The first valve is attached the first valve mount, and the second valve is attached to the second valve mount. A bracket may also be included. The bracket includes a body and support arms extending from the body. The support arms are attached to an inner surface of the housing. The support arms are configured to attach the housing to an enclosure surface. The first valve is a unidirectional valve, while the second valve may be an equalization valve or a unidirectional valve. ## Claims ### Claim 1 A vent assembly, comprising: a housing comprising: a first valve mount defining a first valve opening and a first flow opening surrounding the first valve opening, and a second valve mount defining a second valve opening;

a second flow opening that is larger than the first flow opening of the first valve mount; and a second valve passage that is larger than the second valve opening of the second valve mount. ### Claim 3 (depends on 1) The vent assembly of claim 1, further comprising adhesive disposed on a second surface of the housing, the adhesive configured to attach and seal the housing to the enclosure surface. ### Claim 4 (depends on 1) The vent assembly of claim 1, wherein the support arms are configured to provide a predetermined clamping force. ### Claim 5 (depends on 4) The vent assembly of claim 4, further comprising adhesive disposed on the second surface of the housing, the adhesive configured to attach and seal the housing to the enclosure surface. ### Claim 6 (depends on 1) The vent assembly of claim 1 further comprising a protective cover attached to the first surface of the housing above the valve disc. ### Claim 7 (depends on 6) The vent assembly of claim 6, wherein, when the unidirectional valve is disposed in the open position, the protective cover does not prevent airflow through the first flow opening. ### Claim 8 (depends on 7) The vent assembly of claim 7, wherein the first flow opening includes a plurality of flow opening segments. ### Claim 9 A vent assembly, comprising: a housing comprising: a first valve mount defining a first valve opening and a first flow opening surrounding the first valve opening, and a second valve mount defining a second valve opening and a second flow opening surrounding the second valve opening; a first unidirectional valve attached to the first valve mount; a second unidirectional valve attached to the second valve mount; and a bracket comprising: a body, and support arms extending from the body and attached to a second surface of the housing, wherein the support arms are configured to align the housing to an enclosure surface. ### Claim 10 (depends on 9) The vent assembly of claim 9, wherein the body of the bracket defines: a first valve passage that is larger than the first valve opening of the first valve mount; a first flow opening that is larger than the first flow opening of the first valve mount; and a second valve passage that is larger than the second valve opening of the second valve mount; and a second flow opening that is larger than a second flow opening of the second valve mount. ### Claim 11 (depends on 9) The vent assembly of claim 9, further comprising adhesive disposed on a second surface of the housing, the adhesive configured to attach and seal the housing to the enclosure surface. ### Claim 12 (depends on 9) The vent assembly of claim 9, wherein: each unidirectional valve includes a valve disc and a valve stem extending from the valve disc, the valve stem including an end portion; the valve stem for the first unidirectional valve is disposed within the first valve opening; the valve stem for the second unidirectional valve is disposed within the second valve opening; the end portion of the first unidirectional valve engages the first valve mount; and the end portion of the second unidirectional valve engages the second valve mount. ### Claim 13 (depends on 12) The vent assembly of claim 12, wherein: when the first unidirectional valve is disposed in a closed position, the valve disc is configured to form a seal with a first surface of the housing to prevent airflow through the first flow opening; when the first unidirectional valve is disposed in an open position, the valve disc is configured to extend above the first surface of the housing to allow airflow through the first flow opening; when the second unidirectional valve is disposed in the closed position, the valve disc is configured to form a seal with the first surface of the housing to prevent airflow through the second flow opening; and when the second unidirectional valve is disposed in the open position, the valve disc is configured to extend above the first surface of the housing to allow airflow through the second flow opening. ### Claim 14 (depends on 13) The vent assembly of claim 13, wherein the first flow opening includes a plurality of first flow opening segments, and the second flow opening includes a plurality of second flow opening segments. ### Claim 15 (depends on 9) The vent assembly of claim 9, further comprising: a protective cover attached to a first surface of the housing above the first and second unidirectional valves, wherein, when the first unidirectional valve is disposed in an open position, the protective cover does not prevent airflow through the first flow opening, and wherein, when the second unidirectional valve is disposed in an open position, the protective cover does not prevent airflow through the second flow opening. ### Claim 16 (depends on 15) The vent assembly of claim 15, wherein the support arms are configured to provide a predetermined clamping force. ### Claim 17 (depends on 16) The vent assembly of claim 16, further comprising adhesive disposed on the second surface of the housing, the adhesive configured to attach and seal the housing to the enclosure surface. ### Claim 18 A method, comprising: providing a vent assembly for a sealed enclosure, the vent assembly including: a housing comprising: a first valve mount defining a first valve opening and a first flow opening surrounding the first valve opening, a second valve mount defining at least a second valve opening; a first valve attached to the first valve mount; a second valve attached to the second valve mount; and a bracket comprising: a body, and support arms extending from the body and attached to a second surface of the housing, wherein: the support arms are configured to align the housing to an enclosure surface, the first valve is a unidirectional valve, the second valve is an equalization valve or a unidirectional valve, and the support arms are configured to align the housing to an enclosure surface. ### Claim 19 (depends on 18) The method of claim 18, wherein the second valve is the equalization valve. ### Claim 20 (depends on 18) The method of claim 18, wherein;
