Manufacturing Innovative & Practical Fans and Fan Systems

Fairbanks Morse Defense and American Fan provide air movement solutions with Axial and Centrifugal 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 our products and services are specified in 30 U.S. Navy shipbuilding programs, including DDG, LPD, LHA, FFG, and LCS. We understand the needs of the modern marine and naval industry and the requirements of the consulting engineers and contractors who serve it. Additionally, our industrial centrifugal fans meet the needs of customers in a wide variety of industries, including but not limited to, aviation support, boiler/furnace, transit, conveyance and textile. 

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 rotating a hub with blades mounted to or cast into it, which moves air parallel to the axis of rotation. This type of blower is primarily used in ventilation systems.

Navy Axial impellers are cast of aluminum that are not adjustable. These undergo stringent controls and inspections. 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. All impellers are precision balanced as a fan assembly to minimize vibration levels and assure smooth operation.

Axial fan casings are made of heavy gauge steel with flanges and 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 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.
