FlowGrid stands for efficient noise protection features in cooling, ventilation and air-conditioning technology. ebm-papst offers a future-oriented solution for the problem of high-performance technology generating disturbing noise: FlowGrid for centrifugal plug-fans.
The grille on the air-inlet side drastically reduces the noise emissions and minimises disturbing low frequency tones.
There are often problems wherever people and technology share space. The movement of air, for example, often goes hand in hand with noise. With FlowGrid, noise-generating disturbances in the fan inflow are a thing of the past!

With FlowGrid, ebm-papst is making a clear contribution to active noise reduction (less noise - more quality of life). The innovative air-intake grilles work with both axial and centrifugal fans whilst not affecting their high efficiency in any way. Using them can help to reduce or entirely avoid the use of cost-intensive, passive noise-reduction measures.
The measurement results detailed below show the benefits that FlowGrid can offer.

Central ventilation and aeration of rooms, with or without heat recovery and outside air treatment.
Apart from the fans, components such as filters, heat exchangers, humidifiers and de-humidifiers are installed in the device. The fans press air through the device and then through ventilation ducts.
Significant turbulences at the fan inlet, due to low distances between the fan and the walls in the intake area, as well as components of the device, impede the flow of air.
Benefits of FlowGrid
Reduction of the noise level by 3.3 dB(A) and of the blade-passing noise by 9 dB, reducing the need for acoustic insulation.
