    They are particle sizing cyclones, commonly used in mineral processing (I am a retired metallurgist). They can be used dry as on drill rigs to collect samples from the dust / grit blown up the blast hole by the drill rig, or wet in a slurry to sort coarse from fine particles. They do not work as a vacuum in these applications, but under pressure. The slurry is pumped into the feed inlet on the side of the cyclone - it spins in the top part of the chamber - the heavy material falls and drops out the bottom which is open to atmosphere, while the bulk of the water and the finer particles are pushed out the top discharge pipe. For our application, you would simply connect your vacuum pump to the top (discharge) outlet and a hose to your thicknesses etc to the inlet pipe on the side of the chamber - the dust will drop out the bottom of the cyclone. To regulate the "cut" size (ie how much / how fine the material dropping out the bottom, you simply change the diameter of the spigot (in the bottom) and the vortex finder (in the top) of the cyclone - or you can make the air inside the cyclone spin faster by applying more suction power on the vacuum side. The easiest way to get 'clean air" out of the top is to run the smallest diameter vortex finder you can get away with (without putting excess load on your vacuum pump) and a large spigot - the pressure differential inside the cyclone will push pretty much all the solids out the bottom.

    A simplified diagram of how they work is below -

    No - haven't heard anything from them yet. But that's not unusual where I live. I can import parts for my car from England much faster than from dealers in Australia.

    Mine finally arrived today!, assembly was very easy and straight forward and it works great, only thing is I forgot to buy some 4inch hosing to attach to my equipment!.

    I need some recommendations on what to buy so the dust extractor turns on when I start the table saw or thicknesser?...

    I'm still waiting for them to even acknowledge receipt of my order. I note that they have taken the money from my bank account though.
    Not impressed with Carbatec at all so far - if this is an example of their "service" - they won't be seeing any of my business in the future.

    I feel your frustration, which email have you sent a message to?, have you spoken via the chat feature?. I spoke to Rod if that might help, also spoke to him on the phone.

    If you get no joy, I can flick 'em an email on your behalf. You'll have to send me a PM with your name though.

    All sorted thanks. I spoke with Matt on their 1800 number this morning - it seems that they have two separate accounts for me. One uses an old email which no longer exists, and this is where they sent the email confirming order etc. Matt has confirmed that the dust extractor is in transit, and has merged the two accounts for me so I shouldn't have any further problems.

    I also have another order I have since placed with Carbatec for some other items - this one went on the "new" account which uses current email and I have already received notification from both Carbatec and Australia Post that it is on the way.

    No probs, I had to make a new order myself for the 4" hosing which I forgot to include!

    Mine arrived yesterday. Now to start modifying my system and fitting the new unit in there somewhere.

    Definitely a much more substantial looking machine than anything I have been using to date - should get some good results with it.

    Did yours come on a crate?. I've filled the bag by about 3% so far haha!, it sure as hell does a good job on my tablesaw!. What mods are you making to your system?, I've just ordered the 1micron filter for it.

    Yes - mine arrived on a small half pallet. Not sure that the wood in it is usable though, but will strip down as per any other pallets I get my hands on and put the wood away for later.
    I already have a home made extraction of sorts, that originally started with a normal household vacuum cleaner sucking through a 2 inch cyclone which is mounted above a drum of about 100 liters capacity. I replaced the household vacuum cleaner with a small Sherwood dust extraction unit, only to find that the 2 inch cyclone and hoses was too small and the resultant "whistling" set off all the neighborhood dogs - and was probably not doing my ears any good - though it does work quite well, especially with my home made router table.

    I then bought a couple of 90 degree elbows (4 inch) and mounted them in the lid of a 200 litre drum to give a cyclonic dust collection bin and ran the Sherwood unit through this using 4 inch vacuum hose. It works, but the Sherwood unit does not have enough grunt for it to be really effective. So the plan is to set up the new Carbatec unit plumbed through this 200 litre drum so that the bulk of the dust / woodchip etc drops out into the drum, with only any remaining fine dust collecting in the bag on the Carbatec unit. I already have 4 inch hose, "Y" pieces and blast gates set up between the drum and my table saw, thicknesser and band saw. Will probably set the Sherwood unit up dedicated to the router table and for general floor "vacuum cleaner" applications, which it works quite well at.

    I've also got the feelers out for a slurry sizing cyclone or two from mining surplus / salvage. I am sure that I could easily modify one of these to work very efficiently in a dust collection application, and would probably mount this (and possibly also the Carbatec unit) in a small "lean-to" outside of my shed in the future, as I am starting to get very pushed for room in the shed (it doubles as parking for two cars at night).

    Thats not a workshop its an aladdin's cave!. I'll be interested to see what your system looks like when you've finished. I only have a single car garage and my car can sit on the drive forever and a day. The only thing missing from my dust collection system now is a new shop vac as the 20lt Ryobi one I had just started smoking. Might go for the 60lt unit but undecided yet.

    I assembled the Carbatec unit this afternoon (in between plastering and fitting a new window to the bathroom I'm renovating at the moment). It certainly has plenty of grunt and moves some air.
    But - it will be getting modified VERY soon I think. That useless strap arrangement that holds the plastic bag on the bottom is one of the worst examples of "cheap Chinese RUBBISH" that I've seen in a long time.
    Apart from being awkward to fit (and that's putting it very politely), it is bloody dangerous. I'm on blood thinners and bleed all over the shop on a frequent basis as it is, without messing around with a sharp piece of crap like that thing. I can see this thing being set up to either blow through the 44 gallon drum I have already set up to act as a sort of "cyclone" - or possibly through a hydrocyclone from the mines if I can get my hands on one. Whatever I set up will simply vent to outside my shed - possibly with some sort of dust filter on it.
    For the price though, I'm not complaining. It seems to be a very good motor and blower unit (I'll replace the cheap Stop/Start switch with something decent as I have with all my other fixed equipment in the shed). I'm pretty sure I'll be able to get it working well for my needs - definitely a huge improvement over what I have at the moment.

    The shed was originally a 3 bay large car garage. I used to have a large Ford F100 and could park it in any of the bays and ride a pushbike around it inside that bay. I enclosed one bay and that is now where my portable tools are stored, plus a welding bench with a couple of welders, the pedestal drill, a couple of work benches and an area for both vacuum and pressure resin casting - I play around with epoxy resin a bit and there are some great timbers available locally here that are very amenable to resin casting. In one corner of this enclosed area is a sound insulated cabinet I built from old pallets and some thick foam from Bunnings. My shed compressor lives in here - and the all important beer fridge sits on top of it.

    The other two bays of the shed have gear all round the outside of them, including wood working bench, lathe, saws etc and we park our cars in here at night, so everything is either permanently mounted / stored around the perimeter or is on wheels so that I can move where I need them and put them away quickly at the end of the day.

    The silly thing is that we will probably not be here for that much longer. I've stopped working now - originally for health reasons earlier this year, but now I just can't be bothered any more. Both kids have moved on - one in Perth and the youngest in Bendigo. I have a house with a similar size shed overlooking the water at the entrance to the Derwent River in Hobart, and the plan is to move over there in the not too distant future. Not looking forward to packing the contents of my shed and moving it - but I already know a couple of fellow woodworkers in Tassie - one of them lives in the house over the road from mine.
