ABSTRACT:
A powered respirator helmet comprises a shell, having a passage, between a filter medium, and a fan, mounted in the front peaked part of the helmet shell. An air intake permits air to be drawn by the fan through the filter medium, through the passage and to be exhausted by the fan into the space between a wearer's face and a visor. The helmet is more compact, lighter and less expensive to service than existing respirator helmets, while providing more effective respiratory protection.
