DBP Series Desiccant Regenerative Blower Purge Dryers

The Sullair desiccant regenerative dryer family is ideal for outdoor piping and operations that require an extremely low dew point to -40°F (-40°C) (-4°F [-20°C] or -100°F [-73°F] optional). By combining the proven benefits of desiccant drying with the most advanced designs, Sullair offers a reliable system to clean and compressed air for the most critical applications.

Desiccant dryers adsorb moisture from the compressed air as the air passes through the desiccant. DBP Series dryers regenerate the desiccant using a blower to pass ambient air through a low watt density heater (heated air can absorb more moisture). The dual tower design allows for continuous adsorption of moisture by alternating the adsorbing and regenerating towers.

Models vary by region. Please contact your Sullair sales representative for more details.
