AxiTop diffuser by ebm-papst: Listen to the difference

ebm-papst has developed a diffuser that is setting a new standard in terms of acoustics, efficiency and flexibility. The AxiTop can significantly increase fan performance while reducing operating noise. It can easily be retrofitted on existing installations without redesigning the customer's application.

The AxiTop can significantly increase fan performance while reducing operating noise. Its pressure-boosting effect minimizes exit losses and makes it easy to adapt the fan to commercially available heat exchangers. The combination of internal and outer diffuser is a worldwide innovation and was developed to fit the company’s HyBlade axial EC fans in sizes 800mm and 910mm. The AxiTop reduces the velocity in the airstream, converting dynamic pressure into static pressure in a more efficient and quieter way.

Main benefits: greater efficiency, less noise, reduced exit losses
The AxiTop diffuser configuration can be optimized for different characteristics, depending on the application concerned. It is possible to either achieve lower energy use or get greater air performance with unchanged energy input. Both settings also reduce the fan’s noise level.

If set to efficiency, up to 27% less power use can be achieved, along with a reduced operating noise level of up to 7.2 dB(A).

On the other hand, if set to performance, the AxiTop can provide up to 9% more air flow while still reducing noise emissions by 4.9 dB(A) with the same connected load.

It can easily be retrofitted on existing installations without redesigning the customer's application.
