Unlike the classic ''[[sleeve filler]]'' the ''aerometric'' filler however provides for the presence of a breather inside the system, which requires to repeat the pressure of the bar four or five times (as shown on the instructions engraved on some of them) to complete the loading. It can therefore be interpreted as a fusion between a ''[[sleeve filler]]'' and the previous ''[[vacumatic filler]]''.

The name ''aerometric'' is actually used in this sense mostly by collectors, the company was rather referring to it by the name ''[[Aero-metric Ink System]]'' (reported for example in advertisements like [[:File:1950-Parker-51-Signet.jpg|this]]) for the set of the filling system (called ''[[Foto-fill filler]]''), the feeder and the new PVC tank (called ''[[Pli-glass]]''), which allowed the company to proclaim the pen as not containing any rubber parts.<noinclude>
