Contamination separators are designed to retain solid particles carried by flowing water. They are used as a protection against desludging boiler fittings and water installations, with a much higher efficiency than in the case of oblique filters. The unique design forces slowed water flow, causing contaminations to deposit on the bottom of the separator. The neodymium magnetic stack captures paramagnetics and other magnetically active molecules. The stack is housed in a stainless steel cover that prevents contaminations from depositing directly on the magnets and also results in the possibility of removing them during the operation of an installation. The separators have non-mesh filters with a special weave that prevents them from clogging.
