Specifications shown below are at an air temperature of 75° F (24° C) and a supply air pressure of 125psi (8.6
bar). These specifications are intended to be a baseline to result in the production of 95% pure nitrogen. The
output flow of nitrogen has been pre-set to 3.2 scfm (5.1 Nm³/hr) per membrane. Changes to air temperature,
supply air pressure or supply air flow will change the result of nitrogen purity.
