I think if you're ok with a big unit, I agree with kraftt . Maybe even the S36 for the extra oomph (but it weighs 20kg more!). I like my Mafell S35 HEPA (Starmix mentioned by aas ) well enough (ok, I like it a bunch and it's swell, but if I was doing more grinding I'd go for the S26/36).
I looked at the S26/36 pretty hard, but the size of it made me shy away. Portability was a big sell for me as I don't do that many jobs lasting more than a day or so. I'm a HUGE fan of the longopack concept and not having to touch the dust once it's been gathered. That unit also has a duct port to route your exhaust outside the protected space (makes for one less thing stirring dust up in your work area that you'll need to clean later), which is a really nice feature. I don't see that much on other units as a standard feature. The Starmix has an accessory you can buy (if you can find it) to do that, as do Nilfisk's Attix series, but not many others. The Oneida ducts their exhaust out the top via a dispersion baffle, so it's not blowing air around on the ground, but it's still blowing air around in your work area.
Another unit to toss in there if you're doing a lot of grinding is the Oneida CC500 (maybe with a pre-separator, too). It's a fully packaged system that folds down specifically to fit into a van; the Husqvarna doesn't do that (fold down), to my knowledge. Husqvarna do sell pre-separators, as do Oneida. For the filter arrangement, I'd probably go with the Husqvarna, as it has a two stage filter arrangement to prolong the filter; though the Onieda with the cleaning system supposedly has similar filter replacement schedules.
For grinding (and general collection), you might seriously consider a metal pre-separator to go on the front of your chosen vacuum. Two stage cyclone separation is considerably more efficient for small particles, but not really needed for larger particles; several studies I read while going all the way down the rabbit hole showed 15-30% improved efficiency for a second stage. 3 stages starts to significantly impact flow rate while not significantly improving separation efficiency.
I'm working on a similar concept to fit in a Dust Deputy/cyclone separator, with the added condition of having the bag always reside in a bucket / drum to eliminate my stupid self from cutting the bag while dragging the assembly around; similar in concept to the Ermator S1400, but more portable.
Filtration, and electronic monitoring. The H Class filters are H-14, the M Class (If I correctly understand) have poly filters vs the HEPA filtration filters on the M. The H model also has more electronic monitoring for the thing and alarms. aas can speak to the alarms, mine doesn't have them (being in NA, we scoff at such monitoring or safety requirements...).
Yep, very annoying alarm, I opened up the vac and unplugged the beeper, so just the red light flashes.
Mine came with the systainer rails, the CT-VA clips on top. I have the 35mm Starmix hose, I removed the Starmix bayonnet fitting and fitted the Festool angle fitting that came with the CT-VA - it is also the right size to plug straight into the vac, so I can use with or without the seperator.

I just bought a Metabo branded Starmix. Mine was an older model: ASC 50 M SC. I liked the larger (50L) capacity, for fluids & planer & router (high volume) swarf & shavings. The wider, more stable footprint better suits my tall Oneida Ultimate Dust Deputy or Systainer stack on top, the big manoeuvring handle & longer (4M) hose. I also absolutely LOVE the onboard accessory rack for floor tools, pipes etc.
The fact that (as old/er stock) it was actually less than half the price of the latest Starmixes & Fuss-tools was pretty compelling too.
I actually do quite a bit of concrete cutting, occasional grinding & a whole lot of chipping, chasing & demo. It still has the (albeit less sophisticated) automated self-cleaning filter function of the contemporary Starmixes & their branded clones. Plus the requisite airflow sensor/alarm for safety.
My biggest gripe so far is that @ 1400W I feel it's a bit too powerful for most of my basic sanding & cutting functions, & that it has a pretty lightweight, rather shitty plastic power cable rather than the heavy duty rubberised lovely flexible cable of my old Fuss-tool CT22. When connected to my Metabo Sawbench (2200W) or DeWalt-equipped Router Table (2300W) that's an awful lot of current (up to 15 Amperes) to be pushing through such an insubstantial plastic cable.
With an unlimited budget, I think I'd have preferred the Starmix iPulse H-1235 Asbest Safe Plus machine. It's 1200W max power level allows plenty of "safe" headroom for conecting even more powerful saws & routers whilst still offering more than ample levels of vacuum & suction for even the most heavy duty applications.
The other iPulse & clones' power levels of 1600W output is in my opinion ridiculously excessive & unnecessary. It may also be potentially dangerous to have this much pressure in the vac's bodywork potentially aerosolising hazardous dusts & fibre. The "Asbest Safe" model's limited power offers the maximum operator protection available in the industry against all those deadly cement silicates & blue asbestos fibres one occasionally encounters in renovation work.
abdon: I stand corrected , the angle fence is only attaches with F -Tracks , what confused me was , that the Timberwolf site mentioned it will work with the NFU machine, yes it will work but only I guess when you use the Ftrack , with other tracks Like the KSS L.

glynnco: Did you order from GereedschapPro? I see them as in stock but I'm located in the US and am not sure if they ship here. I sent them an email asking about shipping but it was returned undeliverable...

jonathan: I've purchased a lot of stuff from our neighbours @ GereedschapPro.nl As far as I know they are one of the larger Mafell dealers in the EU. I can recommend them, they usually respond quickly.

lasse: Thanks for the tip! I have own a mafell rail which is 160 cm and one that is 80 cm. Will it work just as well or will I need to buy rail that is 110 cm?
