Industry Air Cooler

​The Portable Evaporative Air Cooling Fan with Universal Pulley, manufactured by China supplier Jianhui Electrical, is a mobile evaporative cooling unit designed for open or semi‑open spaces of 50–100 m². Employing wet‑pad evaporation with optional ice‑crystal auxiliary cooling, it delivers an outlet temperature 5–8 °C below ambient. Its acquisition cost is one‑tenth that of a central air‑conditioning system, and its service life is 5–8 years with routine maintenance limited to filter cleaning.
