COMEFRI blade profile, covering diameters up to 4800 mm, has been developed and tested in our AMCA certified laboratory, in accordance with AMCA 210 and AMCA 300.
The main characteristics of our profile are:
- High static pressure
- Low tip speed
- Narrow chord design with reduced clearances
- Low noise levels
Blades are made in extruded anticorodal and anti-sparking aluminium alloy, with shafts and hubs in galvanized carbon steel or stainless steel (on request).
The impeller can be assembled with different numbers of blades and pitch angles, allowing to optimize the selection.
COMEFRI can provide both the impeller and the complete fan (impeller + short/long casing), equipped with a wide range of accessories.
Typical applications:
- Marine & Offshore
- Air cooled heat exchangers
- Cooling towers
- Power generation plant
- Cement plant
- Industrial process
- Evaporative condensers
