Diversitech a61955 Aluminum Fan Blade 3.5 in 10 Blade Cw

Product Description

The DIVERSITECH a61955 is a small aluminum fan blade designed for ducted HVAC and ventilation applications. With a 3.5-inch diameter and a 0.25-inch bore, this 10-blade wheel moves air efficiently in compact fan assemblies. The clockwise rotation designation is critical for proper airflow direction, so confirming motor shaft rotation before installation is essential. HVAC technicians and service professionals install this blade type as a direct replacement in small blower and fan applications where precise blade count and bore size must match the original equipment.

This fan blade is suited for ducted residential and light commercial HVAC systems requiring a compact, low-profile fan wheel. Its aluminum construction keeps weight low while providing adequate rigidity for continuous-duty fan motor service. Typical installation scenarios include small evaporator fan assemblies, equipment cooling fans, and similar forced-air applications where the 3.5-inch diameter and 0.25-inch bore meet the original design specifications.

Key Features

• Aluminum construction for lightweight, corrosion-resistant performance in continuous-duty service
• 10-blade design provides balanced airflow in compact fan assemblies
• 3.5-inch diameter fits small fan motor applications
• 0.25-inch bore for direct shaft mounting on compatible motors
• Clockwise (CW) rotation for correct directional airflow in ducted systems
• Suited for ducted HVAC and ventilation equipment

Compatibility

Designed as an OEM-style replacement fan blade for ducted HVAC and ventilation equipment requiring a 10-blade aluminum wheel with a 3.5-inch diameter and 0.25-inch bore in clockwise rotation.

Installation Notes

A licensed HVAC technician should disconnect and lock out power to the unit before removing or installing any fan blade. Confirm motor shaft rotation direction before mounting to ensure the clockwise blade orientation aligns with the system airflow requirements. Secure the blade firmly to the motor shaft set screw or hub to prevent slippage under load. Follow all applicable local mechanical codes and manufacturer service guidelines during installation.
