Discouraged On Dust collection Piping.

[Dave Monk]

Put my new dust collector together and put in a 220 plug. I have been in search of 6" sewer pipe and fittings to run my piping. I had no idea how hard the piping would be to find. I was wanting to run the 6" along the ceiling and drop down to my machines with a reducing Y to 4". Any thoughts or ideas would be appreciated.

Dave, go to the contractor's desk at H/D and get with one of Pros who do special orders. They know what they are doing and should be able to advise you.

I have bought 6” pvc from Lowe’s they had in stock, if no luck there any plumbing supply would have.

I can find 6" PVC. Being the walls are so thick won't it be too big?

I did buy some 6” from Lowe’s that was green it had thin wall don’t know if pvc fittings will work with it. I think the pvc would work fine .

unless you are running big planers and table saws 4 inch should be more than enough. how far of a run are you doing? rockler sells or did sell a pvc to dust collection hose adapter. i think they were about $6-8 or so. make sure you ground the PVC with a grounding wire kit to discharge static electric. how many CFM is your dust collector?

1538 CFM. I think I have come up with a plan of attack. Thanks for your help.

I once read that schedule 80 pipe is the correct size stuff for dust collectors.  Its not to code anymore so hard to find; but apparantly pool installers/maintainers use it.  I've never verified this though as I use a piece of 4" drier flex stuff.  It lasts me about 1 year with winter being what kills it.  The cold makes it brittle so keep it warm.

Hey Dave, shoot some pictures when you get it in place. Mine showed up yesterday so I'm getting ready to set one up also.

Don't expect to see any pictures very soon because I have to order some parts.  I talked to a couple of friends of mine that have a custom cabinet shop and they just got done putting in a system using HVAC metal ducting and are very pleased with the outcome.  They taped all the seams with metal tape. They used T's where they branched off the main line but I want to use Y's. I found some on line that the ends would work well for dust collection systems. https://www.homedepot.com/p/Master-Flow-6-in-x-6-in-x-6-in-26-Gauge-Flue-Wye-26FY6X6X6/202258555#product-overview

If you have a plumbing supply close ask them for 6 inch sdr35 pipe. It is thin wall used for drainage. The next wall thickness would be sdr21. 35 would work well for what you are doing.

Thanks for your thoughts. I decided that I am going with metal ductwork.  

[kywoodmaster]

I think you will be much happier that way.

I used 6"  metal pipe for my system,  Not spiral,      snap lock.

Metal duct is great, although it can get a little pricey.  The thin wall sewer and drain pipe (SDR35) is available from plumbing supply houses or large irrigation supply companies.  Moore Supply is the one in my area.  I have not found it at the big box stores.  I have some templates to cut holes in walls for 6" S&D pipe if you need them.  You are not that far from me (as Texas distances go).

I went to the link you posted and you are on the right track.  I am a retired Sheetmetal worker and have installed MILES of metal duct but being as cheap  as I am, I made my own wyes.  Had I known what little  they cost I would have bought the ones you choose in your link.  Finding 26 gauge 6" snap lock pipe may be a challenge.  I used a brush on sealer instead of tape.  Not pretty though.  I ran my 6" duct along the wall , on the floor.  This eliminates a lot of duct going up to the ceiling and back down to the equipment and to the dust collector. For flexible sections I used the cheap aluminum foil and wire duct.  Still holding up well.
