Multi-Wing's Engineering Guidelines

The Multi-Wing Engineering Guide provides a comprehensive engineering overview of the Multi-Wing System. The Guide also includes essential design principles that can assist you in achieving the maximum efficiency, performance, and lowest noise levels in your application.

Fan Laws

When the working conditions differ from those stated on the performance curves (speed and diameter), adjustment should be made using the following formulae before reference to the performance curves.

Contra-Rotating Two-Stage Axial Impellers

When a high static pressure is needed a configuration of two counter rotating impellers is often an overlooked solution.

Field Study of Performance and Noise for TR7Z

Our field tests show that the TR7Z impeller provides real efficiency advantages that can be translated into energy savings in wood drying applications.
