Case study

Double-inlet centrifugal fans with backward-curved blades used for spray booth air extraction

A customer of our client wanted to install a new spray booth to be able to finish their products with the latest technology again. Here, of course, it is important to use a suitable ventilation system, such as double-inlet fans. To develop a good ventilation system, several factors need to be considered. One of these factors is the size of the spray booth and the volume that needs to circulate through it. The ventilation system must be able to effectively remove the air pollutants produced, such as paint mists and toxic gases, while ensuring air quality. Because of the toxic gases, the solution also had to comply with Atex guidelines. This is why we chose double-inlet centrifugal fans. Read more about this under the heading “solution”.
