Abstract
A safety helmet fan system includes a fan housing carrying a fan and configured to be mounted on an exterior of a safety helmet shell above a brim of the safety helmet shell, and an elongate cooling air duct connected to the fan housing to direct cooling air flow from the fan housing around the brim and into an interior of the safety helmet shell. The duct can have a flexible construction that allows the duct to be selectively reshaped to accommodate different safety helmet brim configurations. The duct can have a releasable connector configured to releasably connect the duct to a brim of a safety helmet shell.
