1980’s Mitsubishi Electric Wall Ventilating Fan with 2 Speeds | Exhaust Fan Dinding Jadul

So far, Mitsubishi Electric exhaust fans have really spoiled me as a user, from their quiet operation, strong airflow, to the design that feels distinct compared to other brands. That’s why I couldn’t resist when I found this retro ventilation fan on a marketplace. It came in used condition, but the price was too good to pass up. At first, I thought I’d try swapping it with my EX-30RHK5T, just to see if it might perform even better. The design itself screams late 70s–80s, and judging from the quality and style, I suspect it was made in Japan. When it arrived, I had already expected some parts to no longer be original, and I was right. The switch had been replaced, the indicator was missing, the capacitor had been changed, and there was even a speed-control string (though I’m not sure if it was supposed to have one in the first place). What’s certain is that the string is not original. In terms of build, this fan feels much denser compared to the EX-30RHK5, which already leaned towards using lighter sheet metal and plastics. The louver design is also interesting, almost reminiscent of Sanyo or Maspion 12” exhaust fans, with four separate louvers. Everything still works fine, though not perfectly smooth. Installation was a bit tricky since some screws were sticking out, so in this video the exhaust is only fitted about 75% into the wall opening. It’s still fine, though the back part looks a bit rough with the exposed wall paint around the hole. For this video, I haven’t done any restoration or even lubricated the motor. But since this fan is built like a tank, it still looks and runs decently in whatever condition. Performance-wise, it’s noticeably noisier than newer generations, especially at higher RPM. The airflow is solid, but personally, I prefer the newer models that deliver powerful performance more effortlessly and quietly. I’m not sure if the speed level is due to the replaced capacitor or simply the way this fan was designed originally. Another quirky detail is the 3-speed setting: in exhaust mode, the sequence goes Low–High–Low–Off, while in intake mode it goes High–Low–High–Off. I’m really curious whether this was the original configuration or just the way it was rewired. Maybe someday, if I have the time and motivation, I’ll try tidying this unit up and give it a proper dedicated place.
