<p>Integral coalescer filter-membrane device (10) provides clean sample gas to gas analyzers and includes a housing (34), an inlet port (24) for feed gas, an outlet port (14) to withdraw clean sample gas essentially free of entrained liquids, such as water, and particulate material which might contaminate or interfere with the gas analyzer, a bypass port (30), and a drain port (36) to remove by gravity coalesced liquid. Device (10) includes a filter tube (38) with a coalescer layer (40) to coalesce and filter the feed gas stream and a chamber (16) having a supported hydrophobic selected porosity membrane (18). Outlet port (14) receives clean sample gas from the upper portions of chamber (16), while bypass port (30) removes coalesced, filtered gas.</p> |
