Claims

[Scope of utility model registration request]

In an air supply device that supplies air requested by multiple users by parallel operation of multiple compressors, there is a program setting means for setting the amount of air required by each user, and the output of these program setting means is controlled for a certain period of time. dead time setting means for supplying the set value to each user's air flow rate controller means with a delay; addition means for calculating the total required air amount by summing up the outputs of the program setting means for each user; and this addition means. An air supply control device comprising operating number control means for determining the number of operating compressors based on the output of the air supply controller.
