Hello David!
Thank you. Yes, speed is a rather low but I have absolutely no clue of how strong the vacuum must be, I tested each part of the air system and the weakest point seems to be the valve unit. Most of the vacuum is lost at the valve. Perpahs I will sand it down and polish the surfaces... We will see.
Kind regards
Frank
