Vacuum regeneration forms the logical further development from blower regeneration. The material difference arises from the fact that the required quantity of regeneration air is no longer provided by means of a pressurising blower but by using a suction pump. In order to satisfy the demand for higher reliability at constant compressed air and dewpoint quality, while avoiding the waste of compressed air as purge air, the new dryer standard for externally vacuum regenerated adsorption dryers was created.
