Aftermarket dust extraction filters with large surface area - Wynn style replacement

[honza992]

I'll shortly be building a dust extraction built around the Bernardo RV 350 blower:
https://www.bernardo.at/en/rv-350.html
I'll use 6" pipe to as close to the machines as possible, but so far I'm completely failing to find an aftermarket filter like the Wynn but which is available in Europe. The Wynn has got something like 22m2 of filter, several times bigger than the ones sold in europe and is MERV15.

Does anyone know of a Wynn style after-market filter with a large surface area, 20m2 plus, that filters down to at least 0.3micron?

@MikeK I'm sure I read a thread of yours about this, but now i can't find it for some reason. Someone mentioned contacting a norwegian company about filters....but again I can't find the thread.

Any help appreciated!

Thanks Mike, really appreciate it. Any idea how loud the RV350 is? I can't find a decibel rating from Bernardo.

I don't know how loud the RV350 is on its own, but my DC is in a closet. When it is running it is easy to have a normal conversation in the shop without hearing protection. Here is a picture showing the system with the two closet doors open.

Sounds like you certainly need to update the mask. Try something like this Safety Dust Face Cover Reusable Adjustable Full Face Cover Protecting, for Painting, Dust, Particulate, Machine Polishing, Welding and Other Work Protection, with Cottons : Amazon.co.uk: DIY & Tools

THis is such a neat build! Did you ever do a thread on building the dust extraction system?
