The Liberator series offers liquid oxygen reservoirs for home use in two different sizes. The larger 45-litre reservoir is for long-term use, while the smaller 20-litre reservoir is easy to bring along, for example, when travelling. The advantage of the Liberator reservoirs is that they have two filling ports, one for side fill (SF) and one for top fill (TF). Side fill makes filling a portable liquid oxygen device less strenuous. The reservoir also has a fixed flow regulator, which allows continuous-flow oxygen delivery.
