ABSTRACT:
An air cleaning device for use in connection with clean air usage such as with internal combustion engines or to provide cleaned air for ventilation purposes, the air cleaner device comprising a directional hood having a substantially unrestricted air intake and a short throat directional separation chamber into which incoming air is drawn and in which incoming contaminants and moisture are centrifuged by a multiplicity of directional vanes onto and along an adjacent baffle member leading to an annular discharge chamber through which a driven spinner assembly ejects contaminants and moisture through rearward facing ports and creating a relatively low to high pressure gradient into and through the discharge chamber with the pressure gradient increasing to accelerate the movement of the contaminants and moisture through the discharge chamber and through the discharge ports with the pressure of ejection being greater than the external ambient air pressure.
