When space is short, weight must be kept down and you're in need of some serious ventilation this little beauty could be the answer.
At just 48mm diameter and 60mm long it can be mounted directly behind one of our eyeball vents.
These incredible little 12 volt fans blast a massive 22 cfm air flow.
They're made in Switzerland to very high engineering standards, so cheap they ain't.
