When shopping for centrifugal fans, it's easy to use many common buying phrases like" " and centrifugal blowers." Although both of these descriptions are technically accurate, they are not exactly what they sound like. In fact, the two most often-used term phrases are "blower" and "centrifugal fan." So why do you hear both terms when shopping for a fan or blower? While a blower can be considered as a more powerful version of a centrifugal fan, the term "centrifugal fan" is actually the correct term to use.
