Abstract: The invention relates to a Coanda effect flow booster (10) for inducing a boosted flow of gas, comprising: —a main air circulation pipeline (14), —at least one injection opening that opens into the main pipeline (14), —a plurality of openings for supplying compressed motive gas, each opening configured to be connected to a source of compressed motive gas in order to supply the at least one injection opening with compressed motive gas, —at least one distribution pipeline connecting the plurality of supply openings to the at least one injection opening, —a booster profile (48) at least partially defining the at least one injection opening and forming a convex surface configured to create a Coanda effect in a flow of compressed motive gas injected through the at least one injection opening.

Abstract: The invention concerns an air-moving device (10) for pollinating at least one recipient plant using pollen collected on at least one donor plant, comprising: a means (12) for collecting pollen from said at least one donor plant, a means (14) for distributing pollen on at least one recipient plant, a channel for conveying the pollen collected from the collecting means (12) to the distributing means (14), an air flow amplifier (18) which employs Coanda effect for inducing a flow of air inside the conveying channel (16) from the means (12) for collecting the pollen to the means (14) for distributing the pollen. The invention also concerns a pneumatic deflector for deflecting the Coanda effect flow of pollen disposed at the level of the pollen distributing means (14).
