The Balston Model 75-A20 regenerative PSA desiccant dryer reduces the atmospheric dewpoint of compressed air to -100°F (-73°C) without operator attention, providing reliable ultra-dry air for moisture-sensitive applications.
Designed for industrial and laboratory use, this lightweight and compact dryer supports unattended 24-hour operation while protecting equipment and processes from moisture, condensation, and corrosion.
Installation is simple — attach the inlet (60 psig/4.1 BARG minimum) and outlet air lines, plug the electrical transformer into a wall outlet - no electrician required - and the unit is ready for trouble-free operation. Its design allows it to be easily installed, operated, and maintained by personnel not trained in instrumentation.
Ideal for environments where air comes into contact with moisture-sensitive materials or when outside compressed air lines are subjected to sub-freezing temperatures, the Balston 75-A20 uses pressure swing adsorption technology to continuously remove moisture and requires no desiccant to change, minimizing downtime and maintenance costs.
