Th Evolution is designed for effective climate control for smaller areas with restricted clearance for the fog. The misting fan is suitable for cooling, humidification and limited dust control applications and provides 250 cfm using 0.12 amps at 230V. The mist fan covers up to 1,000 sq. Ft or 1,000 cu.ft. The cannon design and the internal guide fins produce a strong and focused air stream which projects the fog up to 50ft from the unit making it ideal for low ceiling applications. The Evolution is designed to provide a projection of fog over longer distances with a narrower focus range. The unit can effectively cover an area of 20ft in width and up to 50ft in length. The unit will provide better absorption of the moisture from the system, and a more uninformed distribution of the fog.
