Abstract

True point of use filters are necessary in certain manufacturing operations where it is desirable to provide, at the outlet and at the point of use, maximum filtration of such fluids as water, gases or even solvents. Most of the presently marketed filters require a special holder to be built into the line requiring cutting, welding or other modifications which are costly and time consuming.

True point of use filters are necessary in certain manufacturing operations where it is desirable to provide, at the outlet and at the point of use, maximum filtration of such fluids as water, gases or even solvents. Most of the presently marketed filters require a special holder to be built into the line requiring cutting, welding or other modifications which are costly and time consuming.

As illustrated, a rubber stopper comprises a pair of opposed frustocones 10 and 11, a radially extending flange portion 12 and a plurality of passageways 13 extending therethrough. A plurality of porous ceramic filter rods 14 project into the passageways 13, the filter rods having fused therein at one end thereof glass beads 15 to seal the ends so that all fluid must pass through their porous sidewalls. The flange 12 serves as a seal for the adapter, and may easily be positioned in a conventional coupling having a threaded nut 16 which threads onto a pipe 17, coupling the pipe 17 to an outlet pipe 18. In this manner, conventional couplings may be utilized instead of large bulky and expensive holding fixtures.
