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.
