G1 Facepiece

The facepiece provides breathable air from the regulator past an inhalation valve to the inside of the
lens (to minimize lens fogging) and then through the check valves into the nosecup. Exhaled air is
directed out of the exhalation valve by the nosecup directly to ambient air. The face seal provides a
snug, comfortable fit, and tight seal. The facepiece is available in 3 sizes (small, medium, large) and
the nosecup is available in 3 sizes (small, medium, large).
The facepiece is equipped with a mechanical speech diaphragm that enhances speech communica-
tion. The HUD is provided inside the facepiece through light pipes from the regulator.
When in safe atmospheres with no regulator attached, ambient air can be inhaled directly through an
opening to facilitate breathing and speaking with minimal resistance.

Facepiece Versions

The facepiece is available with different head harnesses; fabric (both SpeeD-ON
rubber (5-point).
