Abstract
A vent that includes: a rotary head with blades arranged between a top and bottom section of the rotary head; a fixed component to mount the rotary head to a roof of a building, the fixed component having a throat that provides a flow path from inside the building to an interior of the rotary head; and a diffuser to split airflow vented from the throat and direct the vented airflow out through the rotary head.
Claims21
A vent that includes:
- a rotary head with blades arranged between a top and bottom section of the rotary head;
- a roof base component to mount the rotary head to a roof of a building, the roof base component having a throat that provides a flow path from inside the building to an interior of the rotary head;
- and a diffuser, wherein the diffuser separates air flow vented through the throat into separate airstreams so that the airflow is vertically distributed over the height of the blades when exiting the rotary head.
A vent with a rotary head with blades arranged between a top and bottom section of the rotary head, and a roof base component to mount the rotary head to a roof of a building, the roof base component having a throat that provides a flow path from inside the building to an interior of the rotary head, wherein an outer periphery of the top section forms an angle relative to an exit of the throat in the order of 25 degrees so that the roof base component and rotary head are able to operate on an angle to match a roof pitch in the order of up to 15 degrees from horizontal.
A vent with a rotary head with blades arranged between a top and bottom section of the rotary head, and a roof base component to mount the rotary head to a roof of a building, the roof base component having a throat that provides a flow path from inside the building to an interior of the rotary head, wherein the roof base component includes a brace that extends across the throat to carry a support on which the rotary head is mounted and the brace, throat and roof base component are integrally formed.
A vent with a rotary head with blades arranged between a top and bottom section of the rotary head, and a roof base component to mount the rotary head to a roof of a building, the roof base component having a throat that provides a flow path from inside the building to an interior of the rotary head, wherein the profile of the blades is such that a substantially constant distance gap is provided between overlapped regions of adjacent blades.
A vent with a rotary head with blades arranged between a top and bottom section of the rotary head, and a roof base component to mount the rotary head to a roof of a building, the roof base component having a throat that provides a flow path from inside the building to an interior of the rotary head, wherein the blades are canted inwardly from the bottom section and present a straight line profile between the top and bottom sections.
