HEED 3 - 3.0 CU. FT. Cylinder SIZE - 175 Series (Helicopter Emergency Egress Device)
The popular HEED 3 is the latest generation of Helicopter Emergency Egress Devices manufactured by Submersible Systems. A compact, lightweight and reliable self contained breathing apparatus, the HEED 3 is designed to increase the survivability of military and commercial personnel in short-term out-of-air emergencies. Model 175-001 is the preferred choice for aircraft use due to its small size and ease of mounting on a flight vest. Holster has straps that easily attach to MOLLE type vests. Holster and Dial Gauge Pressure Indicator included.
