A centrifugal fan is a mechanical device for moving air or other gases in a direction at an angle to the incoming fluid. Centrifugal fans often contain a ducted housing to direct outgoing air in a specific direction or across a heat sink; such a fan is also called a blower, blower fan, or squirrel-cage fan (because it looks like a hamster wheel).
Mechanical vapor recovery blowers-These specially designed centrifugal fans are designed to increase temperature and pressure of saturated steam in a closed-loop system. Acid gas blowers - These very heavy construction blowers are suitable for inlet pressures from full vacuum to 100 psig. Materials are selected for corrosion resistance to the ...
A centrifugal fan produces more pressure for a given air volume, and is used where this is desirable such as in leaf blowers, blowdryers, air mattress inflators, inflatable structures, climate control in air handling units and various industrial purposes. They are typically noisier than comparable axial fans (although some types of centrifugal ...
Elektrobau Mulfingen GmbH is the parent company of the ebm-papst Group, a manufacturer of electric motors and fans.The group was formed in 2003 from the merger of the companies Elektrobau Mulfingen GmbH & Co. KG (ebm), Papst Motoren GmbH and Motoren Ventilatoren Landshut GmbH and operates international production sites (including in Germany, China and the United States).
The centrifugal force imparts static pressure to the air. The diverging shape of the scroll also converts a portion of the velocity pressure into static pressure. [citation needed] There are three main types of centrifugal fans: Radial-blade fans - Radial-blade fans are used for heavy dust loads.
An Eaton M62 Roots-type supercharger is visible at the front of this Ecotec LSJ engine in a 2006 Saturn Ion Red Line.. The Roots-type blower is simple and widely used. It can be more effective than alternative superchargers at developing positive intake manifold pressure (i.e., above atmospheric pressure) at low engine speeds, making it a popular choice for passenger automobile applications.
