FIELD: transport.
SUBSTANCE: invention relates to divers' breather with air feed from the surface. Portable breather comprises at least two compressors with electric drive and surface inlet, vessel connected with compressor outlets, storage battery with output terminals connected visa pressure relay outputs with two compressors. It comprises surface inlet, hose with inlet connected with vessel connected with compressor outlet, hose, breathing mechanism kept by diver mouth and connected with hose. Proposed breather comprises second pressure relay with its inlet connected with vessel opening and normally closed output contacts connected with outputs of two compressors. At the same time, at closed contacts, pressure relay has its output contacts connected with outputs of two compressors.
EFFECT: higher reliability, improved conditions of operation, compact design.
