The Eolo air conveyors are single chamber plenums of square cross-section, supporting a bottle channel lower face. The plenum cross sectional area is great enough such that air velocity within the chamber is close to zero. Thus, the static air pressure exhibits almost no loss along the air conveyor length. Local air pressure spikes near fan ports are eliminated by the use of short horizontal baffles at the blower mouths. For cleaning purposes the plenum segments feature bolt-on inspection covers every meter ca. The covers are airtight sealed with rubber gaskets.

Empty PET bottles hang from their neck rings on two parallel rails in the omega conveyor section. Air from the plenum is directed onto the bottles’ finish with a forward-facing vector from jet openings placed at regular intervals along the omega’s internal walls. This air jet is sufficient for accelerating all bottle sizes at speeds from 0m/s to 4m/s ca. in level conveyor sections, as well as for pushing bottles up maximum 10° inclines. Air conveyor lengths are divided into independent segments of not more than 10 meters; vertical end plates seal one segment’s air plenum from the abutting segment’s plenum.
