Introduction

Cycle Stage

Air Flow

When the compressor unloads, the purge

valve opens. On the System Saver HP:

Dry air flows from the integrated purge

tank back through the air dryer. Air can

be felt and heard flowing from the purge

valve for an extended period of time.

Dry system air flows back through the

air dryer to regenerate desiccant.
