Sturtevant Media - Youtube

Back in 1980 a 9 minute slide show was created by Westinghouse-Sturtevant to present the abilities of the Sturtevant Field Service Department. The first Youtube video combines the audio portion of that presentation with a variety of company imagery.

The other videos were produced by owners of two Sturtevant products.

A nice short video on the operation of the Model 15 Vac with some good close-up shots.
GASOFAN - a sewer fan. In actual operation it would be used as an exhauster with a canvas hose connection at the outlet to direct away the fumes.
