Claim:
1. A regenerative air dryer system comprising: a plurality of air dryer modules, each air dryer module having a modular valve cartridge including an orifice opening, wherein different air dryer modules of the plurality of air dryer modules have modular valve cartridges with differently sized orifice openings so as to have air flow rates different from other air dryer modules of the plurality of air dryer modules; and a controller configured to sequence operation of which air dryer modules of the plurality of air dryer modules are operating in an air drying mode to modify an air flow rate of the regenerative air dryer system, where the air flow rate of the regenerative air dryer system is a combined air flow rate of air dryer modules of the plurality of air dryer modules operating the air drying mode.
