Claims (1)

[Scope of utility model registration request] an air compression device; a drain device that removes drain of compressed air discharged from the air compression device; and a drying device that uses a renewable desiccant to remove moisture from the compressed air supplied from the drain device through a check valve;
an air storage tank that stores dry compressed air from the drying device; a drain valve that is provided on the air compressor side of the drain device and connects the inside of the drain device to the outside air in response to an external command; and a drain device side of the drying device. a regeneration valve that connects the desiccant drain device side to the outside air in response to an external command; and when the pressure in the air storage tank reaches an upper limit value, a command is given to the drain valve and the regeneration valve to reduce the pressure to the lower limit value. In a compressed air pressure source device equipped with a governor device that cancels a command when a command is reached, commands from the governor device to a drain valve and a regeneration valve are performed by supplying compressed air, and the operation of the drain valve is faster than the operation of the regeneration valve. Compressed air pressure source device made to be carried out first.
