Tubeaxial Fans

Overview

JM airfoil impellers are high-pressure die cast of aluminum and consist of blades, hub and clamp plate.  The JM 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.
