A filter, which may be used to filter particles of resin as well as protect against sudden loss of resin from an effluent discharged from an ion-exchange column, a first plate mounted between a flanged end of a first branch and a flanged end of a pipe, a second plate mounted between a blind flange and a flanged end of a second branch, and a perforated tube fitted through said branches so as to leave an annular space around the perforated tube. A first end of the perforated tube is threaded into a threaded aperture in the first plate to provide for manufacturing tolerances. A second end of the perforated tube is received by an annular groove on one face of the second plate to provide for a particle-tight seal, and the annular groove circumscribes a larger aperture in the second plate. A flanged end of a third branch is mounted to a flanged end of another pipe. A transparent sight may be provided at a fourth branch.
