JM aerofoil impellers are high-pressure die-cast of aluminium 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, before machining to assure casting integrity and quality. Impellers are precision balanced as a fan assembly to minimize vibration levels and assure smooth operation.
