Fairbanks Morse Defense Acquires American Fan
FMD adds state-of-the-art axial fans and centrifugal blowers to its growing portfolio of OEM equipment.
Manufacturing Innovative & Practical Fans and Fan Systems
Fairbanks Morse Defense and American Fan provide air movement solutions with Axial Fans and Blowers for industrial, commercial and marine/offshore applications worldwide. We are the primary supplier of shock-qualified fans for U.S. Navy surface ships, and its products and services are specified in 30 U.S. Navy shipbuilding programs, including LCS, LPD, LHA, DDG, and FFG. We understand the needs of the modern marine and naval industry, and the requirements of the consulting engineers and contractors who serve it.
AXIAL FANS
Axial fans have been designed from experience and techniques borrowed from the Airbus design, computer simulation, and customer input. Axial fans are available in both direct drive and belt drive.
The axial flow fan involves the motor spinning blades around a hub, which moves air parallel to the axis of rotation. This type of blower is primarily used in ventilation systems.
Airfoil impellers are high-pressure die cast of aluminum and consist of blades, hub and clamp plate. The impeller is manually adjustable through the full range of pitch angles. All impeller components are X-rayed using real time radiography, and examined to ASTM E-155, prior to machining to assure casting integrity and quality. Impellers are precision balanced as a fan assembly to minimize vibration levels and assure smooth operation.
Fan casings are made of heavy gauge steel with spun flanges and continuously welded seams. The casing is manufactured to a stringent tolerance for roundness, which assures proper blade tip clearance for optimal performance.

CENTRIFUGAL FANS/BLOWERS
A centrifugal blower uses centrifugal forces to rotate the blades. 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 outlet flanges with mounting holes and continuously welded are standard. They 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 comply with the requirements of the AMCA Certified Ratings Program.
