An air drying mechanism for a compressed air braking system includes a housing containing desiccant material, and a purge volume which stores air for backflowing through the desiccant to purge the latter of its moisture content. A flow regulating control valve is located between the purge volume and the desiccant to provide a constant flow rate of purge air through the desiccant during purging.
