Technology details
Optimised exhalation valve for maximum tightness
The exhalation valve is a critical component of the swiss air half mask. It is responsible for correct air circulation and for keeping the protected zone intact. Its precise one-way design lets exhaled air, rich in carbon dioxide and moisture, flow freely out of the mask. At the same time the valve membrane closes immediately and hermetically at the end of each breath out, so no contaminated ambient air can flow back in. This keeps a constant, safe positive pressure inside the half mask. The "tight fit" designation refers to the perfect sealing of the valve itself, which is the basis of the whole system's effectiveness. Replacing this part regularly keeps the system working at maximum performance. Investing in this original component is a direct investment in the reliability of your respiratory protection system and in your working comfort.
