Description

2 Description
The face blank is made of a special soft rubber compound and assures a snug, comfortable fit and a
tight seal. The face blank is also available in yellow silicone. Some versions of the mask are also available in small size.
The inhalation air flows from the connector of the mask past the inhalation valve to the inside of the
lens [thus keeping the lens largely fog-free] and then through the check valves into the nose cup.
The exhalation air passes through the exhalation valve directly to the ambient air.
