Zodiac - Heat Pump Fan Blade for PX50 (WH000430) - ZX132000015

Zodiac – Heat Pump Fan Blade for PX50 (WH000430)

This is the genuine Zodiac replacement fan blade for the PX50 pool heat pump (model WH000430), listed as position 7 in the official Fluidra exploded-view diagram. The fan blade is a critical rotating component that draws air across the heat exchanger, enabling the unit to extract ambient heat and transfer it efficiently to your pool water. Replacing a damaged or worn blade with this OEM part restores correct airflow and protects the compressor from thermal stress.

Compatibility

This fan blade is designed exclusively for the Zodiac PX50 heat pump, parent model WH000430. The PX50 range features a Full Inverter DC fan motor operating across 10 variable speed levels, so correct blade geometry and balance are essential for quiet, efficient operation. Always verify your unit’s model number before ordering to ensure a precise fit.

Why Genuine Matters

An OEM Zodiac fan blade is engineered to the exact pitch, diameter, and balance tolerances specified for the PX50’s variable-speed DC fan motor. An incorrectly balanced or incompatible aftermarket blade can cause vibration, increased noise, reduced airflow, and premature motor wear — undermining the very efficiency and near-silent operation the PX50 is designed to deliver. Sourcing directly from the Fluidra/Zodiac parts catalogue guarantees part authenticity and traceability.

Installation

The fan blade is accessed by removing the top grille of the PX50 unit. Always isolate electrical power to the heat pump before beginning any work. Secure the new blade to the motor shaft according to the torque specifications in the PX50 installation and service manual, and check for free rotation before powering the unit back on. If you are not a qualified technician, professional installation is recommended to avoid voiding your warranty.
