Abstract
A fan guard for a condenser unit of an air conditioner which supports the fan motor made of wire formed into a plurality of concentric rings or rectangles, or a spiral, secured to a spaced plurality of first radially-oriented elements each having at its peripherally-positioned end an orifice for fastening the guard to the unit and to an interspaced plurality of second radially-oriented elements each having at its end, closest to the fan guard's center, an orifice for fastening the motor to the guard, a third element extending all across the guard, and a sturdy ring affixed to at least the first and second elements proximate to the center. The guard preferably is convex whose wire elements have an elongated cross-sectional shape with lower airflow resistance. The fan guard has low fabrication and materials costs and allows use of motors with lower energy consumption for the same airflow efficiency.
