Liquid Air Breathing Technology

Our Mission

Provide information to demonstrate the advantages of using cryogenic air for respiratory protection. Current and historic technology uses compressed air which has evolved to very high, hence hazardous levels (5000 psi).
Cryogenic Air offers: Higher density at low pressure, typically < 75 psi, therefore lighter weight storage vessels.

NASA Technology may Breathe Life, Safety into Mines

Rebecca Regan, John F. Kennedy Space Center

A technology used by NASA to protect crews working around hazardous gases soon could be called on for a number of life-saving applications as well as the agency’s new human spaceflight endeavors.

The Cryogenic Refuge Alternative Supply System (CryoRASS) and a smaller liquid air-filled backpack under development in Kennedy Space Center’s Biomedical Lab have the potential to store more than twice the amount of breathable air than traditional compressed gas systems.
