Balanced Temperatures and Greater Comfort
Warm air naturally rises, creating temperature differences between the ceiling and floor. PureAir directs air downward to mix these layers, helping maintain more consistent temperatures throughout the occupied space.

Built-In PHI-Cell® Air Purification
PureAir integrates RGF’s PHI-Cell® technology into the fan assembly, combining continuous air circulation with air purification. The system helps reduce airborne viruses, bacteria, mold, and odors while enhancing destratification performance.

Lower HVAC Energy Use
By reducing ceiling-to-floor temperature differences, PureAir helps HVAC systems maintain comfortable conditions more efficiently. Destratification can reduce HVAC energy use by 20–35%, supporting energy efficiency and decarbonization initiatives.

Flexible Models and Installation
PureAir offers standard and short nozzle configurations to accommodate ceiling height. Models are available in off-white or black, with 120VAC and 277VAC options.

  • Temperature balance: Reduces ceiling-to-floor temperature differences for more consistent comfort.
  • Energy savings: Destratification can reduce HVAC energy use by 20–35%.
  • Integrated air purification: RGF’s PHI-Cell® technology helps reduce airborne viruses, bacteria, mold, and odors.
  • Continuous air mixing: Helps reduce hot, cold, and stagnant air zones.
  • Directed airflow: A multi-vane stator increases air throw to support effective destratification.
  • Flexible installation: Ceiling-hung design without major HVAC equipment or ductwork changes.
  • Configuration options: Standard and short nozzles, two PHI-Cell® sizes, and off-white or black finishes.
  • Durable construction: Flame-resistant ABS housing, stainless steel hardware, and a thermally protected motor.
  • Low-maintenance motor: Sealed bearings require no lubrication.

PureAir is designed for open-ceiling and high-bay spaces where temperature stratification, uneven comfort, and indoor air quality are concerns. Potential applications include:

  • Warehouses and distribution centers
  • Manufacturing and assembly facilities
  • Retail stores and showrooms
  • Gymnasiums and indoor recreation facilities
  • Workshops and service facilities
  • Commercial spaces with exposed ceilings
  • School and university common areas
  • Large gathering and multipurpose spaces
