摘要： A filtration device for removing particulate matter from liquids has a rigid tubular body that terminates in a pair of open ends. The body has a plurality of openings therein, leading to a bore, and a layer of a filtration material, such as a polypropylene mesh, is stretched over the surface of the body. The filtration material has a preferred pore size of between 30 and 60 microns. The body is manufactured from plastic, and has a support means which prevents collapse of the filtration device under pressure. The filtration material is attached near the ends of the body, and a pair of end caps are attached to the ends. The end caps serve as means of fitting the filtration device within equipment such as automated photographic processing apparatus. The materials used to manufacture the filtration device are chosen so as to be resistant to both the physical conditions (such as temperature, pressure and flow rate) and the chemical conditions of the apparatus. An advantage of having the filter material on the outside is that liquid flows from outside the filter, through the body and the inside, trapping particulate matter on the outside surface of the filter. The filter can be removed from the equipment where it is used, and particulate matter trapped on its surface washed off, and the filter can be reused, resulting in a substantial cost savings compared to the use of disposable filters.

摘要： A filtration device and a method of manufacturing the same, the filter device including a tubular body having a body wall defining a rigid support structure with a plurality of inlet openings, the body wall further having an inside wall structure and an outside wall structure, a central bore extending through the tubular body and being coextensive with the body wall, and an end portion on each opposing end of the body wall. The filtration device further includes a filtering medium disposed between the inside wall structure and the outside wall structure of the body wall, thereby filling the plurality of inlet openings.
