Emerson MK6 Rebreather
Menu Semiclosed Rebreathers

Recently I received some nice pictures of the Emerson MK6 Semi closed rebreather. This very early design from the 70's is little known in Europe but was used for many years in de US army. The Emerson rebreather was also called "the Green Death". De rebreather is a constant flow mixed gas SCR. It uses a constant mass regulator  and a needle valve to set the flow. The manual says it is rated for 180 ft (55 mtr) with a premix of 32 % of oxygen resulting in a pO2 of 2,08 bar! The MK 6 was later to be replaced b the MK15.

I want to thank all persons who sent the above pictures to make this publication possible!
A special thank you for Stefan Besier and Steam Machines Inc. !!
