ABSTRACT:
A compact, integral forced-ventilation personal respirator device for the breathing space in a gas mask, protective helmet or hood, or the like, comprises a housing including a connector for air-tight connection of the housing to the breathing space to be protected, an electric blower removably attachable to the housing and comprised of an electric motor stationary relative to the housing in the attached state of the blower and a bladed centrifugal-type rotor fixedly mounted on the output shaft of the motor, a compartment inside the housing for accommodating a filter medium, the compartment facilitating access of the output air from the blower to the filter medium, and egress of the filter air from the medium to a space communicating with the connector of the housing, whereby ambient air is drawn into the housing by the blower and forced thereby via the filter medium into the breathing space to be protected.
