Aluminum Impeller
Shrijee Nut Company's Aluminum Impellers are precision-cast, dynamically balanced fan impellers designed for use in industrial blowers and centrifugal fans throughout peanut and food processing facilities. Manufactured from high-grade aluminium alloy, these impellers combine lightweight construction with high strength and corrosion resistance for demanding industrial air-handling applications.
Each impeller is precision-balanced to ISO G6.3 or better standards, ensuring smooth, vibration-free operation that extends bearing and motor life while minimising noise levels in the processing environment.
Aluminum Impellers by Shrijee Nut Company are high-quality replacement and OEM impellers for centrifugal fans and blowers used in peanut processing operations. Cast from LM6 or equivalent high-silicon aluminium alloy, they offer an excellent combination of light weight, high strength, and natural corrosion resistance — ideal for food processing air-handling equipment.
Available in forward-curved, backward-curved, and radial blade profiles to match different pressure and flow characteristics, each impeller is supplied dynamically balanced to minimise vibration and extend the service life of the blower assembly.
- High-grade aluminium alloy (LM6 / equivalent) construction
- Dynamically balanced to ISO G6.3 standard
- Available in forward, backward, and radial blade profiles
- Custom sizes from 200 mm to 1200 mm diameter
- Compatible with major blower brands and custom installations
Lightweight Aluminium Alloy
High-grade aluminium alloy construction delivers significant weight savings over steel alternatives, reducing motor load and energy consumption in blower systems.
Dynamic Balancing
Each impeller is dynamically balanced to ISO G6.3 or better, eliminating vibration that causes premature bearing failure, motor damage, and structural fatigue.
Corrosion Resistance
Natural aluminium oxide layer provides excellent corrosion resistance in humid food processing environments, extending impeller service life without special coatings.
Multiple Blade Profiles
Forward-curved, backward-curved, and radial blade profiles available to optimise airflow, pressure, and efficiency for different blower applications in processing lines.
Precision Cast Construction
Precision sand or die casting process ensures accurate blade geometry and consistent performance across all impellers within a production batch.
Custom Size Availability
Available in diameters from 200 mm to 1200 mm with custom bore, key, and hub configurations to match existing blower shafts and housings.

Reduced Energy Consumption
Lightweight aluminium construction reduces rotational inertia, requiring less motor power compared to steel impellers for equivalent airflow output.
Long Service Life
Corrosion-resistant aluminium alloy and dynamic balancing extend impeller service life, reducing replacement frequency and associated downtime costs.
Vibration-Free Operation
ISO-standard dynamic balancing eliminates vibration that causes bearing failure and structural fatigue, ensuring reliable, quiet blower operation throughout service life.
Application-Specific Customisation
Custom diameters, blade profiles, hub configurations, and bore sizes ensure a perfect fit for any existing or new blower installation in peanut processing facilities.
