Cost of running 225mm PVC mainline ducting for Dust Extractor
I am very close to purchasing a dust collector that will allow me to run a 225mm main-line for my dust collection with 150mm from here to each of my tools. Apart from the lathe which I think I should run 225mm all the way (I am still investigating this) for each other tool, I think I would need to do the following:
- attach a wye reducing it to 150mm ($85)
- install a blast gate ($23.50)
- run 150mm straight pipe from the wye / blast gate to the outside of the shed (ie: run at 135 degrees to main line) ($25)
- at the shed wall, run 2 x 45 degrees bends to turn it to come down the wall ($30)
- run 150mm down the wall
- attach another 2 x 45 degree bends to bring it back around to tool ($30)
- do whatever is needed for particular tool, including flexi
So, as well as the mainline (around $240 for 12metres of 225mm) and the more expensive costs for the lathe, each standard tool will be at least $200 in ducting.
I thought 'holy s*** batman'. When I added in a floor sweep and vacuum I am up near $2k. My thoughts then were a bit more colourful in expression . At these prices I will have to give up alcohol all together and my main diet will be beans
See my spreadsheet - these are based on the best prices I could get in Port Macquarie and seemd to be comparable to Total Eden and much better than at least one other supplier
I am now thinking of:
- sharing more of the plumbing
* at least two tools per wye to 150 - maybe even one wye to 150 down either side of the shed
* perhaps even two tools (or more) after I have done the 2 x 45 degree turns at the roof wall line
- forgetting 225mm and running all 150mm
I am wondering if others have faced this and what they did. Also, if I have got the above right. If people think a diagram would help, I will draw one up using the trusty pen and paper
Note that I have not actually got a cost for flexi but added in an amount that I can change later
225mm stuff 150mm stuff costs straight 45 bend wye to 150 straight 45 bend wye Flexi per m Blast Gate cost 119 63 85 49 15.5 21 15 23.5 main duct 2 0 0 0 0 0 0 238 cyclone to impeller 4 0 252 lathe 4 1 337 bandsaw 1 0.5 4 1 2 1 246 tablesaw 1 0.5 4 2 1 225 router 1 0.5 4 2 1 225 drill-press / hand tools 1 0.5 2 140.5 floor sweep 1 0.5 1 1 1 169.5 vacuum 6 1 113.5 0 0 total 1946.5 assumptions: Drill press / hand tools runs from same 225mm off-shoot as lathe floor sweep and vaccum share the same off-shoot Last edited by mick59wests; 28th November 2013 at 09:37 AM.

Here is a shot of five of my machines that are serviced by only two 6" ports. Flexy hooks a machine to be used to one of these ports.

It was done this way for two reasons. First I was space limited. Second, it kept the length of ducting down, and therefore reduced costs and airflow losses.
You might try looking as duct design to try to reduce ducting costs without compromising performance.
Cheerio!

John,
thanks for that one. The 'purist' duct design (from my research) is to run a larger centre mainline and have all bits run off that. Yours is just 'slightly' different but from what I understand it works really well. It also looks like your blast gates are nice and handy whereas mine were going to be near the main duct, nearly 10' up. I may go back to my original thinking of running most of my machines down one wall similar to what you have done and just use 150mm everywhere while leaving a wye capped so I can expand later. I still need to investigate whether running 225mm to the lathe (assuming I have a CV max) would be better as this is my main machine and is probably the worse of all in regards to fine dust.
cheers

Hi Mick
I have just purchased my ducting from Total Eden in Brisbane. Most of my ducting is 150mm storm water grade. My machinery includes Bandsaw, Planer Thicknesser, Table Saw, Compound Mitre Saw & Drill Press. I will eventually add an extra outlet for my router table and wood lathe. These will drop from ceiling near my Planer Thicknesser outlet so should add only the cost of an extra Y and 90Deg bend.
My workshop is 6 x 12m approx and I have arranged my tools to have the ducting in 2/3 at one end
I placed my Cyclone in a back corner and ran the ducting along one side wall and down to band saw and table saw. Table saw has about 1.5 m flex to get out to centre of workshop. Just before the drop to the bandsaw there is a Y to produce a run across the workshop and down to to the Mitre saw on opposite side to Band Saw. Two Y's in this run across the ceiling lead to the ceiling drop for the Planer thicknesser and drill press on back wall. My workshop is too small to use the Table saw and Planer Thicknesser at same time so both are mobile and need to be shifted for the other to be used. Hence I could have used the same outlet for the Table saw and the Planer but the table saw is better with a duct outlet at floor level and the planer is better with a duct coming from the ceiling.
I have a Green Gate Dust Collector Controller with automatic gates so having blast gates up high is not an issue.
Total cost 279.40 to service 5 outlets. This involved
1 x 6m pipe ( I will probably need another) $66
5 x Y $50
6 x 90deg $36
4 x 45Deg $72 ( these are more Expensive because could only get DWV not storm water)
3 push on caps ( also DWV) $30 These are not necessary but I bought them to me able to use some of my machinery before all the ducting is installed. Installing my ducting is a little more complicated because I decided to put all the Horizontal runs above the ceiling to make the workshop less cluttered.
I will be very surprised if the total cost of my ducting exceeds $450 without Blast gates. I already had the small amount of Flexi I need
Hope this may help your deliberations
Cheers
Ron

Ron,
thanks for your post. It seems you have done similar to John in keeping your tools as close as is practical and only used 150mm piping. I think I will move away from the purist view and go more practical as $2K for ducting is over the top. The only thing I have on wheels is my tablesaw. I also noticed your wyes were much cheaper than mine. I was trying to make all tools in a permanent position with plenty of elbow room but I definitely should be able to make compromises with minimal impact to capture.
I don't suppose you have any photos......
cheers
Mick
PS: What do you mean not enough space in the shed, it is bigger than mine

Hi Mick
I looked at EziDuct clip together metal duct and that was going to be well over $2K and promptly went for PVC.
I have just finished my bottom Collection Drum this morning and should have the first of my ducting installed over the weekend. Will take some photos and post ( when I learn how) as the install progresses.
Will also post some photos of my collection drum as it may interest other installers.
Cheers
Ron
PS I misled you when I said my workshop is 6x12 m. Its actually only half this as the front half is occupied by Car, Boat, Metal Lathe & Milling Machine

Ron,
any detail you have on what you do will be greatly appreciated by me (and I am guessing many others). As you may have guessed, the more detail the better . Your trashcan setup would also be good.
If you do have problems with posting the photos but can send via email, send me a PM and I'll send you my email address and I will post them
cheers
Mick
