The Hessaire 1,300 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 hi-density XeL50 rigid media. The hi-density XeL50 media provides 80% more evaporation surface compared to regular density media for higher evaporation efficiency/cooler temperatures. Patented axial prop is energy efficient and throws cool air farther. Molded with ABS resin, creating a strong, yet lightweight design. These coolers have 3 media panels instead of a single panel found on most mobile coolers. The 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. This model features a handle, allowing you to easily carry anywhere. Note: This unit is not an air conditioner and therefore uses much less energy and saves on electricity costs. It is best used in dry climates or open spaces. Leave window/door open to limit the rise of humidity and keep better air ventilation in the room.
