A centrifugal blower uses a motor to rotate the bladed impeller within a scroll or housing. The flow of air or gas is moved around a fixed point, allowing sediments in the air to be caught. This very fact makes them great for pollution control, but they also serve as a high-pressure cooling mechanism.

American Fan’s range of centrifugal fans consists of fans for general air movement, emergency smoke extraction, and in the United Kingdom, ATEX explosive atmospheres. One piece or continuously welded outlet flanges with mounting holes and continuously welded are standard. Industrial centrifugal fans are designed with eccentric or spring lock bearings for positive bearing to shaft locking. Narrow width fans, unitary bases, and all arrangements are pre-engineered for lead-time reduction.

We certify that the centrifugal fan models BCA, BCS, QBCA, QBCS, are licensed to bear the AMCA seal, based on tests and procedures performed in accordance with AMCA 211 and AMCA 311 and to also show compliance with the requirements of the AMCA Certified Ratings Program.
