I have a ventilator fan like the above (230V, 50hz, 38 watt) - very electronic with 3 speeds, swing function, nature function etc.
Sometimes the lowest rotational speed is too fast; can I add a normal dimmer switch inline?

Can you? That would depend on your skill level, but keep in mind that dimmers are not for controlling motors and are just for use on lighting. A dimmer could potentially damage the motor and will probably burn up quickly in trying to control a motor. It's not a smart thing to do.

You could try a speed controller for hand tools but I can't say how well it would work. Example: Router Speed Control

We have plug in speed controllers here in the States like Ray illustrated but you'll need something for 230v. I didn't see any plug in type models. I did see many controllers on eBay/UK that would work but are not necessarily the safest idea.
