The RheoFan provides localized air extraction making a “dynamic” enclosure. The RheoFan maintains slight negative pressure inside the isolator for improved containment. It provides a cross-draft effect for better visibility and lower dust concentration in the enclosure. It also provides inerting capabilities with an inert gas sweep.


The RheoFan has several benefits when implemented in the manufacturing process:

  • Small Footprint
  • GMP Fan Unit
  • Options for Hazardous Areas
  • Control Options


The RheoFan has several control options:

  • Manual (Pneumatic)
  • Manual (Electric)
  • Automatic (Pressure/Environment Setpoints)
