ABSTRACT:
An air cleaner and deflecting intake tube therefor. An air cleaner having a two-part housing (14,16) as a primary filter (54) and a secondary safety filter (52). Primary filter has a neck (66) which is compressed by clamp (86) upon sleeve (80) of the secondary filter. When the secondary filter is affixed to a machine it provides a filtering function whether or not the remainder of the filtering apparatus is present. Likewise, the primary filter functions properly without the housing present.
An intake tube (20) having a deflecting surface (122) causes an air flow (150) to have an axial and downward trajectory which, when used in combination with a cylindrical housing, produces a helical air flow resulting in centrifugal separation of heavy particulate matter. The primary filter (54) is preferably disposable.
