Leading edge of a fan blade

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.
