Fluid baffle for a tank

A fluid baffle for use in a tank, the baffle comprising:

• a body at least partially formed by a first baffle piece comprising a first continuous wall coupled to a second baffle piece comprising a second continuous wall to define an interior volume and a plurality of fluid passage apertures at spaced positions around the body to allow fluid to easily pass into and out of the interior volume;
• wherein a shape of the body is such that outermost points of the body map onto points on a notional spherical volume and wherein recessed regions of the body between the outermost points are recessed from the outermost points, and
• wherein the recessed regions define saddle regions in between the outermost points, the first baffle piece including multiple ones of the saddle regions defined by the first continuous wall, and the second baffle piece including multiple ones of the saddle regions defined by the second continuous wall,
• wherein each of the first and second baffle pieces are formed such that the first and second continuous walls each define between about 60% to 90% of a surface area of the respective baffle piece, and the plurality of fluid passage apertures collectively establish all or almost all of the rest of the surface area.

A fluid baffle kit comprising:

• a first baffle piece and a second baffle piece which can be coupled together to form a fluid baffle body,
• wherein the first baffle piece comprises a first continuous wall and the second baffle piece comprises a second continuous wall,
• wherein, when the first and second baffle pieces are coupled together to form the fluid baffle body, the first and second continuous walls at least partially define an interior volume and a plurality of fluid passage apertures at spaced positions around the body to allow fluid to easily pass into and out of the interior volume;
• wherein the first continuous wall is integrally formed and uninterrupted, except by the fluid passage apertures, and defines a first flanged rim,
• wherein the second continuous wall is integrally formed and uninterrupted, except by the fluid passage apertures, and defines a second flanged rim, wherein the first flanged rim of the first baffle piece is configured to contact the second flanged rim of the second baffle piece when the first and second baffle pieces are coupled together,
• wherein, when the first and second baffle pieces are coupled together, a shape of the body is such that outermost points of the body map onto points on a notional spherical volume and wherein recessed regions of the body between the outermost points are recessed from the outermost points, and
• wherein the recessed regions define saddle regions in between the outermost faces.
