Van Air skid mounted compressed air dryer packages provide a complete air drying system in a portable package. Both deliquescent air dryers and regenerative air dryers are available in complete skid mounted compressed air dryer systems which include the compressed air dryer, aftercooler and required filters.

Single tower compressed air dryers are very simple beasts which use an absorbent desiccant. Water vapor is removed from the air as it flows through the absorbent desiccant.
