SPAL brushless 16” cooling fan test 30107101

SPAL aftermarket brushless 16” fan 30107101

Fan part number VA117-ABL506P/103A

500w brushless motor, 16” blade tip to tip, 16.5-17” hole, drop in installation 2.25” depth under mounting flange and 3/4” above mounting flange.

Running this on a eBay PWM+ generator 100hz, fan starts at 15% and full speed at 90%. fan shuts down at 98%. Here is some flow data on a HOWE dual core 1” tubes aluminum aftermarket radiator. Anemometer is only showing airflow and speed through this rad in my conditions and are not accurate CFM numbers.

15% = 1.67amps/22.5w and 846ft/min
30% = 3.72amps/48.8w and 1259ft/min
50% = 9.21amps/119.4w and 1771ft/min more air than flexalite and almost as much as procomp at 50%. Look at the wattage 194w brushed for 119w brushless and about 5amps less
70% = 19amps/242w and 2302ft/min
90% = 34.2amps/425w and 3109ft/min 35.1mph
