Hi there, has anyone installed the propeller type of ventilation fan onto their plaster ceiling before? Kindly refer to below pic. From what I found out, this type of ventilation fan doesn't connect to a ducting hose.

I am thinking of installing one near to my altar.
My concern here is the condition of the plaster ceiling after a few years of having trapped incense smokes and dust inside. Has anyone done this before?

The reason why I can't go for the modern type with ducting hose like Tuma and Airegard is because the depth of my plaster ceiling is low and also I can't hack my walls anymore.

Ventilation w/o vent is called tupperware.
Most ppl mount that 6in propeller fan on the window. Or you can install the typical 10in exhaust fan and board up the rest of the window with clear plastic, this work much better for drying the bathrooms.
