Power Breezer E-Class Evaporative Coolers are heavy duty, industrial strength cooling systems which use water and cooling media (cardboard pads) to cool the people around it. Businesses, including logistics centers, stadiums and event venues, and the U.S. Military use Power Breezer cooling systems to protect people where they need it most. Attractive compact design Wheeled units with integrated water tank for multiple applications Long uninterrupted running time without need of water refilling Ionizer Centrifugal fan Automatic water supply Eco-friendly: no compressor, no gas, very low consumption 8.2 foot grounded power cord 3 year limited warranty Cost-Effective Powerful Cooling Capable of reducing air temperature significantly. In optimal conditions (hot and dry), these coolers can lower air temperatures by 15 to 20 degrees Fahrenheit. This makes them highly effective for personal (spot) cooling or cooling smaller spaces, providing a refreshing environment. Mobile/Portable Design Power Breezer E-Class evaporative coolers can be easily moved from one room to another, providing flexible cooling solutions without the need for permanent installation. This makes them ideal for homes, offices, warehouses, workshops, and outdoor spaces where temporary or spot cooling is needed. Energy Efficient Our mobile evaporative coolers consume significantly less electricity compared to traditional air conditioning systems. This can lead to substantial savings in energy bills, especially in areas where cooling needs are high but the humidity is low.
