Ok, so i bought some new 901 and 510 atomizers online and noticed that they have a different internal design than what I was used to. (see picture). I'm used to the metal mesh being down there, and now i've got this very intersting metal disc. Only thing I can come u with is that they are there to prevent flooding, is this correct? I have noticed they are way tougher to get started (priming) but compared to my more traditional atomizers don't blow through liquid nearly as fast (they don't produce nearly the vapor either). I would like others opinions on this design and if they are made by a specific manufacturer. Would be nice to be able to identify this manufacturer so i can be more proactive about what I purchase in the future. Thanks for any insights!
