Axial fan airfoil high efficiency

H Series axial fans

Fan design features:

  • 5 fan blades of different profile design and sizes.
  • 2 to 14-blade configurations for axial fans.
  • 6 available hub sizes – 3, 6, 8, 10, 12 and 14 blades.
  • Available in a range of bore/fixing configurations.
  • 6 standard pitch angles ranging from 25º to 50º in 5º increments.
  • Diameter range from 225 mm up to 742 mm.
  • Fan blades for both clockwise and counter-clockwise rotation.
  • Replacement fan blades available.

The H Series represents the smallest diameter fans in the Multi-Wing product line and covers diameters from 225 mm up to 742 mm. As with all Multi-Wing fans, the H series is designed to have high efficiency and low noise levels and to be corrosion resistant. It is robust yet light-weight, resulting in less wear and stress on motors and bearings. Its compact but solid design is well suited for a wide range of applications and is available in 2- to 14-blade configurations in pitch angles from 25º to 50º in 5º increments. For engine and compressor cooling this fan type offers a flexible solution that will meet all dimensioning criteria - especially when noise levels are critical. Type H is also applicable to agricultural ventilation, which calls for high performance at low static pressure. For refrigeration applications, this type is often used in evaporators and in smaller condensers.

Fan materials:

Four posts and a rectangular base distinguish the H Series blade root and the H spacer. The hub parts are as standard manufactured in a pressure die cast silumin alloy (EN AC-Al Si12 Cu1 (Fe)). The 6 and 8-blade hubs are also available in a version manufactured in glass reinforced polypropylene (PPG), whereas the 3-blade hub is only available in a version manufactured in glass reinforced polyamide (PAG).The fan blades are available in the following 5 materials to suit applications with different speeds and ambient temperatures: PPG, PAG, PAGASPAGST and AL.
