HELICOPTER PILOT & AIRCREW SUPPLEMENTARY OXYGEN SYSTEM (HPASOS)

The HPASOS system is a pneumatically powered pulsed oxygen delivery system, designed specifically to protect the pilots and aircrew of unpressurized rotary wing aircraft from the effects of hypoxia when flying at altitudes over 8,000ft.

The Oronasal Mask Assembly has been designed in conjunction with the POD Unit, again as a key component of the HPASOS system. 

KEY FEATURES

• Includes communications.
• Easy to connect to the user helmet.
• Easy to tighten onto face - one-handed operation.
