- Innovative mixed flow impeller with high performance blade geometry.
- Heavy duty galvanised steel construction.
- Can be retrofited 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.
Construction Mixed-Flow impellers are made from high performance injection moulded composite plastic material. Casing made from heavy duty galvanised steel.
Motors
Type - can be supplied with standard direct-drive TEFC/TEAO motors. Electricity supply - single or three-phase to suit a wide range of voltages and frequencies.
Testing Air flow tests based on ISO5801: 2007 Noise tests based on ISO13347: Part 3, 2004
Wiring Diagram See pages N-8, diagrams ER1, 2, 3, 4, 5 for external rotor motors and N-6/7, diagrams DD1, 2, 3, 7, 9 for standard direct-drive TEFC/TEAO motors.

The duct mounted fans shall be of the Vortair® Mixed-Flow Series as designed and manufactured by Elta Pty. Ltd. and be of the model numbers shown on the schedule/drawings.
They shall include a heavy duty galvanised steel circular fan casing.
Impellers shall be made from high performance injection moulded composite plastic material and driven by external rotor or standard direct-drive TEFC/TEAO motors as nominated.
All performance data shall be for a complete assembled unit based on ISO5801: 2007 for air flow and ISO13347: Part 3, 2004 for noise.

* Fan with direct-drive motor - DD
** Fan with external rotor motor - ER
# Weight and volume for fan with direct-drive motor only except where there is only external rotor motors 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.
