    As I stated it’s the SECOND filter. Just to clarify further, it’s in parallel with the existing pleated filter so it’s similar to the set-up of a 3hp unit.
    Bill does have a vestige interest.

    Just buy the dc3 from Hare and Forbes. Don’t worry about modifying anything, they work fine as they are, and certainly better than any shop vac. Spend your time making stuff, not modifying something because all and sundry tell you to.

    well said river. Most dust I get from my 2hp is when I start it up and the top bag suddenly inflates with a pop and so much dust is released. I shake it out when emptying the lower but it soon gets bad again. Spose I could fit a pleated but I reckon one better would be putting the contraption out side. Seems to suck up 95% of dust at source all the same. Another thing I like is room air changes with fans but here we go down the modification/not making stuff route.
    Im presently dragging the fitted flex from one machine to another eagerly awaiting my 3hp Timbecon cyclone. But that’s mostly because it’s got that wheeled waste drum on it which I’m hoping will make emptying half as much of a chore, as well as the pleated.

    I’m with riverbuilder.
    The main reason I went for the modification route and 150mm pipe was that my workshop was too small to house the DE. Built a small shed outside and made the mods to improve the efficiency due to the longer run. I did splurge on equipment to measure air flow so I could see what mods were beneficial and which one weren’t. For instance I found the wok modification worked great at putting more chips snd dust down in the bag and rather than in the pleated filter but it reduced the flow.
    I’m only a hobby woodworker so I’d rather spend my limited $$ on equipment to help me make what I want to make. The extraction control system I have in place, as listed in a pre ious post, works a-treat for what I do.
    I think the point is, if you have the $$$ to afford both the woodworking equipment you want plus a Clearvue or flux or other high end extractors, go for it but don’t be put off from woodworking because you think you have to have such a system.

    While I agree in most cases, the difference here is the OP said he was setting up as a business so he's obviously not a DIYer and needs to think a bit more carefully about it.

    However, even for businesses it depends on what is being done.
    My mate has a WW business in a 140m^2 with 4-5m high ceiling workshop where he makes wooden work (woodwork/leatherwork/quilting/jewellery) benches. The workshop has huge roller doors at each end of the shed facing the direction of the summer easterlies in the mornings and the Fremantle doctor in the afternoons

    He is the only operator and buys most of his wood at or close to final cross sectional dimension form. He does some thicknessing of pieces to make bench tops, otherwise he is mainly cutting up sheet good on a panel saw and cross cutting with a drop saw. He has 6" ducting attached to a 3HP DC located inside his shed but next to the rear roller door . We've done a weeks worth of dust measurements in his workshop with my particle detectors in his workshop and it did not even come close to reaching any sort of OHS dust level.

    The opposite situation to this is a pokey DIY shed where someone (eg a retiree) is ankle deep in sawdust from reprocessing timber, turning or using dusty power tools for most of their day.

    He may be setting up a business but Post #3 re ClearVue and Flux

    “Thanks havabeer69.. but those are way outside my price range. it's only a small workspace.”

    No one said Not to buy/use/acquire a dust extractor. It’s all about buying one to suit the budget and using it. I for one would not run a pleated filter or needle cloth DE inside my shed but then again I don’t have wide open ends of my shed like one would have in a two car garage or a purpose built shed.
