A wide selection of small commercial and residential fans were introduced in the early 20th century. Many of them had the "vane" suffix found on the large models. The Vent Set, which consisted of a direct-connected motor-driven centrifugal fan, moved a large amount of air quietly with a low power input. That made them suitable for ventilating the majority of small rooms where the air was discharged through a pipe.
Westinghouse ended this product line in the late 40s.
