ABSTRACT:
An improved cylindrical two-stage air cleaner in which the overall efficiency of the cleaner is improved by changing the configuration of filtering means therein from a cylindrical one to a conical one, and in which improved structure is included for sealing the cleaner to prevent passage of incoming air to the outlet without being cleaned, and to automatically scrape particulate matter from the inside of the cleaner housing each time a principal filter is changed.
