Propeller Fan Blades PDF Print E-mail

Fans are balanced in both length and width to eliminate vibration and provide a long life.

Our highlights:

  • The propeller is a one piece structural polyurethane foam core and fiberglass propeller. Most competitors have several components, of which 2 or 3 blades. This makes it impossible to align them perfectly. As a result, vibrations may occure, bearings brake down, welding joints rupture etc.
  • Stiffer blade. Therefore no waste of horsepower.
  • The useful airfoil of the blade is 20% longer than the competition.
  • Donier swept tips are used on the end of the fan to reduce drag and smooth out the air turbulence and vortices that builds up at the ends of the fan blade. This improves the air flow efficiency over the entire blade.
  • The sector angle coverage is 80°, compared to 45-47° coverage of other fans. The 80° sector coverage works not only on the horizontal plane, but also on the vertical plane by reaching higher up in the atmosphere, pulling down much more warmer air. (see picture below)
  • There is a 60 second duration of air movement versus 35 seconds at the competitors.
  • The volume of air produced is 2.2 times better than the competitors.
  • Our propeller is hallowed, so much lighter. The weight is 2 to 3 times less than from the competition. Therefore, less horsepower needed, which saves on fuel.
