Historical Minute - May 2013
“Until recently…it was the practice, in the equipment of theatres, to install one or two noisy exhaust fans and spot a few gas radiators throughout. When the combination of garlic, Fleur de l’Orient, halitosis, etc. became unbearable, the organ and the big propeller fans would be started.”
“Some of these old propeller fans are quite the equal of the organ in noise-generating characteristics, but they move the air out, and down the aisles comes a flood of cool air, striking the defenseless patron on the back of his perspiring neck and legs. Naturally, we are behind in our hospital building program.”
—“Don’ts on Theatre Ventilation” by E. Vernon Hill, The Heating and Ventilating Magazine, March 1925.
