I've had to downsize my workshop so haven't really got room for a chip extractor and a vac extractor, so I really need a solution that can do both.

My equipment includes a Scheppach P/T, TS4010 table saw, Basato bandsaw and a DIY router table with a 100mm dust collector attached. Power tools include a sliding mitre saw and various sanders.

I've got the Scheppach 1.5hp chip extractor and an early Axminster drum vac

What are my options?

As I mentioned in the other thread, there isn't a one extractor fits all solution.

In terms of options specific to your machines, you could get a smaller 100mm extractor for the table saw and bandsaw, and then use the vac on the rest, or you could look to put your chip extractor outside to free up some space?
 
How big is the P/T and how much shavings do you produce a week?
Some of the HPLV extractors with 100mm connections can actually take quite a few shavings. I had one until year or so ago when I got to the stage that I had to unblock it every 20 minutes but that was on a 400mm planer. They have the advantage that they will step down to 50mm or smaller for power tools.

Never used it for that but was told it would be OK when reduced down.
I'm pretty sure that anything designed to work with 100mm is going to struggle when it gets to a 32mm dust port. I could be wrong though :)
 
Presuming HVLP means high volume low presure and the Yorklean linked to is not low presure. It's high presure and relatively low volume but this does not drop off under load like conventional chip extractors so handles my 310mm P/T OK
 
The wv2000 was the first extractor I bought. I used it to connect to a 300mm thicknesser and 300mm surface planer albeit one at a time.. Its a vacuum extractor so suitable for small power tools and it will cope quite well with chips too but it will clog up if being used on a thicknesser with heavy cuts and backing on board up after another.

Surely you'd need to have a much stronger motor than that to create anything close to high pressure in a 100mm diameter pipe?
 
I have an old one of these: http://www.axminster.co.uk/numatic-nvd1 ... tor-702681 and it did sterling service prior to getting a 2000m3 chip extractor, its not the best at extracting chips for a PT, but good for my Router table, table saw and small tool dust extraction, at 2400watts its brushed motors are noisy.

Forgot to mention the beauty of the Numatic vacuums is the optional use of Hepa filter bags on the small inlet for sanding.

Nope the biggest problem with the WV2 was that if you block the pipe or form a complete vacuum it will try to vacuum press the contents of the bag. I ripped more bags doing this then I care to remember.

You could. My WV2 came standard with a 38 or 40mm pipe and reducer and a full set of floor and crevise tools

Yes I get the same. Very thick cut on something like tulip were you end up with a 300mm wide chip it can get blocked but other than this it's excellent.

Haha. Yes I converted mine to take a metal dustbin but if I accidentally shut the blastgate before turning off the extractor the bin implodes :shock:

It was this problem more than anything that made me convert to a high volume machine for my big chip generators. Now thicknessing and spindle moulding are completely transformed. I do not see dust or shavings. No more stopping every twenty minutes to unblock the mass of shavings on the first bend.

Having to clear it every 20 mins would do my head in but never had much problem myself. Guess you are running big kit. Never had it block when running the spindle and only occasionally on the P/T and even then a good clean of filters usually sorted it.
 
I have never seen the WV 2000 before, I wondered what the 2000 designation was so had a look, can't seem to find anything about it that equates, but the specification does say it has a suction of 125lts/sec that is the equivalent of 450m3/hr which is a more useful comparison to other dust/chip extractors, my Numatic I quoted earlier works at 380m3/hr so pretty close, but it did have trouble clearing all the chips from my PT, this is now doing service as a small tool extractor and floor cleaner, my current chip extractor operates at 2000m3/hr and I have never had to clear anything from the ducts, in fact cats and dogs are discouraged from coming near my workshop. LOL

The hard thing to work out is suction under load. Correct me if I am wrong but I think most machines are rated without load and short suction hose. In reality we end up with more hose, corners, and hoods so they are performing below spec. The regular chip extractors lose vast amounts of suction when resistance is applied. Try putting your hand over the end of the hose and you can feel the reduction from the initial suck to what it becomes ones partially blocked with your hand. The high presure extractors have far less problems with resistance so in the real world the difference in rating between the two types is much less than the figures would suggest. Not suggesting a dedicated chip extractor is not good at it's job. Used to have an Startrite Cyclone and it was great at chip removal but did put a lot of dust back into the air and hopeless if I did get a partial blockage.
 
In my experience what is said consistently on here is correct, the high pressure low volume vacuum's are very efficient at collecting fine sawdust, but are not as efficient when collecting chips from a router or PT, however the high volume low pressure extractors do not have a problem with large chips of timber and when fitted with a pleated paper filter are also more efficient at not spreading fine dust around the workshop, so to my conclusion as everyone else who has experience of both, you need two units, one to extract from your large chip machines (chip extractor HVLP) and another (vacuum unit HPLV) to attach to the fine dust producing tools, also with the Hepa bag installed inside the Numatic the dust is for all intents and purposes is non existent.
