dust extraction

[MazdaMan]

I have just built myself a workshop measuring 18'x10' I am now in the process of sorting out my machinery I am in desperate need of advice regarding the old problem of dust extraction, I have a Scheppach HA3200, which I bought from auction, my problem is the following

1. hose reduction sizes(it looks like a 6"outlet)
2. Can I reduce the pipework for router, sander etc. without losing suction
3. where can I get the parts I need as I have searched the net without success
4. Is this machine suitable for chippings only requiring a further machine for dust.

I may not have made myself very clear but hopefully joining this forum will lead me in the right direction

Hi
I am going to leave others to answer your questions as I have not come across 6 inch extractors.
I just wanted to say welcome to the forum.

Hi there

Have a look at ductstore.co.uk.

They do reducers etc.

Personally I would increase the outlet at the machine ie run 6" pipe to the machine then have a reducing coupler attached to machine.

Blast gates are a must also

Many thanks for the welcome Graham, hope to make use of this very informative site.

Thank you for the response, I have remeasured the pipe, it is 1450mm external diameter, I am also interested in finding out more about the machine as I did buy it blind with no manual or filter bag, yes I should have known better, but I thought Scheppach were a fairly decent make. I have searched the web and keep coming to a dead end, almost to the point of biting the bullet and buying something more 'mainstream', any ideas gratefully received

Dust extractor bags are easy enough to get.
I got mine from here.... http://www.dustspares.co.uk/Extractor-Bags

The images of your machine on google show it to look very similar to most machines.

If it makes life easier, you could always get a 6" - 4" reducer to attach to the inlet. That way piping would be cheaper and easier to come by.

As said above, run the 4" pipe as close to the machine as possible before reducing it to 50/63mm or whatever the machine takes.
Use sweeping bends where possible to maintain flow.

Thank you benjimano, that link looks very useful, it's the filter I need to get, and then sort out the pipework, I am hoping that it will cope with both chippings and dust, just need to get my head round pipework sizes, hopefully now I am on the right track!!!

Hi Mazdaman,
I'm no expert and am currently trying to sort out the dust issues in my workshop. However as I understand it, these types of collector are not really dust extractors - just chippings, and they let the fine dust through and spread it around the shop which makes things worse. I think you would be safer by getting a fine dust extractor, drum type, and apparently they are very noisy (may be an issue with neighbours?)

I have a chip extractor (kity) which I leave connected to my planer / thicknesser. I intend to fit it via a blast gate to my spindle moulder - also kity. For my table saw I have an Axminster wall mounted kit, 63mm diameter piping (no longer stocked) and it's not really up to the job. The filtration is down to 1 micron according to the blurb.

What I have recently done is to get a 12" industrial fan from ebay (about £50) which I plan to place in a panel in front of an open window, and shall link to my lathes via ducting. I don't yet know how well it will work, but I did try some initial lathe sanding on monday. I put an 8" extractor fan to blow the dust towards the window, and switched on both fans. I applied the sandpaper, and I couldn't detect any dust in my nose or mouth. I could see it being taken out of the window, so it seems to work even without ducting.

Finally I have bought two recirculating air filters, yet to be installed, and I hope this will be an effective solution, although I'm not yet sure what to do with my table saw. At least I feel I'm doing more or less what I can without spending silly money.

Certainly I would not rely on just the kity extractor for anything finer than chips.

Thanks for the info guys, I went to a local builders merchant today and looked at the soil pipe range( I need to get out more!!), managed to find a rubber reducer which with some struggling fits the suction pipe on the Scheppach and fits onto 110mm soil pipe(100mm internal) so with a 37deg joint I can run some 100mm pipe, although I now have to work out how to fit that to some 100mm flexi pipe, at least I'm getting there. I will also try to bore you all with some photo's of my workshop which I am rather proud of having built it from scratch, so watch this space ;-)))
