BioPak 240R Revolution (closed circuit SCBA)

The Biomarine BioPak 240 Revolution (closed circuit SCBA) is the most highly advanced, easiest to use 4-hour rebreather ever offered. With 6 liters of tidal volume, it delivers the lowest resistance breathing of any rebreather available. The BioPak 240 Revolution (closed circuit SCBA)cuts return to service time by 50%.

A revolutionary, solid CO2 scrubber designeliminates the need to measure and refill CO2 absorbent as well as potential for refilling errors.

A quick-change cooling system lets you change out the canister’s coolant while unit is being worn without breaking into the breathing loop or removing the external housing. Designed for safety, developed for reliability, this revolutionary self-contained breathing apparatus (SCBA) will out-perform any other unit on the market.
