Abstract
An air pre-cleaner spin tube includes a vaned inlet section including an inlet flange, and an outer tube inlet portion including an outer wall forming a nozzle that defines a radial direction, and a longitudinal axis. Also, a central stem is disposed in the nozzle, and a plurality of vanes extends from the central stem to the outer wall.
Claims20
An air pre-cleaner spin tube comprising:
- a vaned inlet section including:
- an inlet flange;
- an outer tube inlet portion including an outer wall forming a nozzle defining a radial direction and a longitudinal axis;
- a central stem disposed in the nozzle;
- and
- a plurality of vanes extending from the central stem to the outer wall;
- a diffuser midsection;
- and
- an outlet section including:
- a portion of an outer wall,
- a cylindrical annular portion, and
- a tapered diffuser section that extends axially from an outlet flange toward the cylindrical annular portion,
- wherein the cylindrical annular portion extends axially from the tapered diffuser section to an area within a section, of the diffuser midsection, that defines a flare angle and extends to the portion of the outer wall, and
- wherein a taper axial height of the tapered diffuser section is less than a height of the cylindrical annular portion.

An air pre-cleaner spin tube comprising:
- a midsection including:
- a first diffuser section defining a first flare angle, and
- a second diffuser section extending from the first diffuser section and defining a second flare angle that is greater than the first flare angle;
- and
- an outlet section including:
- a portion of an outer wall,
- a cylindrical annular portion, and
- a tapered diffuser section that extends axially from an outlet flange toward the cylindrical annular portion,
- wherein the cylindrical annular portion extends axially from the tapered diffuser section to an area within the second diffuser section,
- wherein the second diffuser section extends to the portion of the outer wall, and
- wherein a taper axial height of the tapered diffuser section is less than a height of the cylindrical annular portion.
