Wind means "Inflatable Air Blower" discharge of air per minute or included total volume, if calculated according to cubic feet, the air volume units that CFM; if you press m to count, that is CMM. Air volume units "Inflatable Air Blower" is often used CFM (approximately 0.028 m3 / min). Air flow is a measure of the most important indicators of the cooling capacity of the cooling fan. Obviously, the larger the amount of wind "Inflatable Air Blower" its cooling capacity is also higher. This is because the air in the heat capacity ratio is certain, larger air volume, which is more air per unit of time can take more heat. Of course, the same air volume flow of the cooling effect of the wind the way.
