Dust Collector 6" PVC

[Bret Champoux]

For those of you using 6" PVC for ducting for your dust collector, how do you reduce it to the smaller ports on most tools?

Most of the WW outfits carry the adapters. I'm told that some combination of 6" to 4" PVC adaptor and duct tape works.

Penn State carries the most adaptors, fittings, etc., although WoodCraft, LeeValley and others carry fittings as well. Most tools use 4" or the standard shopvac 2-1/2"

Hope that helps some.

Bret,
Funny you should ask, I am working on my cyclone system and am in the process of running my 6" duct. This is the Y-Fitting I built using a 6" Y with a 5" gate and 6" gate. I installed the 6" gate and added a 6" to 4" reducer that will go the the Preformax. On the other side of the Y I installed a 6" to 5" reducer and put the gate on the 5" side for my bandsaw. I got the gates from Amazon and the reducers from Oneida.

Bret,

Plain old HVAC reducers do a nice job for your application. They are cheap and readily available at the big boxes or a HVAC supplier. I use a ton of them. You might need to get a crimping tool, some of the HVAC fittings need to be crimped to fit inside the PVC pipe and be sure to tape or caulk the joint on the reducer. They can be adapted to the wye's by cutting a 2" long piece of pipe, inserting that into the wye to take up the extra space and then insert the reducer into the pipe.

The best answer for your problem really is to change the ports on the tools to 6". HVAC register boots or starter flanges work great for this application. I did it on most of my machines and the performance difference over the 4" is BIG.

I haven't changed yet, but am considering changing from 4" to 6" main duct for my system. For most of my machines I will need 4" flex connections (I have most of the machines, jointer, bandsaw, planer, etc, along the wall and ocassionally need to pull them out a little to run longer workpieces). I am thinking that I can put my blast gates where I change from rigid to flex. If I do that and make my own blast gates I can make one side of the gate 6" and the other 4" thus accomplishing the switch without using extra fittings to reduce the diameter.

Hi Bret-

I was able to get PVC reducers at the same supplier as the pipe. I used 6" hose as close to the machine as possible. As luck would have it, the reducer fit snugly over the 6" flex hose. Smear a little clear silicone inside the reducer, work the hose in, let it set overnight and you're good to go. As I understand it, reducing from 6" to 4" as close to the machine as possible helps maintain CFM better than 4" hose.

My supplier is in Lambertville, NJ. The big boxes in SE PA. and NJ don't seem to carry 6" pipe or fitting . HTH

Curt,

What type of supplier did you use? I'm looking for 6" flex hose and can't seem to locate a supplier in NE Arkansas.

Clem,

The folks at Wynn Environmnetal have good hose at a good price. You might give them a call. Really nice people to deal with.

I'll call them in the morning.

Hope everything is going well for you.

Clem

P.S. I had hoped to get to your picnic this year but it was our wedding anniversary weekend and "we" had different plans. Maybe next year.

What??????? Missed the bbq just for your anniversary???? Well, I never heard of such!!!! ;) :D :D :D

Seriously,

You missed a good one Clem. Hope to see you here next year. Let me know if you are ever over this way, you are more than welcome here whether we are having a bbq or not.

Hi Clem

Wynn Environmental is good and they're really interested in the hobbyist DC/ Cartridge Filter market. Hard to find a 'professional market' supplier for small orders. Wynn in Willow Grove PA. is also 40 minutes from my house. ;) . However, before I learned about Wynn, I got my hoses from Amazon-Jet brand. Either the Wynn or Jet 6" hose is really flexible for such large hose- proportionately more flexible than the 4" black stuff you can buy anywhere and I think smoother on the interior.

Curt

P.S. Wynn may have a place in Tulsa so shipping might not be too bad.

I used a MDF sandwich to connect all sizes of fittings to the PVC.

Take two square pieces of MDF 2" larger than PVC (6" square for 4" PVC"

Put a blast gate between the two pieces of MDF, with a spacer/guide on each side of the gate slightly thicker than the blast gate. I used 1/4" ply for the gate, and the same ply for the spacers/gate guides with a piece of paper for additional space. Screw it together through the spacers.

Use a flycutter to cut the holes you need on each side. E.g. 4" on one side, 2- 1-1/2" holes on the other for miter saw and sander.

Attach to the pipe with a small screw through the gate assembly and the pipe with silicone to seal if you like.

I hate doing jigs and shop stuff, but I just couldn't see spending the money to hook up 8 or 9 machines.

Also used this method to make a box with two 4" outlets for TS and jointer.

Clear as mud?

John -

I think that was what I was trying to say in my post earlier in the thread.
