How to dose Fernox Express via a Fernox TF1 Filter
Fernox TF1 Total Filter Leaflet
TF1 Total and Compact Filter Range
The TF1 Total Filter is constructed from a high strength, glass reinforced polymer, which has good hydrolysis resistance as well as high resistance to strain and abrasion. The polymer is compatible with glycols and additives and is suitable for use in central heating systems.
The TF1 Total Filter has been designed to ensure there is minimal pressure loss whilst continuing to maintain a high collection efficiency. The unique hydrocyclonic action, magnet assembly, and area of low flow have all been engineered to allow the filter to capture a range of system contaminates, whilst not impacting the rest of the heating system.
The TF1 Total Filter utilises a range of high-quality component parts that ensure the filter offers optimum performance. All isolation valves are designed to allow users to operate them easily by hand, whilst also providing a secure connection to the system and a robust service point. The magnet is manufactured using a premium grade of neodymium, enabling a high-efficiency capture rate, as well as a robust filtration medium that will ensure a continued and consistent level of collection.

Operating Principle – Contaminated water enters the filter via the manifold, carrying a variety of system debris and particulate matter held in suspension. This debris, including ferrous impurities such as Magnetite, move through the manifold and into the main body of the filter.
The TF1 Total Filter utilises Hydrocyclonic filtration. A Hydrocyclone is a static device that applies centrifugal force to a liquid mixture to promote the separation of particles.
The Hydrocyclonic action has been designed to convert incoming liquid velocity into rotary motion. As water enters the filter, it spins around and down the outside of the filter, carrying particles with it. The shape of the filter has been designed to create a dead zone at the bottom where heavier particles are deposited.
The Hydrocyclone in the TF1 Total Filter has been optimised in order to allow for the maximum filtration ability of both magnetic and non-magnetic material.
Once the flow of water has reached the bottom of the filter, water moves back up through the centre of the TF1 Total Filter, carrying particles over the magnet sheath, promoting further magnetic filtration and enhancing the collection capabilities of the filter.
Any dirt collected within the filter can then be discharged by removing the magnet from the sheath and opening the drain valve. This procedure is shown in the cleaning guide and does not require system shutdown, or the filter to be disassembled.
