Packard A61103 Fan Blade

The Packard A61103 is a precision-engineered 7-inch aluminum fan blade designed for high-efficiency heat transfer in small-scale HVAC and refrigeration systems. This 5-blade hubless propeller features a 25-degree pitch, optimized for moving consistent air volumes in condenser or evaporator applications where space is restricted. Engineered for CW rotation (clockwise), this one-piece propeller is a common replacement in reach-in coolers and small exhaust units. The hubless configuration allows for versatile mounting on compatible motor shafts, ensuring a secure fit and reduced vibration during high-RPM operation. Using high-grade aluminum fan blade construction, this component resists corrosion and maintains structural integrity under thermal stress. When performing a Packard A61103 cross reference, technicians must verify that the 25-degree pitch and clockwise rotation align with the OEM motor specifications to prevent amperage spikes or motor burnout. This replacement HVAC fan blade provides the balance and aerodynamic profile required for quiet, reliable airflow.

• Universal Hubless Design: Allows for flexible installation on various shaft diameters using compatible hub adapters.
• Corrosion-Resistant Aluminum: Ensures longevity in high-moisture refrigeration environments and outdoor condenser units.
• Optimized 25-Degree Pitch: Delivers the ideal static pressure and CFM ratio for small-diameter cooling applications.
• Precision Balanced: Reduces mechanical wear on motor bearings by minimizing harmonic vibration during operation.

Common Questions

How do I determine the rotation for the Packard A61103?
This blade is rated for CW (Clockwise) rotation. To confirm, view the blade from the discharge side (the side air is blowing toward) to ensure the lead edge of the blade matches the motor's rotation direction.

What motors are compatible with a hubless fan blade?
As a hubless propeller, the A61103 requires a separate hub or a motor with a compatible mounting surface. It is frequently used with unit bearing motors and small fractional horsepower motors found in commercial refrigeration.

Can this blade be used in both evaporator and condenser applications?
Yes, provided the 7-inch diameter and CW rotation match the system requirements. Its aluminum construction makes it suitable for both cold, damp evaporator coils and warm condenser environments.
