The Baby Booster is intended for the traveling rebreather diver and allows both oxygen and diluent tanks to be filled when compressed air is the only source of power available. It will fill rebreather size dive tanks to 200 bar (3000 psi) when the supply tanks are as low as 34 bar (500 psi). With a weight of only 3.2 kg (7 pounds) it is light enough to be conveniently transported by air.
