CUD Series In-line Fan    
|
  |
- The Vortair® Series of In-Line Fans is designed for a wide range of duct mounted applications.
- Their innovative high performance mixed flow impeller produces powerful airflows without generating high noise levels.
- They feature a heavy-duty galvanised steel circular fan casing that can be retrofitted into axial fan installations that may require greater static pressure.
- They are available in various speed options and 6 case sizes with diameters ranging from 400 to 710mm (250 to 450mm impeller diameters).
|
Typical Applications
|
- Commercial and industrial supply or exhaust air applications such as shopping centres, office buildings, exhibition centres, hotels, health centres, schools and universities.
|
 Features
|
- Innovative mixed flow impeller with high performance blade geometry.
- Heavy duty galvanised steel construction.
- Can be retrofitted into standard 400 to 710mm axial fan installations.
- Large choice of speeds available.
- Can be mounted in any position.
- A range of matched ancillaries is also available.
|

Note
- Performance curves shown are based on nominal speeds.
- As motor speeds may vary from one manufacturer to another, and from one motor type to another, it is possible actual fan speeds may differ and, therefore, the performance of the fan.
- For Direct-Drive performance refer to Fans by Fantech Selection Program.
