Sturtevant Forwardly Curved Fan

Product Catalog > Large Fans > Forwardly Curved Fan Forwardly Curved Draft Fan Sturtevant's switch to straight from spooned blades in the 1930's was based on two facts: 1) The hot-forming required to create the spooning added an additional layer of cost and 2) The depressions caused a long-term structural weakness in the blades.
