JM AerofoilJM aerofoil® 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.
