Abstract
An air circulation system is provided that is fittable to a protective helmet. The system includes an external manifold, a removable intake duct, and a removable exhaust duct. The manifold is mountable to an external surface of a protective shell of a helmet and defines an exhaust passage external of the shell having at least one orifice communicable with an interior crown region of the shell and an intake passage communicable with a bottom region of the shell near a wearer's mouth and nose. The removable intake duct is connected to a remote positive pressure source at one end and connected to the external intake passage on the other end. The removable exhaust duct is connected to a remote source of negative pressure at one end and connected to the external exhaust passage of the external manifold on the other end. Fresh air can be circulated to the bottom region by the positive pressure source and exhaust air can be forcefully removed from the crown region by the negative pressure source to provide a complementary air circulation system for the wearer of the helmet.
