There is quite a lot more to it than you suggest.
To be clear the drimaster isn’t one of my products, so reducing sales will have little impact on my plans for global domination.
But to play along let’s have a look at some of your issues.
You say 50l/s is easy to achieve with an in-line fan. It really isn’t. You need to consider static pressure for a start. 50l/s at free air? Maybe with a filter and duct? Not so easy.
What type of fan are you going to use? Axial or centrifugal? What type of blade? Forward or backward curved?
What filters are you going to use? How are you going to make them easy to replace?
And then you need to consider noise and vibration...
I can see that having a fan in the roof space is a really good idea, it's going to be relatively warm and dry up there and the air introduced into the main house would be warmer and dryer than air brought directly from outside. Also having the fan in the loft will muffle a lot of the noise the fan may produce.To be clear the drimaster isn’t one of my products, so reducing sales will have little impact on my plans for global domination.

I don't have a loft in my house so I'm thinking a Flatmaster is my only option. It'll bring air in through a hole in the wall and positively ventilate my house.
Plan B would to be to buy one of these.

Similar noise level to the Flatmaster at 22 db/3m. Plenty enough pressure at 61 l/s... a bit difficult to filter but then what are we actually filtering ?
Just thinking out loud.
61 l/s is a flow, not pressure.
The acoustic data quoted on the website is dBA @ 3m, so is the noise breaking out of the fan casing as opposed to the noise that comes out of whatever method you choose to distribute it to the dwelling.
You filter the air for the same reason you use any filter. To remove the crap and improve air quality.

So the Ventaxia moves more air more quietly.
I'd be very surprised at that. From reading the thread these Nuaire PIV's are near inaudible in use but you couldn't possibly say that about the exhaust port of a 100mm extractor fan no matter how 'quiet' it might claim to be. I don't think I'd want such a thing running 24/7 in my house?Edit: According to the full specs the noise rating for the exhaust port on the Vent Axia is actually 27/34dBA (low/high speed) @ 3m. The 22dB is just what leaks out of the side.

Aside from the filtration what does the Flatmaster do that the Ventaxia doesn't ?
Yup you’ve 100% got it. You should definitely buy that fan.Aside from the filtration what does the Flatmaster do that the Ventaxia doesn't ?
This thread has a number of accounts from members that have one installed. Unless I’ve missed something there have been no negative reviews. If this independent testimony fails to persuade you I have no chance.
That said; I would be happy to answer any questions you have about Nuaire products.

We have one of these, the heat, and it was great, however we have had to turn it off, the loft in my 1700's cottage is a bit stagnant and smelly!
Anyone else had a similar issue and have any tips?
Soffit vents probably weren’t a thing back then...Anyone else had a similar issue and have any tips?
You might want to look at a 365 as that has a ducted fresh air inlet as well.

How long did you try it for?Anyone else had a similar issue and have any tips?
We too had a smelly loft, and that aroma was then ducted into our house...but after time the aroma disappeared. Maybe 4 - 6 weeks.
Plus all the other household smells dissipate quite quickly too.
What I need now is a pair of spare filter bags for a quick swap. Do they sell them separately?

Exactly my experience and yes they sell the filters separately. Just changed mine after approx 5 yearsWe too had a smelly loft, and that aroma was then ducted into our house...but after time the aroma disappeared. Maybe 4 - 6 weeks.
