Rebreather Series

What is CCR scrubber breakthrough? Learn how absorbent exhaustion, channeling and bypass can reduce CO₂ removal, why active Sofnolime alone does not guarantee scrubber performance, and why gas flow matters.

How long does a CCR scrubber last? This article explains what really determines CCR scrubber duration, including scrubber design, absorbent, temperature, workload, storage, monitoring systems and manufacturer operating limits.

How does a rebreather scrubber work? This article explains how Sofnolime removes CO₂ from the breathing loop, why the scrubber produces heat, how the active reaction zone moves through the absorbent, and what ultimately leads to scrubber breakthrough.

How does a closed-circuit rebreather actually work? This guide explains the core principles of CCR diving, including the breathing loop, oxygen control, CO₂ removal, and what makes a rebreather fundamentally different from open-circuit scuba.
