This is the current replacement motor for PolarCool 36" variable speed evaporative coolers, including standard, Pro, and Zone 11K models. If your fan runs slow, hums, or won't start, this Vosterman 1/2 HP motor restores airflow without replacing the whole unit.
This motor is built for the 36" variable speed line of PolarCool evaporative coolers, where consistent airflow control depends on a reliable 8-pole variable speed motor. It's the current production motor across all 36" models, which means one part number covers standard, Pro, and Zone versions rather than tracking separate legacy SKUs. 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.
