<p>The combination apparatus (20) silences and filters air flow and separates air-contaminant mixtures. An air filter (100) joins an annular housing (22) which has an outer wall (24) and a channel (26) defining a central axis (28), the channel (26) having a primary gas inlet (30) coupled to the air filter (100) and a primary gas outlet (32) and a channel wall (34). The apparatus (20) has a secondary inlet port (42) passing through the outer wall (24). A secondary outlet port (46) 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 (90) is contained within the channel (26). A passageway between the secondary inlet and the secondary outlet is defined exteriorly by the outer wall (24) and interiorly by the channel wall (34).</p> |
