Axial

 

 

COMEFRI blade profile, covering diameters up to 4800 mm, has been developed and tested in our AMCA-certified laboratory, by 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 anti-corodal and anti-sparking aluminum 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
Diameter Max Performances
500 ÷ 1250 152.000 m³/h or 2.000 Pa
1400 ÷ 2450 280.000 m³/h or 1.500 Pa
2150 ÷ 4900 595.000 m³/h or 870 Pa
Please note that, for sizes below 800 mm, the blades are in die-cast aluminum.
