ebm-papst has launched a diffuser that it says is setting a new standard in terms of acoustics, efficiency and flexibility.
The AxiTop can significantly increase fan performance while reducing operating noise. Its pressure-boosting effect minimises 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.
The AxiTop diffuser configuration can be optimised 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 per cent 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 nine per cent 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.
