Claim: The ornamental design for an inlet port adaptor on a full-face respirator lens, as shown and described.
Description: FIG. 1 is a perspective view of a inlet port adaptor on a full-face respirator lens, showing the new design.

FIG. 2 is a front elevational view thereof.

FIG. 3 is a rear elevational view thereof.

FIG. 4 is a right-side elevational view thereof. The left-side elevational view is a mirror image of the right-side elevational view.

FIG. 5 is a bottom plan view thereof; and,

FIG. 6 is a top plan view thereof.

The broken lines form no part of the claimed design other than to illustrate the orientation of the inlet port adaptor on a full-face respirator lens. The shading provided in the drawings is furnished merely to indicate contour; it is not indicative of any particular texture.
