ABSTRACT:
Apparatus and method for supplying clean air to a closed vehicle from an ambient source of air polluted with particulate matter. This is accomplished by drawing in air as a hollow cylindrical flow, converting it to the form of a flat sheet of air having components of motion radial and tangential with respect to an axis, deflecting the air by more than 90.degree. to convert it to a conical whirling flow tapering toward the axis while retaining the tangential component of motion, purging from the flow particulate matter discharged centrifugally at the site of the deflection, skimming the conical flow to remove successive outer portions thereof together with the particulate matter centrifugally displaced thereinto, again deflecting the flow by more than 90.degree., in the opposite sense, to convert it to a flat whirling flow retaining the tangential components of motion and having a radially outward component of motion, converting the tangential component to pressure head, and discharging the flow radially as a sheet of air free from particulate polution.
