ANCILLARY EQUIPMENT Aviator Aviator Touch & Aviator Touch PRO Controller Ref. Aviator Brochure DESCRIPTION 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 retrofited into standard 400 to 710mm axial fan installations. • Choice of external rotor or standard direct-drive TEFC/TEAO motors. • Large choice of speeds available. • Most 3-phase external rotor motors fitted are 2-speed star/delta design. • To improve energy efficiency, motors can be speed-controlled. • 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 direct-driven external rotor or standard direct-drive TEFC/TEAO motors. Electricity supply - single or three-phase to suit a wide range of voltages and frequencies. Bearings - sealed-for-life, ball. External rotor motors are fully speed-controllable using electronic or auto-transformer controllers, however Sinusoidal filters are required when a variable speed drive is used. Standard direct-drive TEFC/TEAO motors can be single or multispeed and can be speed-controlled using a variable speed drive. See pages O-2/3 for details on external rotor motors and pages O-3/4 for details on standard direct-drive TEFC/TEAO motors. Internal Thermal Protection Automatic-reset type is fitted as standard to external rotor motors and is an optional extra on standard frame motors. 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. SUGGESTED SPECIFICATION The duct mounted fans shall be of the Vortair® Mixed-Flow Series as designed and manufactured by Fantech 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.

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.
