What is the difference between resin trap and precision filter? Resin trap: a device used to trap resin particles that come out of the ion exchanger with the water.When using resin for online water treatment,When the quality of the resin is poor (the strength is not enough), the water pressure disturbance is large (especially the high pressure disturbance), and the wall of the resin is damaged,The resin goes into the whole water system,Affect the normal operation of other equipment of the system,Therefore, resin traps need to be installed.The resin trap is mainly to install a filter with a much smaller aperture than the resin on the water system pipe near the outlet of the resin-containing equipment such as ion exchanger,And has the function of Flushing.When the resin passes,Can be intercepted by the filter,At the same time,Automatic flushing by differential pressure before and after,Drain the captured resin out of the system.Precision filter (also known as security filter ),The shell of the cylin
