19th century air conditioner used in hot climates

Can you guess what this unfamiliar antique was used for? It is 40 inches high and 35 inches wide and probably made of Southern Yellow Pine.

It is called a “punkah.” It was made in the early 19th century and used with the help of a man called a “punkah wallah” who pulled a cord to make the punkah swing back and forth like a fan. It was the “air conditioner” used in hot climates, not just in America.
