JARO Thermal's new JDA series of AC fans optimizes temperature by intelligently sensing and regulating RPM (revolutions per minute). Thus, as power inputs fluctuate, the fan automatically compensates by decreasing or increasing the fan output (cubic feet per minute). The result is a significant reduction in power consumption, noise and overall cost. The datasheets for these unique, application-specific products can be found here.
