PURPOSE: A dehumidifier for an air compressor in an oxygen generator is provide to prevent a dehumidifying agent for separating oxygen and nitrogen in an oxygen generating part from reducing the efficiency of oxygen generation. CONSTITUTION: A dehumidifier for an air compressor includes a cooling cycle part(10), an oxygen generating part(20), and a controlling part(30). The cooling cycle part includes a compressor(11), a condenser(12), an expansion unit(13), and an evaporator(14). The expansion unit expands coolant such that the coolant of the low temperature and high pressure becomes the coolant of the low temperature and low pressure. The evaporator heat exchanges wet air with the coolant of low temperature and low pressure, and the wet air is dehumidified and cooled. The oxygen generating part includes an air compressor(21), a solenoid valve(22), and an absorption column(24). The air compressor compresses dehumidified air to obtain compressed air. The absorption column separates hydrogen from the compressed air and exhausts oxygen. The controlling part controls the cooling cycle part.
