Abstract

Filtration apparatus for filtering fluid passing through a conduit comprising: a fine filter comprising a first web extending across the conduit and having a plurality of relatively fine apertures; a support which acts as a coarse filter and also supports the fine filter, the support having a second web which extends transverse to the conduit axis, axially within the conduit and has a filtering surface inclined to the conduit axis, wherein the support has apertures being provided by bores within the filtering surface of the second web, the bores having, when viewed axially with respect to the conduit, a substantially circular cross section. Preferably the second web includes a plurality of bores whose axes extend substantially parallel to the conduit axis. Preferably the plurality of bores each has circular cross sections or elliptical cross sections.
