Abstract
An air precleaner for mechanically removing particulate contaminants from an enclosed environment includes a peripheral air intake manifold that is in communication with the inlet port of a mechanical separation unit, and a central exhaust port that is in communication with the air output port of the mechanical separation unit. The precleaner can be inserted into or onto a vacuum system from which airborne particulate matter is to be removed. The precleaner includes a container which may be a two part container formed of a fitting assembly and a canister for the collection of particulates. The canister itself may be divided into a top and a bottom, compartment by a flange extending outwardly around the outer edge of the mechanical separation unit. Particulate matter collects in the bottom compartment of the canister, which can be periodically removed from the rest of the precleaner to dispose of the accumulated particulates.
