B,  Centrifugal Compressor


A process machine whose primary function is to provide a large flow of air or gas to various processes. The blower works by rotating a centrifugal impeller connected to a shaft that is driven by a motor or turbine. A blower differs from a fan in that it operates where the resistance to the flow is primarily on the downstream side of the fan. This requires blowers to generate more pressure than fans.

Compare to Fan.
