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.
