This is a genuine Bosta replacement fan blade designed for pool heat pump units. Measuring 400 mm in diameter and 118 mm in depth with an 8 mm centre bore, it is engineered for counterclockwise rotation to draw ambient air efficiently across the heat exchanger, keeping your pool heating system performing at its best.<\/p>\n
This fan blade is intended for Bosta-supplied pool heat pump units that require a 400 mm \u00d7 118 mm counterclockwise fan blade with an 8 mm bore. Always confirm your heat pump model and existing fan blade dimensions and rotation direction before ordering, as incorrect rotation direction will prevent proper airflow. Consult your heat pump’s service manual or a qualified technician if you are unsure.<\/p>\n
Sourced directly from Bosta, this OEM fan blade is manufactured to the exact dimensional tolerances and blade pitch of the original part. Using a genuine replacement ensures correct airflow volume, minimises vibration and noise, and protects your heat pump motor from the strain caused by improperly balanced aftermarket blades.<\/p>\n
The 8 mm bore is designed to mount directly onto the fan motor shaft of compatible heat pump units. Secure fitting and correct rotational alignment are critical \u2014 professional installation by a qualified pool technician or HVAC engineer is strongly recommended to avoid motor or heat exchanger damage.<\/p>","protected":false},"excerpt":{"rendered":"
