Abstract
A mister for use with fans having blades protected by a guard wherein the mister is mounted on the guard and through a plurality of water atomizing nozzles projects a mist into the fan airflow to produce a cooling effect by the evaporation of the moist air. The mister may be used with original equipment fans, or may be retrofitted to existing guarded fans and economically produces a distribution of water particles within the airflow.
