Water jeopardizes everything you want your compressed air system to do. It ruins product and fouls processes. Removing it is vital in order to protect both your equipment and your operations.

Sullair Refrigerated Air Dryers reliably remove harmful moisture and contaminants from compressed air, helping protect your compressed air system, machinery and downstream tools.

  • Engineered to save
  • Consistent, reliable dew point performance


20 – 30,000 cfm
.57– 849.5 m³/min
  • Stainless steel heat exchangers for consistent dew point and corrosion resistance
  • 3-in-1 heat exchangers with internal separator and evaporator provide simplified maintenance and parts and reduce size
  • Advanced digital scroll compressors for the highest performance with reduced power and energy consumption (200 scfm and above)
  • Zero air loss drains to remove condensate from the system without losing compressed air
  • Environmentally friendly R-134a and R-404a refrigerants standard
  • High heat transfer and large flow areas ensuring low pressure drop
