According to the present invention, a ventilating system is used to equalize a first pressure within an enclosure, and a second pressure outside of the enclosure. The ventilating system includes a body member having an exterior surface adapted to seal against an inner surface of the enclosure. The body member has an interior surface forming a conical section oriented in a first direction. The ventilating system also includes an overpressure relief member for venting fluids from within the enclosure when the first pressure is greater than the second pressure. The overpressure relief member has an outside surface that forms a conical section oriented in the first direction. The overpressure relief member includes an outside surface that separates from the interior surface of the body member when the first pressure is greater than the second pressure. The outside surface of the overpressure relief member is designed to seal more tightly against the interior surface of the body member when the first pressure is less than the second pressure. The overpressure relief member also has an interior surface that forms a conical section oriented in a second direction. The ventilating system includes an underpressure relief member for receiving fluids into the enclosure when the first pressure is less than the second pressure. The underpressure relief member has an outside surface that forms a conical section oriented in the second direction. The outside surface of the underpressure relief member separates from the interior surface of the overpressure relief member when the first pressure is less than the second pressure. Moreover, the outside surface of the underpressure relief member is designed to seal more tightly against the interior surface of the overpressure relief member when the first pressure is greater than the second pressure.
