The powered respirator is used for dust and particles removal only, not for gases or vapors
and is used to reduce or remove resistance to inhalation during respiration by producing a
constant airflow. The unit is designed with manufacturer’s minimum design flow rate 170 litres
per minute (the flow rate at which the equipment still will fulfill the requirements of the class in
EN12941:1998 + A1:2003 + A2:2008). The actual working time will be about 8 hours.
