High autonomy self-rescuer mask - EBA 6.5

EBA 6.5 self-contained self-rescuer with high autonomy

The EBA 6.5 is a highly reliable self-contained self-rescuer breathing apparatus tested in life-threatening situations throughout the world. It supplies over 90 minutes of oxygen during a typical mine escape — up to 8 hours of oxygen at rest — a performance that exceeds all MSHA and NIOSH standards. 

Oxygen from the breathing bag is inhaled through the inhalation tube and the mouthpiece. Breathed air is exhaled through the mouthpiece into the CO2 scrubber.Oxygen delivery ranges from 1.5 l/min constant flow up to 100 l/min demand flow.

The oxygen content indicated on the SCSR gauge is always visible for inspection through the clear, tamper-proof sealed case.

• Hight autonomy: over 90 minutes oxygen in demand mode; up to eight hours in conservation mode.
• Quick to don: can be put on and be fully operational in 15 seconds or less.
• Easy to operate: turning on the valve activates the system; turning it off allows oxygen conservation.
• Lightweight: donned weight 8.0 lbs (4.17 kg). With composite cylinder only 7.0 lbs (3.17 kg).
