(1) Exhaust equipment installed on the outside end of a pipe (shaft), most frequently in order to remove impure air from various premises and from railroad cars. Sometimes deflectors are used to bring air into premises, for instance, into a ship. A deflector works by using the energy of air (wind) flowing around it. Deflectors are usually made of sheet metal (steel); concrete, asbestoscement mixtures, and other materials are sometimes used. A deflector must be installed in such a way that the wind will always flow around the deflector regardless of the wind direction; the orifice (mouth) of the pipe must be protected from atmospheric precipitation. The most widely used types of deflectors are the TSAGI (Central Aerohydrodynamics Institute) and Shanar-Etual’ models.

(2) A device for measurement and elimination of deviation in a magnetic compass.
