Technology Details
Positive Pressure in the Breathing Zone
The half mask is an integral part of the swiss air system, which delivers a stream of clean, filtered air to it. This creates constant positive pressure around the nose and mouth, which acts as a barrier to contaminants from the surroundings. This active protection not only prevents you from inhaling harmful dust, fumes and aerosols but also physically assists breathing, reducing breathing effort and fatigue during intensive work. Investing in positive-pressure technology is a direct investment in protecting your lungs and your general condition, and it allows longer and more comfortable work.
Flame-Retardant Material
Safety in a welding environment is an absolute priority. That is why the half mask is made of a specially selected, technically advanced material with flame-retardant properties. It protects the wearer's face from accidental contact with hot welding spatter or sparks, which are an unavoidable part of welding and grinding. The certified material minimises the risk of ignition and burns and forms a key layer of passive protection. It is a fundamental element that gives you peace of mind and lets you focus fully on the precision of your work.
Ergonomic "Tight-Fit" Design in Size L
The "tight-fit" version was developed specifically to give even better contact and sealing around the nose and mouth. Thanks to its flexible construction and precise profiling, the half mask adapts closely to the anatomy of the wearer's face, eliminating leaks and maximising the efficiency of the positive-pressure system. Size L is intended for welders with a larger head circumference or a particular facial build and gives comfort without pressure points. A well-fitting half mask ensures that the respiratory protection system works at its highest certified effectiveness throughout the working day.
