Abstract
A powered air-purifying respirator (PAPR) carriage and assembly includes: a blower assembly configured to draw in and purify ambient air; a power source operably connected to the blower assembly; and a carriage, which is configured to be worn by a user and to receive and carry the blower assembly and the power source. The carriage includes a main body that is configured to be worn on the shoulders of the user and includes a first cavity for receiving the power source and a second cavity for receiving the blower assembly. The first cavity and the second cavity are defined by portions of the main body positioned on opposing anterior and posterior sides of the user when worn. When the PAPR carriage and assembly is in use, the carriage thus causes the weight of the blower assembly and the power source to be distributed across the upper body of the user in a counterbalanced manner.
