Abstract: A modular, multi-crew life support system and a method of assembling the system involve a fan to draw in ambient air. The system includes one or more assemblies that produce conditioned air from the ambient air, and a housing to support an oxygen source. The system also includes a port configured as an inlet from the oxygen source to augment the conditioned air, and a duct to disperse a result of augmenting the conditioned air as output air to support two or more occupants of an enclosure.
