SUBSTANCE: double air screen includes air lock, air risers in air lock opening and in gate of building, fan with heater of inner screen and fan of outer screen. Air to risers of outer screen is fed by means of fan of general exhaust ventilation system form working area. Risers are located at air lock inlet. Air lock may be stationary of mobile. It is provided with double elastic walls. In this case, motion of outer risers is effected over guides, for example over rails as double elastic walls get filled with air.
