Respirator upgrade protects workers exposed at altitudes up to 10,000 ft.

April 8, 2014

3M has announced the launch of its Adflo Turbo Assembly with High-Altitude Upgrade, a powered air-purifying respirator (PAPR) system that provides continuous filtered air to welders working at altitudes of up to 10,000 ft.

The system is designed to compensate for air-density changes that occur with an increase in elevation. It also comes standard with a lithium-ion battery to reduce overall respiratory system weight by about 20 percent.
