Abstract

PURPOSE: To prevent infiltration of dust wind from the outside by closing an air duct by a ventilating door when the air pressure outside the room increases and to stop the blower.
CONSTITUTION: A through hole having a grid 6 is provided at the wall 3 of a room 1, and an air duct 8 is formed at the inner side of the through hole 4. A blower 9 is provided at the room inner side end of the air duct 8, and a ventilating door 11 is provided at the downstream of the blower 9. The ventilating door 11 is opened by the blowing from the blower 9 to carry out the ventilation. When the blower 9 is stopped, the ventilating door 11 is suspended down by the dead weight but the air duct 8 is opened. When the outside air pressure is higher than the pressure within the room, the ventilating door 11 is closed by the air pressure, and, at the same time, a switch 10 is opened to stop the blower 9.
