Abstract: An air compressor includes a motor, a compression mechanism configured to be driven by the motor to generate compressed air, a tank configured to store the compressed air, a controller configured to control driving of the motor, an air extraction port configured to extract compressed air from the tank, and an extraction pressure sensor configured to measure an extraction pressure that is a pressure of compressed air extracted from the air extraction port. The controller is configured to control the driving of the motor by referring to the extraction pressure.
