ABSTRACT:
The combination apparatus silences and filters air flow and separates air-contaminant mixtures. An air filter joins an annular housing which has an outer wall and a channel defining a central axis, the channel having a primary gas inlet coupled to the air filter and a primary gas outlet and a channel wall. The apparatus has a secondary inlet port passing through the outer wall. A secondary outlet port defines an opening in the channel wall such that there is no straight line flow path between the secondary inlet and the secondary outlet. An air silencer is contained within the channel. A passageway between the secondary inlet and the secondary outlet is defined exteriorly by the outer wall and interiorly by the channel wall.
