CO₂ + H₂O → H₂CO₃① CO₂ dissolves in the pellet's surface water film

H₂CO₃ + 2NaOH → Na₂CO₃ + 2H₂O + heat② fast neutralisation by NaOH (catalyst)

Na₂CO₃ + Ca(OH)₂ → CaCO₃ + 2NaOH③ slow step: lime locks CO₂ as chalk, regenerating NaOH

Horizontal axial flow: exhaled gas, with the O₂ and diluent the ADV adds in the exhale lung, enters the black end (diver's left) and runs the bed to the white end and the inhale lung (right). Manual (2.2 kg, 1.6 L/min CO₂, 40 L/min): 135 min at 6 m and 75 min at 40 m in 4 °C water, 60 min at 100 m in 14 °C.
