Powered respiratory protection optrel swiss air

The swiss air is a fan-assisted respiratory protection system of protection class TH3/TM3. A ventilated half mask completely covers mouth and nose and is supplied with purified air by a miniaturised blower worn on the back. The resulting positive pressure supports breathing and removes the tiring breathing resistance of conventional masks.

The black textile half mask (“loose fit”) is foldable, ultra-light and freely adjustable with its head strap, so no fit test is required. It also suits wearers with a beard and gives TH3 protection with up to 99.8% pure air. As an option, the white silicone half mask (“tight fit”, sizes S, M, L) with a viewing window is available; with a regular fit test, a clean-shaven face and full ventilation mode it reaches TM3 protection with up to 99.95% pure air.

The filter system is chosen to match the environment: the TH3P particle filter (included) removes fine dust, smoke, vapours and viruses, as generated in welding, grinding or cutting. Available separately are the ABE1P and A2P combination filters against gases and vapours, the Mountain Breeze odour filter and the pre-filter. The optional control panel shows filter and battery status, adjusts the air flow steplessly and compensates for altitude and temperature; without it the system can be connected to the optrel app by Bluetooth.

The swiss air can be worn independently of other protective equipment and combined with a helmet or face shield of your choice. Typical applications are welding technology and the metal industry, construction and demolition, painting and coating, woodworking, chemicals and pharmaceuticals, laboratories, waste management and mining. It must not be used where there is an immediate danger to life or health (IDLH) or in atmospheres with less than 17% oxygen.
