The JCB EAC 30J is the larger of the two evaporative air coolers, delivering 30,000 CMH of fresh, filtered, and cooled air through a UV-treated polypropylene body. Powered by an Ecoair PMSM motor at 2.2 kW, it can reduce ambient temperature by up to 20°C while consuming up to 80% less energy than conventional air conditioning. The cooler supports side, top, or bottom discharge and connects to ducted distribution systems via its 777 × 777 mm duct opening. It is suitable for large industrial halls, factories, and warehouses where fresh-air cooling is preferred over recirculated refrigerant-based systems.
