Abstract
A personal protection system is mountable to a user for distributing air to the user includes a shell providing structure. A fan module is supported by the shell for generating a flow of air. Cushioning is provided between the fan module and the shell to reduce vibrations and noise. The fan module includes a fan with blades having an airfoil shape for added noise reduction. An air flow channel is in fluid communication with the fan module for routing the flow of air. A pair of nozzle tips are in fluid communication with the air flow channel and are rotatably adjustable to allow directional adjustment of the flow of air toward a neck of the user. The personal protection system also includes a face shield with multiple removable layers which are sterilized as a unit using gamma radiation.
