The stand-alone AD-IS format places the Bendix Air Brake Dryer in a combined air-treatment and pressure-protection role. A 1/2-14 NPT supply port handles incoming compressor air before the unit routes treated air toward protected delivery circuits. The Bendix K049086 opens its auxiliary and secondary outlets at 112 psi, and the safety valve is set for 153 psi. Those pressure points establish how this version manages protected delivery, while the stand-alone layout distinguishes it from integrated dryer arrangements elsewhere in the Bendix range.
