FlexLine Series – FLD566DD
Performance Curve - FLD566DD
Description
The FlexLine Series of backward-curved centrifugal fans has been developed for ducted applications requiring high pressures.
They are available in various speed options and 8 sizes, extending from 315 to 710mm diameter.
Features Single-width, single-inlet housings.
Robust galvanised steel and aluminium construction.
High efficiency, low noise backward-curved centrifugal impellers.
Large choice of speeds available.
Easy to fit 35mm TDF profile flange connections.
To improve energy efficiency, motors can be speed-controlled.
Motors complying with Ex d, Ex e, Ex nA and Ex tD. Standards can be fitted.
Construction
Galvanised steel housings with 35mm TDF profile flange connections and spun aluminium inlet cone.
Includes backward-curved centrifugal impellers.
Motors
Type - standard TEFC squirrel cage induction motors.
