PURPOSE: To realize an blast quantity control method which can feed a specific blast quantity even when a filter member provided to a blower is blinded. CONSTITUTION: This is an air blast quantity control method of a blower 3 composed by providing a means to detect the blast quantity or the blast pressure, and an inverter 18 to the power source circuit 17 of a driving motor 16, and the inverter 18 is controlled depending on the detecting signal of the means to detect the blast quantity or the blast pressure, so as to control the rotating frequency of the driving motor 16 to make the blast quantity to a preset specific blast quantity, and at the same time, the control scope of the inverter 18 is set beforehand, and when the inverter 18 reaches to the upper limit of the control scope, a warning is output. |
