Designed for use with Fernox TF1 in-line system filters or other similar filters, this unique inhibitor package includes an active dispersant which is proven to aid the safe collection of corrosion, debris and scale via a filter. The Protector + Filter Fluid Express enhances the performance of a system filter whilst offering full protection against corrosion and scale formation. This innovative, proven formulation also extends system life and maintains optimum efficiency, while still being an environmentally friendly formulation. Concentration levels should be checked as part of the annual maintenance system service. The Fernox Express range uses Barrier Pressure Pack technology and compressed air propellent to expel the product so the entire range is non-flammable. The propellent (compressed air) is not mixed with the active product so there is no risk of air ingress into the system which could accelerate future risk of corrosion.
One single dose of this product treats and protects a larger sized property with a heating system of 130 litres, up to 16 radiators, or 250 sqm of underfloor heating. Fernox Protector+ Filter Fluid Express can be dispensed directly into a radiator air vent, system filling loop, or via a TF1 Filter using the appropriate adapter supplied with the product. Fernox Express takes less then 30 seconds to dose the system without the need to drain down the system, saving time on-site. If dosing via a TF1 Filter, the filter should be empytied of any collected contaminants prior to treating with Protector+ Filter Fluid. It takes less than 2 minutes to clean in situ. Simply Isolate the filter, remove the magnet from the sheath, open the drain valve and dispose of the contaminants before replacing the magnet and closing the drain valve. Fernox Protector+ Filter Fluid Express should remain in the system. It is not suitable for use in microbore systems. In single feed indirect cylinder, e.g. Primatic systems or similar, potable water chemicals must be used. For heavily sludged systems or new installations, Fernox recommends cleaning and flushing using Fernox Cleaner F3 or Power Cleaner F8 before treating with inhibitor. Protector+ Filter Fluid must be used in combination with an inline system filter. The installation of a system, or new boiler should comply with all local legislation and regulations.
Fernox Protector+ Filter Fluid Express is supplied in 400 ml pressurised cans.
Fernox Protector+ Filter Fluid Express is classified as non-hazardous for human health, but as with all chemicals keep out of reach of children. In case of contact with eyes or skin, rinse immediately with plenty of water.
Fernox Protector+ Filter Fluid Express is a blend of corrosion and scale inhibitors and dispersants:

Minerals in chalk or limestone rock collect as water permeates through the ground and collects in aquifers. These minerals remain within the water and are carried into the domestic water supply.
What causes limescale deposition?
They inevitably reach central heating and water systems, where they build-up over time to cause blockages in pipework, efficiency losses and the premature failure of components. These problems can arise in both the primary water system (the central heating system) and secondary (household hot water) system.
The mineral deposits, collectively known as limescale, consist primarily of calcium and magnesium carbonates which are generally insoluble. Limescale occurs when these deposits are formed as a result of heating water that contains soluble bicarbonate salts (which are thermally unstable and break down to form carbonates).
There are several factors that contribute to the build-up of limescale, including:
What should be done?
Prevention is always better than cure. In central heating systems, the addition of any Fernox Protector F1 will prevent deposition of limescale.
For domestic hot water systems, Fernox offers a range of scale reducers designed to provide either whole house or single appliance protection.
For whole house protection, the Fernox Electrolytic Scale Reducer should be installed on to the mains water supply to the property. To protect single appliances such as the boiler, the Fernox Magnetic Scale Reducer is ideal.
If the central heating system is already contaminated with limescale it should be cleaned using an acid-based cleaner such as Fernox DS40 Descaler & Cleaner. However, descaling alone will not restore the central heating system to its original condition. After descaling it is imperative to protect the system against further scaling by adding any Fernox Protector F1 or if a system filter is fitted Fernox Protector + Filter Fluid
If limescale formation has occurred within the hot water system, individual appliances such as kettles, showerheads and heat exchangers can be descaled using Fernox DS-3 Limescale Remover. For open vented systems Fernox Superconcentrate Limescale Preventer is an ideal way to keep system water scale-free.
Follow these steps to successfully dose your central heating system.
Make sure the system is turned off and allow radiators to cool down (1). Select a radiator and shut both the wheel-head and lock shield valves (2). If a thermostatic radiator valve (TRV) is fitted, close it by turning it to the minimum setting.
Having removed the air vent pin using a cloth to absorb any escaping water (3). Screw the Fernox Express injection nozzle into the air vent (after cutting to the right diameter to fit tightly (4)). Fit the tube to the adapter and screw onto the canister. Attach the other end of the tube onto the nozzle in the radiator (5).
Re-open the wheel-head valve (6) (or TRV) and inject all the content of the Fernox Express by squeezing the trigger for 30 seconds (7). After the product has been dispensed close the wheel-head valve (8) (or TRV), remove the injector nozzle and tighten the air vent pin (9). Open both radiator valves, turn on the central heating system (10) and let it run for 15 minutes to allow the Express to disperse around the system.
Fernox Express can also be for dosed via the system filling loop using the appropriate special adapter supplied with the Express product as well as via the bleed valve on a fitted Fernox TF1 Filter. The whole process takes less than two minutes.
Boiler noise results from localised boiling of the water. This happens when the inside surface of the boiler becomes too hot due to scale or baked- on sludge deposits.
All systems over five years can suffer noise and new boilers in old systems are especially vulnerable. Add Fernox Boiler Noise Silencer F2 and / or de-scale the boiler with Fernox DS40 System Cleaner and protect with Fernox Protector F1 or Protector + Filter Fluid.
One bottle of Fernox Protector F1 or Protector + Filter Fluid will treat a typical system of ten single panel radiators – double panel radiators, count as two radiators.
If the calculated dose rate is in between pack sizes, dose to the higher figure.
No, overdosing is not detrimental to the system. It is important to ensure that sufficient Protector is present in the system.
There is a test kit and a postal testing service to check the Protector concentration. Refer to Protector Test Kit product data sheet for further guidance.
Normally a treatment will last the life of the system but an annual check to determine whether further dosing is necessary is recommended.
If the system is drained, it will need to be re-treated with a further full dose of Protector. You can check if the system is properly dosed using a Fernox Protector Test Kit.
Fernox Cleaner F3 should ideally circulate around the system for at least one hour, or up to a week, after which it should be drained out and the system flushed/ cleaned before adding Fernox Protector F1 or Protector + Filter Fluid together with a Fernox TF1 Filter to protect the system from further corrosion and scale formation.
Fernox Protectors are suitable for use on systems of all ages. However, it would be advantageous to clean and flush the system with Fernox Cleaner F3 to remove sludge before adding the Protector F1.
Alternatively, the universal Fernox Filter Fluid+ Protector can deliver sludge and debris to an existing in-line filter or a newly installed TF1 Filter, whilst protecting the system against further corrosion formation.
This is an innovative, universal inhibitor package which uses the proven inhibition qualities of Fernox Protector F1 with an active dispersant.
This unique formulation is designed to detect, lift and deliver magnetic and non- magnetic debris to an in- line system filter.
Yes, Fernox Boiler Noise Silencer F2 is designed for use with any Fernox Protector.
It should be left permanently in the system with Protector F1 or Protector + Filter Fluid and replaced or topped up at the same time.
Protector + Filter Fluid should only be used in combination with an in-line system filter, which can trap and contain the debris in the system before safe removal.
It is ideal for use in circumstances where a system has previously been cleaned or flushed but subsequently has not been adequately protected so further corrosion has taken place. It is also suitable for systems with poor design or low flow rates which make conventional cleaning difficult. Protector + Filter Fluid enables ongoing purging and collection of system debris. Treatment levels should be checked annually as part of a maintenance and service programme to ensure full protection.
