To provide a blower device capable of supplying a proper amount of combustion air even in a case where an air temperature varies.SOLUTION: A blower device 5 that supplies combustion air to a boiler device 1 that can set a plurality of combustion states, comprises: a blower 20; an air temperature sensor 24 that detects a temperature of combustion air; a calculation unit 112 that calculates corrected rotation speed information Aa of the blower 20 by the following equation (1), based on the temperature detected by the air temperature sensor 24; a temperature correction coefficient setting unit 113 that sets a temperature correction coefficient α of the following equation (1) within the range of 0.5<α<1; and a blower control unit 110 that controls the blower based on the corrected rotation speed information Aa calculated by the calculation unit 112. Aa=A0×(Ta/T0)α ...
