​How to Select Centrifugal Fans for Different Applications?

Those familiar with fans generally understand that when choosing centrifugal fan equipment, performance may vary depending on the specific operating environment. For instance, when using centrifugal fans in warehouses, key considerations during procurement include whether the stored goods are flammable or explosive materials—such as in paint warehouses—necessitating the selection of explosion-proof centrifugal fans. Of course, when selecting centrifugal fans for warehouses, operational noise levels must also be considered. Additionally, the required ventilation volume for the warehouse air must be assessed to choose the appropriate fan equipment. Many users also seek solutions for kitchen exhaust requirements. For kitchens with direct indoor exhaust of cooking fumes, where the exhaust outlet is on an interior wall, selection should be based on the volume of fumes generated. For instance, kitchens with heavy fumes requiring passage through long ducts with bends should use 4-72 centrifugal fans or low-noise centrifugal fans. What type of fan should be selected for ventilation in venues like hotels, teahouses, cafes, card rooms, and karaoke halls? If the indoor space is relatively small and connected to a central ventilation duct via a single vent pipe, compact centrifugal fan units with plastic or aluminum exteriors can be chosen. These meet aesthetic and noise requirements while ensuring ventilation quality and minimizing operational noise. Of course, if higher airflow capacity is needed, larger centrifugal fan units should be selected, primarily considering appearance and safety aspects.
