The WS-Platypus Mk1 is a O2 CCR with manual O2 addition.
WS in honor to the late Will Smithers who gave us the idea to connect the inhale and exhale lungs directly to the DSV.
The counterlungs are made of Harley Davidson inner tubes and have about 5 liter capacity.The scrubber can hold up to 2,4kg of Sofnoline.
