A filtration apparatus for separating particulate and liquid impurities, such as dust, liquid or oil, from a natural gas. The filtration apparatus has a horizontally oriented filter enclosure with a plurality of filter elements which are not in parallel with the long axis of the enclosure, thus enabling filtered particles to fall out of the filter elements into a collection sump for later removal. A dividing plate, upon which the filter elements are mounted, is angled slightly out of level for the purpose of guiding the filtered particulate and liquid impurities to a collection sump. The gas flowing into the enclosure undergoes a rapid expansion, which serves to remove larger particles and liquids entrained in the gas. The gas is further "pre-filtered" by forcing it through a tortuous path of abrupt changes in direction prior to encountering the filter elements.
