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 axial and centrifugal 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...

Noise disturbance – cause and solution. Situation. Excess noise is the result of the inflow of air to a fan being disturbed. Asymmetrical suction conditions, such as the walls of a device being at different distances from the fan, create powerful vortices. In the narrowest areas, these combine to form so-called vortex strings. These turbulences then hit the rotating blades of the fan, generating noise – specifically a broadband noise and additional narrowband, tonal frequency components, known as propeller noise or tonal noise. Noise spectrum. Formation of air vortices due to an...

As a global player, we have to consider global issues. This also includes acting in an environmentally-conscious way. An important part of this is the reduction of noise, which plays a major role in regard to general quality of life. With FlowGrid, ebm-papst is making a clear contribution to active noise reduction. 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. It is no surprise then that FlowGrid has...

Axial applications Air-water heat pump with HyBlade® 0 630 Condenser with HyBlade® 0 710 V-shaped condenser with HyBlade® 0 800 Condenser with HyBlade® 0 800 and AxiTop Function Heat is extracted from the outside air. This is used to heat the residential building via a circulatory system. Design The axial fan is installed directly behind an evaporator for horizontal or vertical air conduction. Challenge In compact heat pumps, the evaporator is placed very close to the fan. Excess noise is created by the installation position. As heat pumps are used in residential buildings, however,...
