FIELD: technological processes.
SUBSTANCE: invention relates to filter of turbine air intake for removal of particles from air flow at the inlet to gas turbine, which comprises composite filler made of membrane filtering layer, having porous polymer membrane, and at least one layer of volume filtering material. Layer of volume filtering material contains fibers and is arranged at discharge side of membrane filtering layer relative to direction of gas flow passing through filter. Fibers of volume filtering material layer have electrostatic charge. In preferable version of realisation, porous polymer membrane is made of the mixture of homopolymer polytetrafluoroethylene (PTFE) and modified PTFE.
EFFECT: invention makes it possible to reduce dimensions and complexity of filtering system design, to increase its service life and also to develop filter having improved property of water and salt removal.
