This is a generic counterlung designed for rebreather self-builders or as a replacement unit for custom projects. It is manufactured with fully customizable ports – you tell us where you need the connections, what size, and what type of fitting (e.g., for manual addition valves, hoses, sensors, or blanking plugs) .
Made from durable, gas-tight materials suitable for CCR or SCR use. No stock configurations – just a clean, functional lung built to your exact specifications. Ideal for prototype work, one-off builds, or replacing obsolete parts.
