Vent assembly

1. A vent assembly comprising a housing, a flow conduit and a weather hood, the flow conduit having a proximal end for being fluidly connected to a source of material and an open distal end, the housing having a base portion, a side wall portion, and a top portion, the flow conduit comprising a baffle located between the base portion and the top portion of the housing to direct fluid flowing from the flow conduit towards the weather hood and through the housing in a direction towards the top portion of the housing, wherein the weather hood has a transverse dimension greater than a transverse dimension of a distal edge of the baffle, wherein the baffle extends beyond the distal end of the flow conduit.

2. The vent assembly according to claim 1 , wherein the baffle directs the fluid flowing from the flow conduit in a vertical direction and towards the top portion of the housing, optionally towards a periphery of the top portion of the housing.

3. The vent assembly according to claim 1 , wherein the baffle extends endlessly around a periphery of the flow conduit.

4. The vent assembly according to claim 1 , wherein the flow conduit comprises a flange located at or adjacent the distal end and the baffle is secured to the flange.

5. The vent assembly according to claim 1 , wherein the flow conduit comprises a tubular portion of constant cross section and the baffle extends outwardly around the tubular portion.

6. The vent assembly according to claim 1 , wherein an internal angle defined between the flow conduit and the baffle is acute.

7. The vent assembly according to claim 1 , wherein the baffle is provided with or comprises one or more baffle drainage ports.

8. The vent assembly according to claim 1 , wherein the base portion of the housing comprises one or more drainage ports.

9. The vent assembly according to claim 1 , wherein the weather hood has a flow conduit-facing face and an environment-facing face, and the weather hood further comprises a drainage channel or tube in communication with the environment facing face.

10. The vent assembly according to claim 1 , wherein the weather hood is attached to the side wall portion of the housing, optionally connected by a perforate member and/or support bars.

11. The vent assembly according to claim 1 , further comprising a flame arrester assembly.

12. The vent assembly according to claim 1 , further comprising one or more of a pressure relief valve, a vacuum relief valve, a combined pressure relief/vacuum relief valve.

13. A vent assembly comprising a housing, a flow conduit and a weather hood, the flow conduit having a proximal end for being fluidly connected to a source of material and an open distal end, the housing having a base portion, a side wall portion, and a top portion, the flow conduit comprising a baffle located between the base portion and the top portion of the housing to direct fluid flowing from the flow conduit towards the weather hood and through the housing in a direction towards the top portion of the housing, wherein the weather hood has a transverse dimension greater than a transverse dimension of a distal edge of the baffle, wherein an open top of the housing is covered, at least in part by a gauze or mesh or plate comprises perforations or apertures.

14. A vent assembly comprising a housing, a flow conduit and a weather hood, the flow conduit having a proximal end for being fluidly connected to a source of material and an open distal end, the housing having a base portion, a side wall portion, and a top portion, the flow conduit comprising a baffle located between the base portion and the top portion of the housing to direct fluid flowing from the flow conduit towards the weather hood and through the housing in a direction towards the top portion of the housing, wherein the weather hood has a transverse dimension greater than a transverse dimension of a distal edge of the baffle, wherein the weather hood has a depending wall formed at or towards its periphery and the depending wall is provided with a secondary baffle, which is outwardly directed.

15. The vent assembly according to claim 14 , wherein the secondary baffle extends outwardly around the entire depending wall.

16. The vent assembly according to claim 15 , wherein an internal angle defined between the depending wall and the secondary baffle is acute.

17. The vent assembly according to claim 14 , wherein the secondary baffle comprises one or more drainage apertures or drainage tubes or channels.
