ABSTRACT:
A two-stage air cleaner with side-by-side elements. The cleaner has a first element (30), a second element (32) which itself may have a safety element (35). The first element (30) is preferably a conical inertial separator having a scavenge outlet (38). The second element preferably employs a pleated filter (50) which receives cleaned air (indicated by arrows 104) which passes through the filter (as indicated by arrows 106) to the outlet tube (56). In an alternative embodiment, pleated filter (50a) may have a reverse taper corresponding to that of the conical inertial precleaner (30a), thereby reducing the size of the housing.
