VAO
Electric motors BAO, VAO2, VAO4, VAO2U, VAO5, VAO7 belong to a series of power units of special design, technically and structurally designed to operate in difficult conditions – in particular, in the presence in the surrounding atmosphere of flammable and explosive substances characteristic of chemical industries, mining, oil refineries, etc. To meet these conditions, special electrical insulating materials and elements that prevent sparking are used in the engine design; the body and the forced-blowing system have a specific configuration. A related feature is increased dust and moisture protection of the housing.
Explosion-proof electric motor BAO2 280 L2 has passed the mandatory state certification and meets all the standards provided for equipment of this class.
