ebm-papst: Centrifugal fans for AHUs usually the better choice

When it comes to fans, it is not easy to decide which actually has the best degree of efficiency and works with the greatest possible energy efficiency. The complex flow machines react to every change in the installation situation, speed variations, or changed pressure conditions. Centrifugal fans are the better choice for AHUs. But why? Centrifugal fans (image, left) ensure a more uniform application of air to downstream components (filters, heat exchangers) than axial fans (image, right). The axial speed is presented in color.
