    Question Ducting Supplier (Extraction)

    Hi all - it's time to put in some permanent 6" backbone ducting in the workshop so I can stop dragging the duct collection unit around (will be about 4 locations with 4" gates / flexible hoses to machines).

    Anyone got a recommended supplier in Perth for steel duct? Want to look at this option before I go to PVC (storm or DWV etc). I suspect PVC is the way to go (speed, ease, reliability of assembly)...

    Cheers, Anton.

    It sounds like you should do some more reading on this forum.
    What sort of DC and machinery do you have?

    While you are at it, what about locating or enclosing and venting the DC outside? This is the single most significant improvement you can make to shed dust extraction.
    Also if you go to the trouble of installing " ducting you should seriously consider going 6" all the way to machinery and open up the ports on the machinery - this is the second most significant thing you can do.
    If your DC is up to it, 6" ducting can carry 3 times more air and dust than 4".
    If you don't do this all you will end up doing is not capturing sufficient dust at the source of production and it will contaminate you shed..

    Make sure you are sitting down when you get a price for 6" steel ducting and junctions. As for PVC, you will find it hard to go past Pipeonline.com.au.

    Out of curiosity, should those of us looking to build/install a system be looking at their PVC Stormwater pipe (which I imagine is the sort carried by most hardware shops), or are we better off looking at another type of pipe (e.g. their air pipe)?

    The "air pipe" shown at the Pipeonline website has a high wall strength and is quite expensive. It is designed for compressed air with internal pressures of 100+ psi. Dust extractor ducting is not under pressure but under a vacuum of <1 psi so it does not need to be that strong. I should not be floppy like AC ducting so something like Stormwater pipe is more than strong enough.

    Midnight Man. I looked around at different pipe materials etc when I built my system and PVC, with its collection of available fittings, was by far the cheapest. The mistake I made was getting DW pipe instead of Storm water pipe. It's thicker and heavier than storm water. It's only saving grace is it's ID is closer to 150mm than Stormwater so it suits metal 150mm OD duct fittings which I used on my saw table and router table.

    If by hardware store you mean Bunnings, i've noticed they generally stock the more expensive storm water pipes which as mentioned above isn't needed. Head down to your local reticulation/plumbing supply store and as for DW pipe. Its thinner, easier to cut and cheaper.

    The downside to the specialist stores is they generally only sell pipe in 6m lengths so good idea to plan ahead

    The DW pipe which is available from local suppliers (which I bought) is thicker than Stormwater pipe and has a rougher inner surface. I posted some pics in an earlier thread. I find it and post a link.

    The DW pipe sold by a local hardware chain and also plumbing chain is thicker than Stormwater and has a rougher inner surface. The top pipe is Stormwater and the bottom one with blue walls is the DW.

    You will easily use up a length of 6m ducting even on a basic system the spare pipe can also be used to make gates and BMHs.

    agreed, but the fact that I have 2m sitting in my back yard says otherwise...

    About 6 months and yes definitely been thinking about adding more ducting, the biggest issue is space and time to adjust the setup.

    Bob, you forgot gas powered Spud guns.

    Although technically illegal, seen a few clowns with one that they made, while i was camping near Fraser Island

    it worked well, not sure if they are still alive.
