The unit supplies an overcapacity of clean and filtered ambient air, which is fed to an air hood or mask. It allows the user to breathe in air without himself having to overcome the resistance of the filter. Considering that an adult person requires some 50 litres of air per minute, the overcapacity ensures an overpressure and thus a high degree of protection.
With a fully charged battery the unit will operate for at least 4 hours using an airhood and 8 hours using a mask. The insert socket from the hose determines the airflow: 280l/min. using a hose with a bayonet connector (air hoods), and 180l/min. using a hose with an EN thread connector. The unit contains a warning facility to warn the user against reduced air supply, due to clogged filter or low battery.
