PROVISION APPLIED TO EIGHT BLADE PROPELLERS FOR FAN.

摘要

consists of a propeller (1) for a domestic fan (2) whose blade (3) has a geometric / functional and aesthetic synchrony, with a thin profile and less curved with a more uniform thickness from the central hub (4), which allowed for positioning eight blades (3) in one propeller (1), resulting in a fan (2) more efficient in generating air flow (flow) with a lower speed (rotation) and with a less powerful engine, obviously with less generation noise and more comfort for the user.
