The Sturtevant name was synonymous with large ventilation and especially mechanical draft fans which were essential to the efficient operation of boilers in industrial power plants generating steam for electric power, plant heating and process steam.The "vane" suffix was commonly used with B.F.Sturtevant fans.
First used in the 1920s as a centrifugal fan it later was classified as the Series 7000.
The 7000s were ruggedly built radial tips for handling erosive gases at elevated temperatues and high pressures. Maximum abrasion resistance and minimum stress for rotating parts.
The rexvane was a modern development of the paddle wheel fan. By the use of correct inlet blade curvature and a stream line shrouding, it retained all of the good features of the paddle wheel with greatly increased capacity.
A forwardly-curved fan that was used widely in public buildings, such as hotels, schools and office buildings, for heating, ventilating and air conditioning.
Available as a Design 3(1910 thru early 30s) or Design 6 (early 30s thru the 40s)
Designed for heating, ventilating, air conditioning and industrial applications.
This design was adapted to a wide range of industrial applications requiring high pressure and large volumes at slow rotational speeds.
Dating back to the 1860s, they were designed for collecting and conveying shavings, sawdust, chips, dust from emery and buffing wheels, and similar materials which could be conveyed on a current of air.
The standard version was a 6-blade, steel plate fan(Design 1). In the 1920s two additional "Slow-Speed" types were introduced: 18-blade and 13-blade, forwardly-curved fans(Design 2 and 3). In the late 1930s the tradename Planovane was used.
Wide usages included; conveying granular material, sawdust, long fibrous materials and chips, fume and corrosive gas exhaust and induced draft depending on wheel selection.
Designed to meet a broad range of requirements for rugged, dependable supply or exhaust applications.
