This is a replacement caster kit for PolarCool 36" and 48" evaporative cooling fans, giving you four new wheels — two swivel, two rigid — to restore mobility when the originals wear out or go flat.
PolarCool built this wheel kit for the 36" and 48" evaporative cooling fan line, and it's a straightforward fix when the factory casters flatten out or seize up from years of shop or yard use. Solid rubber construction means no air-filled tires to puncture, so you get consistent rolling performance whether the fan lives indoors or gets rolled around a job site.
