Abstract

An in line fluid filter has an elongate tubular housing with end fittings. An axially disposed closed elongate cylinder is held within the housing defining an annular fluid chamber therebetween. The annular fluid chamber is divided into a plurality of concentric, parallel annular flow paths by at least one elongate concentric, fluid impermeable partition. The flow paths are occupied by a woven wire filter fabric with coarse mesh. This provides a long tortuous filter path that does not readily clog up and that prevents the passage of large particles.
