Axial fans are the end product of many years of fan development in our American Fan Company engineering laboratories. They encompass design features derived from experience, techniques borrowed from Airbus design, computer simulation, and customer input. Axial fans are available in both direct drive and belt drive.
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.
