Regenerative air dryers


Aggressive Air Compressor co. is a factory Authorised distributor for Sullivan-Palatek and Great Lakes Air dryers

Dry compressed air keeps lubricants from being washed away from air tools, cylinders, air motors, and valves extending product life and reducing maintenance. It reduces distribution system corrosion that will increase pressure drop and operational costs, generate pipe scale, cause leaks, and require premature replacement. It also reduces product contamination in applications like, mixing, conveying, agitation, cooling, or product blow down.

A regenerative dryer delivers a dew point of approximately −40 °F (−40 °C)

The compressed air enters the dryer where it is passed through one tower of a pressure vessel with two towers. These towers are filled with a desiccant material which attracts the water from the compressed air via adsorbtion. The other tower is, at the same time, being purged of moisture. The dryer is timed to switch towers based on a standard NEMA cycle. The saturated desiccant is dried by one of three methods.

Heatless dryers

A portion of the dried compressed air leaving one tower is bled off and passed through the other tower where it purges the captured moisture from the desiccant and is then vented to atmosphere. This purge air bleed causes a pressure and flow drop of the delivered air of up to 15%.

For low volume usage (5-35cfm) which is ideal for small laboratories or point of use needs we recommend the GMR series dryers from Great lakes Air.

Heated dryers

A portion of the dried compressed air leaving one tower is bled off and heated before passing through the other tower where it purges the captured moisture from the desiccant and is then vented to atmosphere. This requires substantially less purge air than a heatless dryer.


Externally heated blower dryers

The heated purge air is generated by a separate blower thereby eliminating the pressure and flow drop caused by bleed air purging.
