Topic tags/keywords: dust collection exhaust pvc vs metal shop setup question

I have been in the process of a shop renovation and I have finally upgraded my dust collector and can now locate it outside of my shop space which is limited to 12X24. I am trying to decide whether to go with Metal or PVC? I have the means to heat and shape 4” PVC, and I know that there is a static electricity issue if it is not properly grounded, but I am looking for some feedback so that I can better make my decision.. The system layout is going to consist of one run going under the floor and rising in the vicinity of my Table saw and router table. The second run will run thorough the the rafters and “T” to accommodate dust requirements at each end of the shop.

Sticking to your question: I would use whichever is most available to you and the cheapest. If the floor run will be in concrete, I’d use PVC…no deterioration issues.

IMHO, and based on some research, this is way over hyped in hobbyist situations. i use sewer and drain pipe for the BORG and it works well. the pipe even fits into the plastic blast gates i get from rockler (when they are on sale http://www.rockler.com/product.cfm?page=20380&site=ROCKLER ) adn , with 1/4” weatherstripping, over teh inlet to my 50-850. if you’re interested, this pic shows the bar code for a fitting in the system. use it to locate the same stuff @ your local BORG.

and any “t” type fittings should be a t-wye fitting so the air flow can move freely.

I just started plumbing my system last night for the second time the first time My DC plugged at a 4” flex hose and collapsed 25’ of 7” HVAC pipe. It was salvage from a job. The project went on hold till I had more money. I just picked up the pvc yesterday. It is 6” sewer and drain, with rubber gaskets in the end bells and fittings. I got 5 90’s, 2 45’s, 1Y, and 42’ of pipe cause it came in 14’ sections, the total cost was like $280. on a side note after getting it home and handling it, man this stuff is huge. I will blog when its done.

My personal observations have been it depends upon the weather, primarily humidity, if you are going to have a static problem. I live in a very dry climate and have noticed a substantial build up of static electricity on my shop vac and DC hose. I only use a 10’ DC hose and during the summer the dust clings to the outside of the hose like a magnet. I have had quite a few large shocks when I touch either hose. My feeling is that there could be a problem if the PVC is not grounded. However, in your situation of running the main under concrete you are essentially grounding the system, but it is isolated. I would run the PVC in the concrete and metal above ground with flex to the machines.

I like pvc and you can make your own fittings much cheaper than store-bought.

Thanks to all for the great feedback. I would love to be able to pouring concrete but that is not my reality today. I am considering running under the shop similar to what shipwright posted “thanks” but under my shop is not enclosed. Since I live in Virginia and the summers can be rather humid I am also considering wrapping it with a insulation moisture the barrier. PVC is starting to look like the way to go… toolie thanks for the info on the fittings that would make life much easier…
