Not got space for 2 machines in van so I'm after a duel purpose vac and dust extractor possibly L class, just tried a mates festool midi for the day and blocked it up with chippings, great for dust but not as a site vac, can anyone recommend a duel purpose vacuum with power take off
Site vacuum/ dust extractor all in one needed

Nilfisk (KEW) are excellent machines and the large ones are built for commercial use. Expect to pay top dollar though, and Machine Mart have them on display.

If you are dealing with timber products you will need an M-class extractor. Same goes for concrete dust as far as I'm aware. This is now law - so no longer an option.
To handle chippings such as you get from a planer you will need a large enough bag and a large enough hose. A 35mm hose should be your minimum, although 50mm is better, and whilst a 25 litre machine is acceptable, a 35 litre machine will have just that bit more run time. I have a 25 litre M-class Metabo (Starmix) which can cope with a Bosch GHO40-82C planer on a 35mm diameter hose, but it needs to be emptied regularly. I've decided that my next vacuum will be a 35 litre Starmix (Metabo ASR35M or similar - not cheap) and I'll be availing myself of the larger 50mm hose as well as an option. Sorry to say it but tools like the Midi have had their day in commercial work where the standards have now overtaken them

Looking no larger than 25litr really, plus don't do site work any more so should get away with a l class with m class filter as only in domestic that's why I need a duel purpose vac extractor I know it's not perfect but that's what I need

In that case look for a vacuum which will accommodate M-class filters and a 5omm hose. I know that Starmix (also sold badged as Metabo, Spit, etc) and the larger Festools (CTL, etc) will do this
I have the Festool CTL 26AC. It shares the same filter system as the CTM 26.
Basically, in terms of the level of extraction, there is no difference between the CTL and CTM extractors. They both have the same motors, same filters, same bags. Both are equally good for wood dust extraction.
The only difference is that the CTM has a sensor & circuitry that provides a warning if the airflow through the inlet falls below a certain level. You only need that if, for some reason, you need to absolutely guarantee that the suction doesn't drop off (due to a full bag, blockage etc) without you knowing about it. Chances are, even without that warning, you'd know if there was a problem!
The CTL is approved for dust category L; the CTM is approved for dust category M. Having the warning sensor is, presumably, a pre-requisite for approval for category M, but since the components are the same the CTL must therefore also be suitable for dust category M, it just can't be approved for it.
That's my understanding of it anyway.

Yes. In terms of the running costs it's the bags which are the real killer. For some models like the Bosch GAS25 bd Metabo ASR2025 you can get recycleable filter bags off Amazon which will do quite a few fills before they expire. Watch out for stuff like soot - it's greasy and can bugger up a pair of filters in next to no time, even the washable polyester class M ones (and at £65 a set for mine that's not funny)
4 bags 7.99 or paper ones around a quid each is best I've seem so far
Festool was one i was looking at but the one I borrowed kept clogging pipe when I used it to vac up slightly larger stuff
