Originally designed to meet the requirements of Special Operations Forces, the O2PAK is a non-explosive oxygen source. It requires zero maintenance, no refilling, and no power source or battery. It is small enough to fit in a military pack and is able to operate in any environment from high altitude to desert heat. The O2PAK is the oxygen solution for use immediately following an injury no matter how hostile a situation is. It will be the oxygen source until the a safe setting can be reach or an EVAC is obtainable.
