Xu, air flow volume is not based on voltage or current, but on
cross-section, blade pitch and design, and rotational speed.
Most all fans have a label indicating the manufacturer and model number;
it's usually best to contact them for a full data sheet. Usually the sheet
will include plots of air volume vs. back pressure, which is important to
know when cooling an external anode tube.
