plastic lid with a 4” in and out holes (google dust separator or Rockler has them too). Anything that is sucked in will have to go through the saparator and the big pieces will fall to the bottom of the g-can the small lighter dust will enter your DC. This will help you protect your impeller and also be much easier to empty the can of heavier chips. good luck and you’ll love your clean shop, and be safer too!

Separators can decrease the efficiency of the unit slightly and you still need to have a filter in-line which is why I use a quick disconnect. As you may know PVC or plastic should be avoided because of static electric setting a fire (you can do a search here and see a few members have had fires) or go through the grounding procedure for the whole unit. IMO if you get up into the larger cyclone systems then you may need to think about runs and CFM.

Have your say...
