FIELD: fire-fighting equipment.
SUBSTANCE: invention relates to a flame arrester for preventing the spread of fire in industrial communications, comprising a metal housing configured to be flanged to a pipeline, with a metal grid installed inside the metal housing, besides, that metal grid is formed by metal brushes installed in staggered order in side walls of metal housing, wherein brushes are made with possibility of friction against each other and rotation due to the rotation of the electric drive located outside the metal housing and connected to the brushes by connecting chains fixed on the gears connected to the brushes axes and located outside the metal housing, note here that gate valve is arranged in metal case bottom to remove sediment.
EFFECT: use of a fire arrester enables to prevent the spread of fire in the ventilation system; reduce hydraulic resistance due to cleaning of metal grid; higher efficiency and longer life.
