🌬️ What Exactly is a Lüfter?
A Lüfter is a device used to move or circulate air. Its main purpose is often cooling (Kühlung) (e.g., in computers or engines) or ventilating rooms (Belüftung von Räumen).
It's a technical device, usually electrically powered, that has blades (Flügel) or a wheel (Rad) to create an airflow (Luftstrom).
