ductcommercialgalvanised steel

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 Application 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.
