In 1906, Sturtevant installed the first industrial air conditioning system at Walter Baker & Company in Dorchester, and, at a Chicago hotel in 1910, the first residential air conditioning system. Beginning In 1911, Sturtevant Manufacturing Co , produced several aircraft engines, before being absorbed by the B. F. Sturtevant Company. [ 2 ]
A centrifugal fan is a mechanical device for moving air or other gases in a direction at an angle to the incoming fluid. Centrifugal fans often contain a ducted housing to direct outgoing air in a specific direction or across a heat sink; such a fan is also called a blower, blower fan, or squirrel-cage fan (because it looks like a hamster wheel).
In 1875, Roots exhibited a blower at the Saint Petersburg Exhibition; Thwaites and Carbutt exhibited a Roots principle "air blowing machine" for mine ventilation in the same exhibition. [6] In 1885, Edgar Dwight Johnston joined the firm of 30 people; he became vice president in 1889 and president in 1898, remaining so until at least 1931.

A centrifugal fan produces more pressure for a given air volume, and is used where this is desirable such as in leaf blowers, blowdryers, air mattress inflators, inflatable structures, climate control in air handling units and various industrial purposes. They are typically noisier than comparable axial fans (although some types of centrifugal ...
An Eaton M62 Roots-type supercharger is visible at the front of this Ecotec LSJ engine in a 2006 Saturn Ion Red Line.. The Roots-type blower is simple and widely used. It can be more effective than alternative superchargers at developing positive intake manifold pressure (i.e., above atmospheric pressure) at low engine speeds, making it a popular choice for passenger automobile applications.
Blower door tests are used by building researchers, weatherization crews, home performance contractors, home energy auditors, and others in efforts to assess the construction quality of the building envelope, locate air leakage pathways, assess how much ventilation is supplied by the air leakage, assess the energy losses resulting from that air ...
A leaf blower, commonly known as a blower, is a device that propels air out of a nozzle to move debris such as leaves and grass cuttings. Leaf blowers are powered by electric or gasoline motors . Gasoline models have traditionally been two-stroke engines , but four-stroke engines were recently introduced to partially address air pollution concerns.
