Aluminum Centrifugal Impeller | Custom Casting & CNC Machining

This series of aluminum centrifugal impellers is designed for small blowers, cooling fans, vacuum units, and low-pressure pump applications. The backward-/ forward-curved blade geometry moves air efficiently while keeping noise low, and the machined hub bore with keyway mounts directly onto standard motor shafts.

Impellers are produced by in aluminum alloy ?? A356 / ADC12?, then the hub, bore, and blade tips are CNC finished so the assembly runs true at speed. Every impeller is dynamically balanced to, which is what keeps vibration and bearing wear down in customer equipment. Current series covers three diameters — ? Ø90 / Ø110 / Ø130 mm? — and new sizes are made to drawing.

H2: Key Features - Cast aluminum construction: light weight with good corrosion resistance - CNC-finished hub and bore for true running and easy shaft fitting - Dynamic balancing on every piece reduces vibration and noise - Blade count, angle, and inlet diameter configurable to your airflow data - Anodizing or coating available on request

H2: Applications Air blowers and centrifugal fans, air purifiers and cooling equipment, vacuum cleaners, small pumps, kitchen and industrial ventilation units.
