Cofimco 50F / 50L / 60F Fan

Cofimco · Very low noise, high efficiency

50F / 50L / 60F axial fans

A very low noise, high efficiency fan for air-cooled condensers and cooling towers. It is up to 10 dB(A) quieter than standard fiberglass blades and keeps its efficiency extremely high.

  • Up to 10 dB(A) less noise than standard fiberglass blades
  • From 12 to 40 ft, in standard and reverse mounting
  • Very high resistance to fatigue, using reinforcement ideas from wind turbine blades

How it works

The largest monolithic pultruded blade

The 60F and 50F profiles were introduced to give air-cooled condensers and cooling towers a very quiet fan without giving up efficiency. They are the largest monolithic pultruded blade Cofimco has ever produced.

Compared with standard molded blades, this construction is far more resistant to the fatigue loads and failures often seen around the blade shaft, thanks to reinforcement configurations taken from wind turbine blades.

Hub and installation

  • AX hub made of one steel disc with a connection flange, for easy fitting on the drive shaft
  • Blades fixed with extruded aluminum pillow blocks
  • Gap ring regulator adjusts the fan diameter by 2 inches, to cut tip clearance for more performance or to make up for an imperfect fan ring
