Abstract: A respirator system includes a respirator with an air filter, a flow generator with a sensorless DC motor, a mask, a processor, a sensor, an electric power source, and a wireless transceiver. The respirator filters air, increase the pressure of the air, delivers the air to the mask at a pressure above ambient, gathers data with the sensor about operation of the respirator, and transmits the data. An intermediate electronic device is separate and remote from the respirator, and is configured to receive the transmitted data process the data, and re-transmit the data. A computer receives the data, processes the data and generates at least one report regarding the respirator or a user of the respirator.

Abstract: The present invention relates to improvements to powered air purifying respirators (PAPR). PAPR are known generally for use in polluted environments. A typical PAPR comprises a powered impellor arranged to draw air from the atmosphere, a filter element and a mask to provide the filtered and pressurized air to the user. Embodiments of the present invention place a generator unit, comprising a filter and impellor for pressurizing the air, behind the head of the user, and include components for improving delivery of the air to the user and improving its quality.

Abstract: A filter assembly for a breathing apparatus, such as a powered air purifying respirator. The filter assembly includes a frame for receiving and retaining a filter element, a cover connected to the frame and dimensioned to cover the aperture, a filter element, and an indicator for indicating when the filter element is retained in the filter frame and the cover is arranged across the aperture. A powered breathing apparatus including the filter assembly is also disclosed.

Abstract: A breathing apparatus including a face mask adapted to substantially cover a face of a user and a neck component attached to the face mask and surrounding the user's neck. The face mask has a peripheral region which forms a pneumatic seal against the face and an air inlet arranged proximal to the peripheral region. The neck component houses a flow generator configured to receive unfiltered air from outside of the breathing apparatus, filter the unfiltered air, and convey the filtered air to the face mask through the air inlet.
