Aerox Portable Emergency Oxygen System, 4 Cubic Feet, Single User with Mask

This is the lifesaver that every pilot should have in his or her flight bag. This system gives you enough minutes of oxygen for a single person to safely return to breathable altitudes (time varies with system choice). If the worst occurs and your primary oxygen system fails in-flight, fly easy knowing your backup system is in place.

Features:

• To activate simply pull mask or ring away from tank and oxygen flow is immediate
• Unit's small size fits almost anywhere
• Replaces more costly and dangerous O2 generators
• Refills with ease and very little cost
