Chip & dust extraction

[RichD1]

Hi Guys, having now just built a permanent workshop for all my woodworking equipment I would like to install a fixed dust/chip extraction system. I already have a Scheppach HA 2600 chip extractor and would like to know whether this has enough power to cope. My plan is to have 100mm blast gates on one side of workshop for TS and PT and then on the other side reduced down to 63mm for router, mitre saw, bandsaw etc.

What do you think?

Keep all the pipes large and only reduce diameter at the very last opportunity.
Push fit 110mm drain pipe is generally cheaper than 100mm stuff and you can glue a 100mm blast gate into the open end of 110mm pipe with foaming PU glue to fill the small gap then use shortest possible length of 100mm flexi to the machines.
Use swept branches or 45 degree branch plus 45 degree bend for transition from horizontal to vertical.
Put the machine producing the most waste (P/T) nearest the collector.
Keep the sliding section of all gates horizontal and close the gate before switching off the extractor. This reduces the fine dust getting into the slide of the gates and restricting their movement which leads to leaks/whistles.

Myfordman is this what you mean by a swept branch?

You can use one of those followed by one of these
http://www.toolstation.com/shop/Roofing ... 868/p79259 to achieve a 90 degree branch. The last drop on the run can use just a single 87.5 degree bend

It is what I use for my horizontal drops to each gate/machine

I can't readily find a picture of the large radius swept branch and the above will be nearly as good.

Yes but it needs to provide a branch too. Adding that to a branch will give 135 degrees.

Thanks Guys, I think I've now got enough info to build my system.
