Fan Features

  • Designed for stable, efficient and quiet operation over a wide range of duties.
  • The combination of scientifically designed aerofoil or flat laminar blades with highly desirable non-overloading power characteristics.
  • Components liberally sized to ensure long trouble free life.
  • Universal housing – fan outlet can be oriented in any standard direction. The direction of rotation can also be changed by reversing the housing and substituting an impeller of opposite handing.
  • The combination of scientifically designed aerofoil or flat laminar blades with highly desirable non-overloading power characteristics.
  • Designed for stable, efficient and quiet operation over a wide range of duties.
  • Models J, K, and L Series – Backward inclined laminar impeller blades.
