Camvac twin motor Vs Numatic NVD750-2 For Planer Thicknesser

[bp122]

I'm in the process of acquiring a Planer Thicknesser at the moment, but when I had sold my old P/T a few months ago, I had also sold my large extractor.
The required airflow as per the website is 1000 m³/hr.

Reading up a lot on the subject of small compact extractors I was looking at the Sip wall mounted cartridged extractor like this one for £308:

(airflow of 850 m³/hr, 2 HP)

But also came across the Camvac twin motor option:

And the Numatic NVD 750-2:

Many of the threads I have read on the forum seem to suggest that the Twin motor camvac styled ones, despite being the HPLV type, handle the Planer Thicknesser chips well and also is more compact and a better overall extractor. So wondered if anyone here has the NVD 750-2 as well, as on paper it has slightly more powerful motors but the mentioned airflow is slightly better on the Camvac.

The P/T will be used most of the time without utilizing the full width and only occasionally pushing full width workpieces. Do these higher capacity HPLV work for that or am I better off getting the wall mounted SIP HVLP type?

I do have a smaller shopvac with a cyclone for smaller things like sanders, domino etc so I don't need the Camvac for that purpose (althoiugh would be lovely to combine and simplify)

Thanks in advance

Personal view....
A 2 motor vac doesn't make enough airflow for a PT.
It doesn't matter how wide the stock is, the air leakage around the block is the same and the 2 motor ones don't move enough air.
I am open to the idea that a 3 motor model might, because hvlp bag types nearly always underperform in practice because ducts are not wide/smooth/ short enough and they may well end up little better than a 3 motor camvac.

2 motor canister vacs are well matched to a 50mm hose.
Planers typically extract through a 100mm or bigger outlet, that's 4x the area. Not a good match.
I have tried an nvd750 on a 10x8 planer thicknesser and it was inadequate. A 2 motor camvac would be too.

Between the nvd750 and the camvac, they both use a pair of generic single stage vacuum cleaner motors. Numatic historically bought good quality panasonic motors. Camvac I don't know. But I expect the motors to have similar performance.
Numatic have a 2 layers of fabric filter across the top of their drum, the red and the white, with a weight that acts to slightly shake the filter when suction turns off. A bag can be used in the drum too for extra filtering.
Camvac use a pleated filter in front of each motor, then put bags over these to stop the pleats getting full of crud and blocking up (a massive design flaw of most cheap shop vacs).
I think the numatic filter arrangement is more intelligent but numatic 3 motor models are only in their more expensive industrial / commercial line up and the 3 motor camvac probably cheaper.

Can't comment on your exact models, but over the years I have had versions of each of these. Other than the initial diy contraptions I tried, I had a HVLP oldish dewalt floor standing version, similar to the SIP, but bag no cartridge filter.
Positives, relatively quiet, large capacity, bullet proof steel impeller. Great on planer/thicknesses. Negatives, not good on much else that makes more dust than chips. Not on a ducted system, always on flexi hoses, these greatly impact their efficiency, takes lot of space in small shop.

Had a yorkleen 150, like the numatic. Single motor. Positives, simple to use and empty, good on chips and dust, Negatives, limited capacity, needs frequent emptying, flters clog quickly with dust from sanding reducing suction quickly. Neither excessive noise nor quiet, just an uncomfortable pitch to me.

Camvac twin motor. Been the best all-rounder, great filtration, noise with silencer tubes ok, choice of one or to motors running is good. Using ros with full power is hard, it sucks the ros onto to wood, using single motor makes it a breeze. Negatives, filters quick to block wiyhfine dust, motors take up lt of space in the bin reducing capacity, need large bin model.

So currently, Dewalt long gone, I don't do much flatwork, not suited to hobby work for me. My planer only used infrequently.
5he Yorkleen is always hooked up to a hobby cnc, Ideal setup for this.
My twin camvac handles everything else. BUT, I have it combined with 4" cyclone and larger collection bin. Short fixed 100mm pipe to lathe and a tee off to 50mm flex for other tools, swap the 100mm over fro lathe to flexi for my 10" planer thicknesses and camvac works fine for that, but the flex run is only 2m max fir it.

Find this setup suits me and the bits I make, but I am only a hobby/craft maker and don't do flatwork.

So I suppose my only advice would be, know what sort of work you will mainly do, lots of chips made, I'd lean to the sip, lots of sanding then the numatic type with a high filtration classification. Mixture of many crafts then the Camvac. Also if you have a machine that can be left running while you get on with other stuff it's handy to have a dedicated extractor, like my CNC

I started out using a Henry hoover but that blew up quickly as the dust was too fine and got in the motor, I then got my twin motor canister and apart from it being very loud it's plenty capable of servicing the bandsaw and the lathe (not at the same time) only downside is if I use both motors with the 50mm hose for too long it overheats and shuts down for a while.
