Claim Text:
1. An air or gas cleaning apparatus comprising: an inlet providing an intake for particulate-pervaded air or gas; an external housing comprising walls extending conically at a first angle from a proximal end of a first diameter to a distal end of a second diameter greater than the first diameter, wherein the external housing proximal end is coupled to the inlet, and wherein the external housing distal end comprises an aperture and at least one channel extending along the interior of the external housing; an inner conical surface comprising a distal end of the second diameter coupled to the external housing distal end and walls extending at a second angle less than or equal to the first angle from the distal end less than midway within the interior of the external housing to a proximal end, wherein the inner conical surface proximal end comprises an impeller mount and an aperture aligned over the external housing distal end aperture providing a clean air or gas outlet; a collapsible volume towards the distal end of the external housing interior, wherein the collapsible volume is a narrowing volume formed based on a difference of the first angle and the second angle at which the inner conical surface walls extend from the external housing distal end relative to the external housing walls; a powered impeller coupled to the inner conical surface impeller mount and disposed within the external housing, wherein the powered impeller comprises a motor powering rotation of the powered impeller about an axis, wherein said rotation induces suction of the particulate-pervaded air or gas through the inlet, accelerates the particulate-pervaded air or gas within the external housing, and creates forces within the external housing, said forces comprising a centrifugal force separating particulates from the particulate-pervaded air or gas by moving the particulate-pervaded air or gas radially outward to the collapsing volume in between the external housing walls and the inner conical surface walls with the channel providing a baffle trapping and isolating the particulates from cleaned air or gas and with the cleaned air or gas pushed through to the clean air or gas outlet; and a particulate outlet providing an aperture along the external housing walls at an end of said collapsing volume, wherein said forces and air or gas flow resulting from said forces further move the particulates through the collapsing volume and out the particular outlet aperture.
