Pneumatic conveyor for empty, lightweight bottles (1) of the kind incorporating a support flange (2) at an area of their neck (3). Said conveyor comprises a pair of coplanar, spaced apart supporting tracks (5) for supporting said flange (2), a pair of upper guiding tracks (11) opposed to tracks (5), and two bodies (12) arranged therebetween. Bodies (12) comprise passageways (13) communicating at one end with at least a pressurizable chamber (7) and defining at the other end blowing nozzles (6) which expel thrust air jets against the zone of the flange (2) of the bottles (1). The pressurizable chamber (7) is formed by a wrapping (8) easy to dismount, of a flexible and airtight material, such as a tarpaulin. The upper tracks (11) and bodies (12) are joined to the structure (4) by rigid means, while the tracks (5) are joined by elastic means allowing to manually withdraw the clogged bottles (1). Obturating plates serve for regulating the air flow through passageways (13).
