This is a replacement 24" fan propeller for older PolarCool evaporative coolers — the 4-blade red fiberglass fan that pushes air through the cooler cabinet. It's built for facilities managers and service techs replacing a cracked or worn blade on legacy PolarCool 24" units made before 2014.
Field-replacement fiberglass propellers like this one are a standard maintenance item for facilities running legacy PolarCool 24" evaporative coolers. Fiberglass blade construction holds up well against the constant moisture exposure inherent to swamp cooler operation, resisting the corrosion and delamination that can affect lower-grade plastic blades over time. This is a direct-fit replacement part — no modification needed when the motor and model year match.
