This heavy-duty mister covers 800 square feet and is designed for both home and light commercial use. The MF24B is a centrifugal misting system that creates a dry mist to keep you cool during hot weather. The non-clogging misting plate and powerful pump work together to produce a temperature drop of 30? - 45?F, depending on environmental conditions. The integrated water tank holds up to 1.76 gallons of water and lasts for up to 4 hours on maximum speed with just one fill. Additional features include an oscillating fan head, anticorrosive all-metal construction and high-efficiency fan motor.
