Twin Tower Heatless Desiccant Dryers

The CompAir AX-Series uses twin desiccant towers and strategically positioned valves to dry compressed air.

The compressed air is thoroughly dried as it passes through the on-line desiccant-filled tower. While this tower adsorbs moisture, the off-line tower is purged and readied for the next cycle, ensuring a continuous supply of dry air.
