The Hessaire MC37V 3,100 CFM Evaporative Cooler is compact in size, pleasing in aesthetics, and the performance exceeds coolers of a much larger size. This performance is achieved through expanding air-intake areas to the high-density rigid media. These coolers have 3 media panels instead of a single panel found on most mobile coolers. 3 panels allow more air-intake area and reduce pre-rotation of the air to the prop, which translates into lower static pressure and more efficient air delivery to the prop.
