Air supply attachment for a helmet

The present invention relates to a personal respiratory protection device, in particular, such a device comprising a respirator body having a periphery, a filter media, forming at least part of the respirator body, and a gasket, the gasket being located at the periphery and extending along at least a portion of its length.

Personal respiratory protection device

A respirator has a shell that defines a breathable air zone for a user wearing the respirator. An air flow control system for the respirator has an air delivery conduit within the shell of the respirator, a valve member moveable relative to the air delivery conduit and within the shell to vary the amount of air flow through the air delivery conduit, and a valve actuator outside of the shell of the respirator. The valve actuator is manipulatable by a user of the respirator while wearing the respirator to control movement of the valve member.

Respirator flow control apparatus and method

A respirator system is disclosed that includes a foldable head cover assembly including a face seal portion. The respirator assembly further includes a visor assembly attached to the head cover assembly and a head suspension system removably attached to the visor assembly. The visor assembly and the head cover assembly on one hand, and the suspension system on the other, are separable and foldable to enable storing and/or shipping the same separately. A head suspension system is also disclosed.

Respirator system including removable head suspension

A powered air purifying respirator (PAPR) for delivering a forced flow of filtered air to a wearer is disclosed. The PAPR comprises a turbo unit with turbo unit components including a fan, an electric motor, and an electronic control unit having a wireless electronic control transceiver, the fan being driven by the electric motor under the control of the electronic control unit and the electronic control unit being configured to send and receive information via the electronic control transceiver; a turbo unit power source that provides power to the turbo unit components; a turbo remote control unit having a wireless turbo remote control transceiver; at least one turbo status indicator unit, adapted to indicate a current operating status of the turbo unit and/or turbo unit components, having a wireless turbo status transceiver; wherein at least one of the turbo remote control unit and turbo status indicator unit is remote from the turbo unit, and wherein at least two of the electronic control transceiver, the turbo remote control transceiver and the turbo status transceiver are in wireless communication with each other.

Powered air-purifying respirator

A respirator assembly has a shell that defines a breathable air space for a user wearing the respirator assembly. The respirator assembly has an air delivery conduit within the shell for providing air to the breathable air space. The air delivery conduit has an air outlet that is either adjustable in configuration or has a vane associated therewith that is adjustable in position so that the direction of the air exiting the air outlet is controllable between first and second air flow directions. The user is able to control the direction of air exiting the air outlet while the respirator assembly is worn by the user.
