International Environmental 70005122 Blower Wheel

As a seasoned technician, you know that maintaining precise airflow in International Environmental Corporation (IEC) systems is non-negotiable. The International Environmental 70005122 Blower Wheel is a critical OEM replacement part engineered specifically for high-performance fan coil units and industrial ventilation assemblies. This double-inlet centrifugal wheel ensures the static pressure requirements of your HVAC system are met without stressing the blower motor.

The IEC 70005122 features a 9-inch diameter and a 10-inch width, designed with a 0.50-inch bore to seat securely on standard motor shafts. Constructed from heavy-duty galvanized steel, this blower fan blade assembly is precision-balanced to eliminate the vibration and harmonic noise often found in generic aftermarket alternatives. With a CCW (Counter-Clockwise) rotation, it integrates seamlessly into IEC model 90000400 housings, providing the consistent CFM delivery needed for demanding commercial environments.

Key Benefits for the Contractor:

• Direct OEM Compatibility: Engineered as a drop-in replacement for IEC part number 70005122, ensuring proper alignment and housing clearance.
• Reduced Mechanical Stress: Precision balancing prevents shaft run-out, protecting your blower motor bearings from premature wear.
• Optimal Air Handling: The specific fin geometry is designed to maximize HVAC airflow efficiency in forced-air applications.
• Rugged Build: Corrosion-resistant materials withstand the high-humidity conditions typical of commercial air handling units.
