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.

A fluid flow component has a fluid connection. The fluid connection has part circular end portions and extending side portions connecting the part circular end portions. A seal groove is formed in the fluid connection. The seal groove has inwardly extending components at an outer end to capture an o-ring within the seal groove. A circular o-ring has a circular cross-section received within the seal groove.

An environmental control system includes an air conditioning subsystem; a mix manifold downstream of the air conditioning subsystem and upstream of an environment to be conditioned; and a contaminant removal subsystem downstream of the environment to be conditioned. The contaminant removal subsystem includes a first gas-liquid contactor-separator. The first gas-liquid contactor-separator includes a first packed, stationary bed that provides a heat/mass transfer surface for contact between a contaminated air from the environment and a liquid absorbent.
