Big Ass Fans Cool-Space 500 portable evaporative swamp cooler — 50-inch diameter fan for indoor or outdoor use, continuous or 64-gallon fillable capacity, variable speed.
Big Ass Fans has been engineering air-movement equipment in Lexington, Kentucky since 1999, starting with industrial-grade Powerfoil ceiling fans for warehouses and factories and expanding into the residential smart-fan category with the Haiku line. The brand’s design philosophy emphasizes airflow efficiency per watt — Haiku fans use roughly two-thirds less energy than conventional ceiling fans at equivalent airflow.
This model is built around an aluminum hub, balanced blades, and a brushless DC motor that’s effectively silent at low speeds. WiFi integration enables app-based control plus voice control via Alexa and Google Home; lighting models include 2700K dimmable warm-white LEDs with multiple brightness presets.
Made in the USA by Big Ass Fans at the Lexington facility — the same factory that builds Powerfoil industrial fans for U.S. warehouses, gymnasiums, and aircraft hangars. Installation requires a standard ceiling junction box; Coastal models require outdoor-rated electrical.
