I used to use a Von Schrader machine that was similar but the foam was a much different consistency.
The VS foam was really thick (and "dry"), even thicker than shaving foam out of the can. We were taught to vac it of immediately.
Things could be touch dry in a few minutes and so it was great for say coaches or cinemas where you needed quick turnaround and drying.
