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.

Typical Application
Commercial and industrial supply or exhaust applications requiring higher pressures for air filtration or long duct runs. These applications include shopping centres, office buildings, exhibition centres, hotels, health centres, schools and universities.

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.
