Technology Details
The Revolutionary Positive-Pressure Protection Concept
The swiss air system completely separates respiratory protection from face and eye protection. At its heart is a ventilated half mask made of flame-retardant material, which is supplied with filtered air. Constant positive pressure is maintained in the breathing zone (nose and mouth), pushing contaminated ambient air away so that you cannot inhale it. This design not only protects but also actively assists breathing, which significantly reduces fatigue during long hours of intensive work. Investing in a positive-pressure system is an investment in all-day comfort and productivity without a feeling of breathlessness.
Certified Class TH3 Respiratory Protection
Dust produced during grinding, cutting or machining is a direct health hazard. The swiss air system provides the highest possible level of protection (class TH3 according to EN 12941), filtering at least 99.8% of harmful solid and liquid particles, including dust, fumes and aerosols. Intelligent electronics integrated into the control panel continuously monitor the airflow and the filter condition, so full protection is maintained throughout the working cycle. This is not just a piece of equipment, it is a fundamental investment in protecting your own health and in being able to work safely for many years.
Full Freedom and Modular Design
The filter and blower unit weighs only 550 grams and is worn on the back in a well-fitting, ergonomic harness, which takes the load off the head and neck. The key advantage of the swiss air system is its versatility: it can be used with the supplied clearmaxx shield, but also under any welding helmet (including other brands), a safety helmet or a face shield. The system does not require time-consuming fit tests, which makes introducing it and using it every day simpler. Choosing swiss air is an investment in a flexible, future-proof solution that adapts to every task in your workshop.
