    Looking for a decent dust extraction system for a small woodshop. Needs to cope with fine dust up to chippings from my joiner/planer.
    Any help with flexible hose and blast gates would also be useful.
    Cheers.

    There isn't one solution.
    (Personally, I use niflisk 26 hower, via my home made dust separator (ex Wax 240v))
    This + hard tub will make it easier

    +Any decent powered hower

    Critically for routers, hand Sanders, you'll need "auto power take off"

    For heavy machinery you'll need something like

    Anw have a read for more insights, ideas for a 110v solution here

    Critically in 110v there are very few, that would cope IE router cutting worktops or planing, except Festool midi.
    In 240 there are plenty of decent power alternatives

    My Makita VC2012L is available in 110v, did consider 110v, but I regret not getting a M class extractor, but cost is crazy, so settle for hard tub.:(

    Make one. Go on YouTube and you can make one easy enough and connect to cheap shop vac with lots of pipe over head to different tools. Pipe can be bought from screwfix if they still sell but online only.. Look up.. How to make a dust collector.

    You can use 32mm waste water pipe around shop. I would use solvent weld black and that could be run over head and around cheaply with clips. You then need a power take off vac £80 ish so it starts when tools power up. You may need some hose if vacuum doesn't come with enough like 5m of Henry hose off ebay. This can be attached to all the machines. Then make a dust collector from discarded Dyson cyclone to collect dust and bits or as I said make a nice one out of bins following youtube tutorial. They are supposed to keep maximum suction and more fun making yourself.

    Don't be fooled by this M class nonsense, I bought a M class Dewalt and found that the only difference between that and the standard equivalent is that the M class had a really annoying buzzer that would sound every time it thought the hose was blocked (in other words every time I used a narrow aperture dust port on a hand tool!) THE FILTERS ARE JUST THE SAME!
    I had to disable the buzzer in the end and now that I have made a Thein baffle seperator for it, it works a treat. Powerful enough to handle large stuff from my 10"planer but can also use on small tools.
    I have a boom arm and a remote switch and can reach all parts of my small workshop.

    Conection a bit ropey here, so didn't get to edit reply, I should have added, Festool L and M class, the only diference is a audible alarm on M class, but I found the cartridge filter is marked as M class on both machines.

    Couple of things. It's quite likely that the filter will be the same in both L and M class - manufacturers don't want to keep lots of options. The M class designation isn't just about the filtration, it's also, as has been pointed out, necessary to have a filter clog warning, and also the machine must pass several other tests like filter durability picking up carpet tacks (really!!) most of this is just cojones. The problem is the HSE in their wisdom have dictated that vacs for construction sites should be M class, so guess what the big contractors want to see.....

    Second point on power take off. Virtually all "smaller" 110v vacs have a 16A plug, which means technically the max you can draw @110V is ~1700W. If the vac takes 1000-1200W, it doesn't leave much for the power take off, if you are not going to draw more than the plug (and possibly the cable) is designed for. (It appears in practice you can draw more than 16A from a 16A plug on a 110V system without blowing anything, but should you?) I can tell you that in the not too distant some M class machines with 32A plugs and genuine 1500W power take offs you can run all day long without warming up, will be appearing on the market. Keep your eyes open - can't say where from because that would be spamming.

    Cheers guys, think I have enough to think about there.

    Blimey. Op only wanted a workshop vac. I have big old auto clean festool vacuum and dustless sanding kit and the cost of it all I need a security escort. Cheapo auto take off vac with self made collection box thing and a few pipes around is all that's needed for home workshop. Stainless steel Lidl/aldi vacs are good... Vorsprung durch Technik... :)

    Re post above... Yeah. That's the one. Bargain. Make a collection box and it's perfect. I don't need one but for £70 I'm tempted. No I can't. Somebody stop me :)

    Right, after almost going blind looking at all the websites that sell dust extraction systems, I've plumped for this one. It should do the job I want it to but I'll only be connecting it to three machines to start with. My table saw, mitre saw and planer. Later I'll look at connecting it to my band saw too, but I want to see how it manages the three first.
    I'll use four inch pipe on all and fit some blast gates so I have maximum suction on the machine I'm using.
    Any thoughts guys. 20180706_202039.jpg

    When I was looking at dust extraction my main concern was air quality, sure it will extract large volumes of debris, but something like that for me is a no no because it only has that bag at the top to stop the micro particles of dust.

    What you need to realise is that both flow and suction are important. A vac might have huge vacuum (like what you feel if you put your hand over the end) but on its own vacuum is no use - there is no flow. Similarly flow without vacuum isn't so clever - you can't lift anything slightly heavy. Those low power, big bore extractors are fine for light chips from a single machine, but hopeless for anything with any substance, and likewise hopeless for fine dust because the filtration isn't good. For small fixed industrial installations my company generally supplies 7.5kW to 15kW units. It is very unlikely that you will be able to connect 3 machines together on a 550W extractor - these are designed to be connected directly to a single machine. For a diy workshop with more than one attachment point you would be better looking at a 3kW single phase unit with 3 motors in parallel, with decent filtration, and keep the pipework reasonably small - 50mm-ish - any bigger and there won't be enough suction from 3kW to keep the pipe reliably clear.

    Here's 3 "little" units destined for a small fixed installation in a car factory in the UK

    The standard hose is (I think 105mm internal), it's easy to slide it over each machine, when in use.
    Wood dust (H&S E will disagree) - is hardly a big issue, compared to any silica (or paint or MDF) dust.
    For a home workshop, I'd get Lidl one as an addition for routing, hand sanding etc
