A system and method for extracting essential oils from organic material is provided. One embodiment places organic material into an extraction chamber that is a cylindrical wall of rigid material, wherein a diameter and a height of the extraction chamber is sized to define an interior that accommodates a desired amount of an organic material having essential oils; fills the extraction chamber with a solvent after the organic matter has been placed into the extraction chamber; and moves a vortex plunger disposed over the surface of the organic material in a repeated upward and downward motion during an agitation process so that the vortex vanes generate a fluid vortex in the solvent, wherein the fluid vortex causes the solvent to be drawn upward into the organic material and then to be pushed downward through the organic material so that the solvent extracts essential oils from the organic material.

A separator apparatus is described for separating liquids and solids from a gas. The separator apparatus includes a reverse flow cyclone comprising a cylindrical section, a conical section, and a top, the cylindrical section having a feed inlet, the top having a gas outlet, and the conical section having a reject outlet at the bottom thereof. An axial cyclone is disposed in the cylindrical section, the axial cyclone oriented with a first end located proximate to the top of the apparatus and a second end opposite the first end, the axial cyclone having a tapered entrance fixture at the second end thereof and having a wall with a plurality of openings located between the first end of the axial cyclone and a midpoint of the axial cyclone. A drain plate is coupled to the cylindrical section below the openings of the axial cyclone.

A surface cleaning apparatus comprises an air treatment chamber with a moveable member positioned therein. An end wall of the air treatment chamber is openable in response to a moveable member being longitudinally translated through at least the portion of the air treatment chamber. The driving assembly includes a handle and a drive rod that is rotatably mounted about a longitudinally extending axis of the drive rod between a stored position in which the moveable member is in a stored position and an operable position in which the moveable member is translatable through at least a portion of the chamber. In the stored position, the handle is longitudinally spaced from the first and second ends of the air treatment chamber and, when the driving assembly is in the operable position, the driving assembly is operable to longitudinally translate the moveable member through at least a portion of the chamber.
