<p>This invention is a method, and apparatus for an aerosol chamber (300) having an input opening (343), with back pressure created in the chamber by an aperture barrier (360), such as a disk having a plurality of concentric, and circumferential disposed sets of openings (361) to reduce the size of particles applied at the input opening before leaving the output opening (320); which is of lesser diameter than the input opening, which extends to the input opening by an arcuate surface of revolution that serves to redirect interiorly of the chamber aerosol particles that have entered the chamber, and reached the surface of revolution.</p> |
