This is a replacement swivel wheel for your PolarCool 36" Pro portable evaporative cooler. If your Pro cooler is hard to push, wobbles, or has a flat-spotted wheel, this solid rubber caster restores mobility without the risk of a flat tire.
This caster is a genuine PolarCool component built specifically for the 36" Pro chassis, not a universal or generic wheel. Solid rubber construction means no air pressure to maintain and no flat-tire downtime, which matters for coolers that get repositioned daily on job sites or in warehouses. Note: If you would like to review the manufacturer Product Specifications, Warranty, Brochure, etc., for this system, please refer to the "Resources (System Manuals and Warranty)" Tab above on this page.
