It consists of a drier provided with a filter regeneration timer and a 4-way protection valve incorporating a pressure reducer.
The purpose of the drier is to purify and dry compressed air by adjusting system pressure to its rated value.
The 4-way protection valve distributes air con the various circuits ensuring their operating pressure even in the event of
breakdowns.
This component is used in all systems and is rated at 10.5 + 0.2 bars; for mobile bowl CM vehicle setting is 12.5 + 0.2 bars.
The APU contains two sensors connected to the MUX system for axle pressure display on the Cluster.
