AIR FILTER SURROUNDING SEPARATOR
First Claim
1. An air filter for removing particulate matter and other impurites from an airstream comprising a casing, said casing have an upper part and a lower part, said upper part and said lower part being connected together at an airtight joint by clamping means, said upper part of said casing being provided with an inlet passage which forms a spiral path for said uncleansed inlet air and is in communication with an inlet ducting, said inlet ducting being tangentially directed adapted to impart a preswirling motion to said inlet air passing therethrough, said inlet ducting being connected in communication with the cylindrical portion of a cyclone separator, said air entering said cyclone separator as a swirling mass, said air moving from said cylindrical portion of said cyclone separator toward the conical section of said separator and then back toward said cylindrical portion of said separator, the relatively heavier particles entrained within said air being removed by said separator and collected by a collecting means operatively connected to said separator, said cyclone separator being provided with air outlet ducting at its cylindrical portion in communication with the outside surface of a filter adapted to direct the partially cleansed air from said separator to the outside surface of the filter media of a filter, said filter enclosed within said casing and surrounding said cyclone separator, said filter media removing substantially all of the remaining particulate matter and impurities from said airstream, a third air guide means in communication with the inside surface of the filter media of the filter for effectively directing the now cleansed air out of said air filter.

Abstract
An air filter for removing particulate matter from an airstream comprising a casing with a first air guide means for efficiently directing the uncleansed particulate-laden air into an inertial separating means enclosed within said casing, said inertial separating means adapted to remove relatively heavy particles from the airstream; a second air guide means for efficiently directing the airstream from said inertial separation means to the outer surface of the filter media of a filter enclosed within said casing and surrounding said inertial separating means, said filter media removing substantially all of the remaining particulate matter from said airstream; and a third air guide means for efficiently directing the now cleansed airstream out of said air filter.
