Axial Fans.

Axial fan Selection program and curve plotting software customised to suit your own fan designs.

The Axial Selection program is an axial fan software package for selecting and plotting axial fan performance.
The program can interpolate between pitch angles and dynamically plot the interpolated pitch.
Different diffuser efficiencies and sizes can be used in the selection process to produce new fan performance curves.

The program is supplied with the FVA fan already installed to demonstrate the programs features.

FVA Fan

The Fva fan is a high efficiency design based on free vortex flow theory.

Large scale models of the design have been tested and other sizes and hub ratios are obtained by scaling in accordance with the fan laws.

The performance is adjusted for different diffuser efficiencies and sketches provided of the overall fan dimensions.

H & R Resources can provide detail drawings and engineering calculations such as blade natural frequencies and stresses to suit any application for the FVA fan.
