The Evair Dehumidifier RQ Series by DriSteem is a line of refrigerant-based dehumidifiers that deliver dependable humidity control while supporting the transition to lower global warming potential (GWP) refrigerants. The series includes six models with moisture removal capacities ranging from 4 to 31 lb/hr (100-730 pints/day), all of which use R-454B refrigerant.

The dehumidifiers can be used in healthcare facilities, museums, archives, educational institutions, office buildings, and other environments where excess moisture can negatively impact people, equipment, or building performance.
