Operating principles
The air inhaled through the inhalation valve in the connecting piece is fed into the mask
and flows in the inner side of the visor thus preventing misting. The air enters the inner
mask through the check valves and after use by operator, is exhaled through two exhalation
valves. The operation of a positive pressure respiratory protection device connected to the
masks, for the models that contain the letters SP/A, is made possible by the exhalation valve
equipped with positive pressure spring. Thanks to the above valve, the air pressure inside
the mask is always above the surrounding air pressure, thus allowing a very high safety level.
