Ventilar Portable Evaporative Cooling technology circulates water around a cooling media pad that cools down air as it passes through it. Water is stored in a water tank within the housing cabinet and can be changed easily through the fan’s water management system. The cooling effect works especially well on hot and dry days where the cooling media can produce air that is up to 10 degrees cooler than the surrounding air. The FSU-24 Model produces 12,000 CMH and throws air up to 20 meters away while the FSU-36 model produces 21,500 CMH that has a reach of 25 meters away.
