FIELD: machine building.
SUBSTANCE: compressor block (1) contains electric engine (2). During operation rotation axis (60) is directed vertically, while case (4) has drainage (64) on axial end (63) positioned beneath. The same technical result is achieved in the procedure of assembly of compressor block (1), when first it is filled with non-compressed medium above surface of water and then transported to a place of operation under water; branches are connected to inlet (6) and outlet ports and medium is withdrawn from compressor block (1) through drainage (64).
EFFECT: avoiding liquid corrosive medium influence at under-water operation.
