Hi @Jan and @ForbiddenTuna , i been had an awful lot of things going on last weeks, but its back in normal order now 
Cody’s right, it is 200 mesh, i wanted 400 but that wasn’t available in 10 meter lenght.
The volvo filter is probably 400 mesh, very fine.
Jan, I’ve had some missed calls from Jonas, and then i tried call him, and so on… i think im going to call him tomorrow, for some woodgas-talk
