I have a similar one, but it is mostly un-useful: for the smoke to be captured by the fan, the fan must be close to the soldering iron, and it will make your soldering job complicated. It will obstruct lighting and movement.
The "professional" systems use flexible pipes coming from a centralized aspirator system. The pipes are smaller and less obstructing.
I once bought a low cost (8 euros?) table lamp, 12 V ac from a transformer in the base , then removed the halogen lamp head and replaced it with a 80 mm pc fan, powered by the transformer, a diode and a series resistor.
It worked better than the dedicated unit (without any filter) to move the smoke away from my eyes and nose...
Sorry, I sold it some times ago, and I have no photos..
