It removes and traps sludge, rust, scale, and other debris from the circulating water before these particles can damage key components such as the boiler heat exchanger, pump, and radiator cores.\u003c\/p\u003e\n\u003ch3 data-start=\"370\" data-end=\"394\"\u003eFunction \u0026amp; Purpose\u003c\/h3\u003e\n\u003cp data-start=\"395\" data-end=\"994\"\u003eInstalled in the \u003cstrong data-start=\"412\" data-end=\"430\"\u003e28 mm pipework\u003c\/strong\u003e of a central heating system—typically on the flow or return near the boiler or pump—the TF1 filter uses both magnetic and non-magnetic filtration. Powerful internal magnets attract and hold ferrous particles (like rust), while internal baffling traps non-magnetic debris. By capturing contaminants circulating in the system water, the filter helps prevent blockages, improves heat transfer, reduces noise, and enhances overall system efficiency. Periodic draining or back-flushing of the filter removes the collected debris and keeps the system operating cleanly.\u003c\/p\u003e\n\u003ch3 data-start=\"996\" data-end=\"1015\"\u003eCompatibility\u003c\/h3\u003e\n\u003cp data-start=\"1016\" data-end=\"1379\"\u003eThis filter is sized for \u003cstrong data-start=\"1041\" data-end=\"1075\"\u003e28 mm central heating pipework\u003c\/strong\u003e, making it suitable for larger domestic systems or light commercial systems that use that pipe diameter. It is compatible with most combi, system, and conventional boilers that accept inline filtration and works alongside other system protection products such as corrosion inhibitors and scale reducers.\u003c\/p\u003e\n\u003ch3 data-start=\"1381\" data-end=\"1409\"\u003eDesign \u0026amp; Build Quality\u003c\/h3\u003e\n\u003cp data-start=\"1410\" data-end=\"1787\"\u003eFERNOX engineers the TF1 Total Filter with a robust body and powerful internal magnets for long-term, reliable performance. The plastic housing resists corrosion and withstands the typical pressures and temperatures found in heating systems. Servicing points and drain valves are designed for ease of use so that captured debris can be removed without disconnecting the filter.\u003c\/p\u003e\n\u003ch3 data-start=\"1789\" data-end=\"1807\"\u003eKey Benefits\u003c\/h3\u003e\n\u003cp data-start=\"1808\" data-end=\"2200\"\u003eInstalling the TF1 filter helps extend the life of boiler and heating components by reducing the amount of circulating debris that causes wear, noise, and blockages. Cleaner system water improves circulation, eliminates cold spots on radiators, and supports more efficient heat transfer. Regular maintenance of the filter contributes to reduced servicing costs and fewer breakdowns over time.\u003c\/p\u003e\n\u003ch3 data-start=\"2202\" data-end=\"2226\"\u003eIdeal Applications\u003c\/h3\u003e\n\u003cp data-start=\"2227\" data-end=\"2681\"\u003eThe \u003cstrong data-start=\"2231\" data-end=\"2264\"\u003eFERNOX TF1 Total Filter 28 mm\u003c\/strong\u003e is ideal for central heating systems with \u003cstrong data-start=\"2307\" data-end=\"2325\"\u003e28 mm pipework\u003c\/strong\u003e, including larger domestic and light commercial installations. It’s particularly beneficial when installed as part of a system protection regime during new build projects, boiler upgrades, or as preventative maintenance where signs of sludge or debris build-up are present.
