Resin Traps / Strainer
Construction：
The wedge wire element in a Resin Trap/ Strainer is normally a slot tube, but can also be a cylinder. A Resin Trap / Strainer is normally closed on one side and has a flange on the other. They can be made for flow-in-to-out (FITO) or flow-out-to-in (FOTI) filtration.
Principle：
A Resin Trap / Strainer normally serves to retain particles in a process flow. The quantity of particles is normally very low, so that cleaning can be done during flow interruption.
Application：
A resin trap is normally used:
to capture expensive resin that escapes from a treatment vessel by accident
to protect equipment further downstream
A strainer is often used in tubes to block unwanted particles or dirt that would otherwise damage downstream equipment. Cleaning is carried out by removing the strainer from the tube.
Advantages:
very precise slots for perfect particle retention combined with minimum obstruction of the process flow.
flexibility in design.
strong construction (self supporting).
large open area.
plug-resistant slot design.
