Centrifugal transport fans WTR
Each housing has an external spiral outline specifically designed by our engineers to optimise the flow.
A standard fan housing is made of welded steel. It is protected against corrosion by paint or galvanisation. Paint coatings protecting the housing are available in the full RAL range of colours.
Asynchronous, in a closed casing made of die-cast aluminium or iron, equipped with maintenance-free bearings, 1 (230V) or
3 (3x400V) phase.
Power supply frequency: 50 Hz.
Insulation class: F or H.
IP 55 protection level.
Operating temperature: -20 to +40 °C.
Optional possibility of operation with a frequency inverter and a higher protection level of IP56 or IP66.
With their robust impeller design, WTR fans are resistant to the instantaneous impact of larger solids. Open impellers are less vulnerable to solid particle deposits on the surface of their blades and any residue is easy to remove.
The impellers of WTR fans have been designed so that controlling wear or damage to the blades is facilitated as much as possible.

** Weight of fans given in this site is the design value and weight of delivered products may be different.
The height of a fan depends on its installation position.
The heights in the table are specified for the selected orientations. The sizes of other installation positions are available on request.
