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 Applications
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.

O
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.
