I am building a shop.
My plan is to install the dust collector with the air compressor outside the shop and to run the the PVC or ABS piping for the dust collection right on the concrete slab (with all the electric cord to the machines) and then to build a tongue and grove plywood floor on the top of the mess to hide it and to not have to climb over it all the time.
What do think about this idea?
What did you do in your shop?
DO you have pictures?
Thank you.
Bert

At least you have a plan Bert, mine is still a work in progress so I have the DC unit on one side of the two car garage and all my tools that hook up to itlined up in a row with the hose on the floor behind them.

It can be a pain at times and I guess I am going to have to rearrange and mount some runs on the ceiling.

Mine is 2” ABS that runs up along side a cabinet in the engineered trusses to the far garage wall. Be careful if you use 2” pipe, sweep up the shavings (or put in a screen, like 1/4” hardware cloth) from your planer-molder first, or you can clog it. Most dust goes through just fine. I have Ridgid shopvac with a Dust Deputy on top to save space The whole thing works great.

As much as we all wish we could cut back on the noise, locating the DC outside the shop can play havoc with our efforts to heat or cool the space. You’ll be pulling a lot of air outside and will have to heat or cool the air that replaces what you pull out.

Sawkerf, I did not think about this.
What do other think about this issue?
I plan to use 4.00” tubing.

Bert,
We are same name….
I use 4 inches flexible hose. But you need to construct two boxes to have a somewhat called JUNCTION BOX. One outside and one inside. You need to put an inspection hole just in case blockade will happen. Mine is flexible hose 4” and I just set it aside when not in use. You need to insulate the box from weather condition. This is my suggestion only.

Hey Bert At the commercial shop I worked at, we did put the dust collection outdoors. It may raise some noise issues with neighbors, depending on the size and noise level of dust collecter. If it does you might be able to enclose in a small sound proof structure. In the unit we have, the return air was ducted back into building just above ceiling level. Then we had a larger grate in the ceiling with a furnace filter to help brake up the air flow and bring it back into the room. The return air duct is about 3 or 4 times larger than the main out duct. I’m sure your collector company can help with your duct work. As far as everything being under the floor we also have this, and it works wonderful. Of coarse we have a basement and crawl space beneath. If you cannot have this, I would suggest having removable flooring in areas where your mechanical is located. Just in case. We cannot put air compressors outdoors here in iowa, on account of it getting so cold and freezing any moister in the lines. Hope this gives you some more ideas. Sounds like your going to have a wonderful shop.

Hey Bert, I don’t have a big DC yet, but I’ve already installed 4” PVC hung from my ceiling. This is not bad, but in my opinion the best option is duct work. My neighbor ran his ductwork in his attic and dropped it down where he needed it. To be more specific where he has three tools on one wall he dropped down a leg and ran it to all three machines. As far as your collector being outside; I plan on doing the same thing. I’m going to pour a small slab and enclose it and put a roof on it. Running as much in the attic as you can will keep you from taking away from your ceiling height. Hope this helps.

hey bert…gary k put his pvc pipe in the concrete slab …he used the 4 inch i believe…i would’nt use anything smaller…your just asking or trouble..it will get clogged way to easy…if you want to put your pipe and electric on your slab and then have a wooden floor over that…that will work good…as you probably know…standing on concrete is very hard on your knee’s and legs…i have a wooden floor and i ran my pipe along the wall with down pipes to each tool..and one under the floor that comes up into my table saw…and have a blast gate at each tool..its the best way to go…....i hope you enjoy the journey of building your new shop…i loved building mine….grizzman

Bert -

Generally speaking, the bigger the duct diameter, the better the collection effeciency. My Jet 1100 cfm has a plastic “Y” at the impeller housing that changes the 6” impeller opening to two 4” openings. I’m planning to rework my duct system in the near future and will scrap the “Y” in favor of a 6” “backbone” duct with 4” and 6” drops to my tools and bench.

Rather than have ducting on the floor, I’ve selected a location for a riser that will be as out of the way as I can make it. Now, all I need is the time to get ‘er done. – lol

If your DC is outside and you have a gas furnace or wood burning stove, be sure you do not create negative air pressure as this will pull carbon monoxide into the workspace.

Bert,

I don’t have the luxury of a space outside my designated “workshop”. I use two long runs of 4” PVC grounded inside and out. The larger chip creators (TS, jointer, planer) are hooked to 4” PVC to flexible clear so that I can spot clogs. The smaller drops are farther out and use either 3” or 2.5” pvc to clear flexible. My setup is all drops from the ceiling (PVC on hanger tape to joists). I know that I lose some suction going from the ground floor to the 12 foot garage ceiling and then done again, but it works and gives me access to all joints if clean-out becomes necessary (and it does). I would really hesitate to enclose the ducts as it becomes much harder to spot clogs and fix them. But that is just my 2 cents. My system has been up and running, but seems to never be “finished” since August 2009. I love it, and wish I had done it sooner. No matter what you do, it will really increase your enjoyment and health in the shop.

Justin

CL810 excellent observation, I did not think about this. I can install a fresh air inlet into the shop to solve this issue.
Thank you all.

I vote strongly against putting the lines under the floor, in the walls, through the attic, etc.. A shop is constantly evolving, you’d be surprised how much the layout will change in just a few years.

As for the noise, I put my DC in a sound-deadening closet, see http://www.thewoodnerd.com/workshop/dustCollection.html for some details

How big is yoru shop? Mine is rather small so I use one of those telesoping hoses that go from 4’ to 20’ and use Rocklers dust right ports so I move the hose frome one tool to the other. Its a pretty good solution for a small shop, you could run one pipe to a central location and do the same, although if you are running from machine to machine it may not suit your needs.
