A blower assembly includes a fan including a front plate that defines a fan inlet. The blower assembly also includes an inlet plate positioned adjacent the fan such that the inlet plate and the front plate define a cavity therebetween that extends circumferentially about the fan inlet. A motor is coupled to the fan and to the inlet plate and configured to rotate about the rotational axis. The motor is positioned within the cavity.

There is provided a nozzle for a fan assembly. The nozzle comprises an air inlet, a first air outlet and a second air outlet that are oriented in convergent directions, and a valve for controlling the first and second air outlets. The valve comprises one or more valve members that are moveable to simultaneously adjust the size of the first air outlet and inversely adjust the size of the second air outlet. The nozzle further comprises a third air outlet and a fourth air outlet, the third air outlet being opposite the fourth air outlet, the third and fourth air outlets being oriented in convergent directions, and the third air outlet and the fourth air outlet each being substantially perpendicular to each of the first and second air outlets.

A fan for a climate control outdoor unit includes a plurality of airfoils located around a central hub. Each of the airfoils includes a leading edge and a trailing edge opposite the leading edge. A pressure side surface extends between the leading edge and the trailing edge. A suction side surface is opposite the pressure side surface and extends between the leading edge and the trailing edge. The leading edge includes a greatest negative deviation from a radial line of greater than 10% of a span of the airfoil. The greatest negative deviation is located at between 45% and 85% of the span of the airfoil.
