Duratech DURAPRO-12 R32 Fan Blade

This genuine Duratech fan blade is a replacement component for DURAPRO-12 heat pump units running R32 refrigerant. The fan blade is essential for maintaining proper airflow across the evaporator coil, enabling the heat pump to extract heat from the surrounding air efficiently.

The Role of the Fan Blade

In an air-source heat pump, the fan blade draws ambient air over the evaporator coil where heat is absorbed by the refrigerant. Consistent, balanced airflow is crucial for the heat exchange process to work effectively. A damaged or degraded fan blade reduces this airflow, forcing the system to work harder and diminishing overall heating performance.

When to Replace

It’s time to consider replacing the fan blade if you notice visible damage such as cracks, chips, or warping, or if the blade has become misshapen due to impact or prolonged use. Operational signs include increased vibration, rattling or wobbling sounds during running, reduced air movement from the unit, or the fan motor working harder than usual. Even small imperfections can create imbalance, placing unnecessary strain on the motor and bearings.

A Manageable Repair

Replacing a fan blade is a relatively straightforward task compared to other heat pump repairs. It typically involves removing the fan guard, loosening the blade from the motor spindle, and fitting the new blade securely. Ensuring correct orientation and tight fitting is important to avoid vibration or noise after installation.
