4 different flow rates of membrane dryers with dew point -13°F (-25?) or less: 1.41 SCFM (40L/min ANR), 3.53 SCFM (100L/min ANR), 10.59 SCFM (300L/min ANR), 17.66 SCFM (500L/min ANR). This hollow fiber film type air drier does not require electric power. Simply connect the piping like a filter, then the Fiber Dry will perform better than a freeze-drier to provide dried air.
