Indoor/Outdoor High Temp Low Humidity Environments, 3100 CFM, 950 sq. ft., 3-Speed Fan, 59 dB, Dark Gray
EVAPORATIVE COOLING: HESSAIREs evaporative cooling fans are designed to pull hot, dry air through a water-soaked filter using a fan to decrease the ambient temperature. *It DOES NOT use refrigerants to remove heat & humidity like an air conditioner.
INCREASE HUMIDITY IN DRY CLIMATES: The MC37V evaporative cooling fan is optimal when used in hot, dry climates to filter ambient air while increasing the condensation and delivering 3,100 CFM of cool airflow. *Not effective in high humidity areas. 
ENERGY EFFICENT & ECO FRIENDLY: Evaporative cooling fans save up to 50% on electricity compared to refrigerated air conditioning systems. Using water instead of refrigerant prevents any release of ozone depleting chemicals into the air.
MANUAL & CONTINUOUS WATER FILL: Hessaires MC37V has a 10.3-gallon water tank creating up to 3-4 hours of use. The built-in float valve and garden hose adapter allow for easy connection and continuous water flow without overflowing your tank.
