Blower purge regenerative dryer is a regenerative blower, which moves atmospheric air into the circulation heater where it is heated and directed to the left desiccant bed for regeneration. The hot absorbent purge air enters the desiccant bed from the top and flows down heating the desiccant bed and collecting moisture from the desiccant. The now moisture laden purge air exits the system through the purge valve and muffler.
