Blowers, e.g., for use in outdoor applications, are provided. A blower includes an air inlet; an air outlet; and a fan assembly disposed between the air inlet and the air outlet. The fan assembly has a three-stage fan. The three-stage fan includes three axial fans mounted on a drive shaft and three stator fans arranged in series with the axial fans, wherein each axial fan comprises a plurality of blades each having a blade tip. The three-stage fan has a dimensionless flow coefficient Φ in a range from about 0.3 to 0.5 as calculated by the equation Φ=(q/(A))/ωR where q represents flow (m/s), A represents cross sectional area at the fan (m), ω represents speed (rad/s) and R represents fan tip radius (m) measured at a blade tip.
