Abstract
A respirator kit which includes a contoured plenum; a breathing mask or hood; an air supplying device, such as a powered air purifying respirator or self contained breathing apparatus; and an air hose. The contoured plenum has a low-profile and can be fluidly connected between the respirator mask and hose, and replaces the conventional air hose connection traditionally associated with powered air devices. The plenum is contoured to follow the profile of the mask, reducing the profile of the airway into the mask. The plenum includes a connector by which the plenum can be attached to the inlet of the mask, and can also include a demand valve.
