Abstract: A low oxygen air supply system includes first and second low oxygen air supply units, a fan to supply the first target space with outdoor air, at least one oxygen sensor to detect oxygen concentration in the first target space, and a control unit to control behavior of the first low oxygen air supply unit, the second low oxygen air supply unit, and the fan. Each of the first low oxygen air supply unit and the second low oxygen air supply unit generates a low oxygen air lower in oxygen concentration than air and supply a first target space with the low oxygen air thus generated.
