Magnetic filters that capture iron oxide and debris in hydronic heating systems. The collection includes the Fernox TF-1 magnetic and non-magnetic debris filter with 1" fittings, Fernox Protector+ filter fluid in a 13 oz express can and the Navien NaviClean magnetic filter.
Install a magnetic filter on the return line before the boiler to protect heat exchangers, pumps and valves, especially on high efficiency boilers. Match the connection size to the return piping and leave room for service. Clean the filter at each maintenance visit, and consider an inhibitor fluid to limit corrosion.
