Wind: "220V AC Cooling Fan" wind is the wind and sent per minute, or the intake air volume [unit M3 / min (ft3 / min), the number of cubic meters per minute (cfm)]. (CFM or CMM)
Pressure: pressure "220V AC Cooling Fan" fan pressure is needed to overcome the resistance produced by blowing air, into the static and dynamic pressure. Static pressure refers to the direction of air flow parallel to the measured pressure, dynamic pressure is converted into kinetic energy of the gas flow pressure required for the process [Unit: mm / H2O (inch / H2O), the number of water column pressure mm (inches)].
