Dust extractor upgrade?

[RorieT]

Hi folks,

I am away to install 110mm drainage ducting system around my workshop (i expect the longest leg to be around 10m). I currently have this dust extractor:

I was looking to add on a cyclone unit like this

But then i saw, for the same money (close enough anyway) as my current extractor, i could buy one of these:

The chip extractor has has a flow of 800m3/h in comparison to my current extractor which is just 183m³/h. I assume from this that the rutlands extractor will be much more suited for my new set up? But why is there such a small price difference for such a massive performance difference (other than the fact its on sale of course!). Am i missing something?

I am assuming that my current extractor will not be up for the job, but can anybody advise otherwise?

The chip extractor is only needed for planers really. Better off having everything else close to the machine your using and plenty of suck as its only dust.

I've been through the same dilemmas myself over and over and coming to the conclusion its better to have a dedicated chip extractor for planer thicknesser and for everything else just use things like wickes vacs or better (or that sip thing) preferably with a cyclone.

Ah ok, i didn't realise the chip extractor was more for chips than dust.

So i guess the best thing is to add one of the cyclones to my SIP and hopefully there will be enough suck!

Hmmm, I could be wrong here and I'll be happy to stand corrected but.....
I've been reading up a little on these things. The Rutland chip extractor has a much greater air flow rate. That doesn't necessarily mean it will create a greater pressure, but chances are it will. If it's moving much more air, it should have the ability to move more dust.
If you wanted to, you could make it into a two stage using a drum and cyclone before the main unit, that should help with dust and reduce the frequency for emptying the bag.
Personally, I would be going for the Rutland, good price too.

m3 per hour become meaningless under load. Used to have a chip type extractor but the flow rate drops off quickly with resistance that 10m of ducting will probably create. Now use one of these http://www.yorkleen.co.uk/documents/pro ... =1&subcat= It is much the same principle as your Toolstation machine and is more than capable of clearing all the chips from my 12" planer thicknesser but is also good with long runs and fine filtration for bandsaws etc. Not knocking the chip type extractor as a dedicated machine on a PT but for a ducted system it's unlikely to have enough suck.

2.4kw helps!

I've been searching and searching for a good deal on a 2-3hp dust collector but they are all too expensive for me at the moment

I've got a 750w axminster chip collector and it will just about do the planer thicknesser but struggles if anything is further away so I use a a SIP thing too.

Sorry yes sure it does. Was just trying to point out the different styles of the two types of machines but like to keep my points to personal experience. Mark Hits the nail on the head when he talks about presure. Pressure will cope with restrictions and long runs whereas the chip extractor requires free flowing air to perform and will produce very little presure.

Another option is to build your own snail type fan.
