Abstract
A control load is reduced in a fan unit capable of controlling air flow volume. The rotation speed of a fan can be changed. An air flow volume detector detects air flow volume of the fan or equivalent air flow volume that is a physical quantity corresponding to the air flow volume of the fan. A unit casing houses, therein, the fan and the air flow volume detector. A fan controller, which is a controller, controls the rotation speed of the fan. The fan controller controls the rotation speed of the fan on the basis of a command value of the air flow volume of the fan given from outside the unit and a detected value of the air flow volume or the equivalent air flow volume detected by the air flow volume detector.
