Optrel’s new Swiss air-powered air-purifying respirator (PAPR) is a comfortable system that welders can use alone or with a helmet or hood. The 1.2-lb., low-profile PAPR is worn as a backpack with ergonomic shoulder harnesses that maximize freedom of movement. Controls and filter and battery indicators are front-mounted for easy visibility and access. The variable airflow is continuously adjustable to personalize fresh air delivery. The high-performance battery provides a full 14-hour workday of power. The system features an internally tested assigned protection factor greater than 1,000.
