Panaflo Fan Spec question

[Serville]

Does someone knows what this "Variable speed" means in DC fan ?

I bought a Panaflo 60x60mm fan model: FBA06A12V , 0.3A. (look at the ending code V)
But surprisingly this fan is so weak. I guess it is only around 12-14 CFM although it takes 0.3A of power !!!
Looking into Panaflo's Product Designation Code for this fan, they say the ending code in the model number refers to the fan speed as follows:

L ---> Low , M---> Medium, H ---> High, U ---> Ultra High, V ---> Variable (option)

So the fan speed of my model is said to be "Variable (option)". What this actually means ???

The fan takes 0.3A but the power is even weaker than the M model (0.13A, 16.6 CFM).
Does it mean I can set my own speed in this "Variable (option)" model ?
Anyone understands what this spec actually means ?

Say Serville, does that fan have 3 wires? are there any more numbers or letters in the designation code on the fan?

If you left off "1C" from the end of the desig.code you probably have a '3rd lead thermo sensor' model!

Looks like you have a fan that will run a different speeds dependent on the temperature that is sensed! I have a couple of 120mm NMB fans with a thermal sensor, but they just turn-on when the temp is reached (not variable speed).
Where did you purchase that fan? I would be interested in purchasing a few for one of my boxes.
