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.
