The new, retrofittable Dplus diffuser is an ideal solution for converting dynamic pressure into static pressure.
Due to the constant cross-sectional expansion, the speed in the direction of flow decreases and the losses are converted into usable static pressure. On the one hand, the gain in static pressure can reduce the fan's drive power, which lowers the fan's operating costs. On the other hand, the gain in static pressure can also be used in such a way that the fan delivers more volume flow with the same drive power. The Dplus is made of 1.5 mm thick sheet steel and is available in three different colours (red, black or white).
Advantages of the Dplus diffuser:
- Optimisation of the flow range
- Conversion of dynamic pressure into static pressure
- Reduce operating costs by reducing the drive power
- Due to the increase in static pressure, the fan can deliver more air volume at the same drive power
- Easy retrofitting to existing fans
- Uncomplicated and quick assembly in a few minutes
You can find a video illustrating the simple assembly on our YouTube channel.
