ABSTRACT:
A modular respirator system has interchangeable facial lenses and body seals such as a full facepiece seal or a hood. A method of conversion from a full facepiece respirator to a hood respirator, or vice versa, is also disclosed. In one embodiment, lens conversion is accomplished without changing the type of body seal. In another embodiment, a breathable gas delivery conduit is connected to the facial lens and interchanged between the body seals together with the facial lens.
