Methods, systems, and apparatus for setting a rotational speed of a rotor of a compressed-gas dryer system, without communication from an associated compressor (e.g., without knowing compressor speed or load). Such communication is not always practical or possible (e.g., in the case where a dryer may be provided by a different manufacturer as compared to the compressor). In such a case, the speed or load at which the dryer should run can be determined by making an FAD calculation, so as to determine the volumetric flow rate through the inlet into the drying zone of the dryer. This measurement can be made at the inlet (a venturi or other nozzle), or elsewhere in the system (e.g., other inlets or outlets). Determination of flowrate of compressed-gas to be dried can be done independent of any communication with the compressor. This can be done by measuring inlet temperature, pressure, and pressure drop.
