Protector F1 is the market leading inhibitor which prevents corrosion and limescale formation in central heating systems. This high performance product offers superior protection by uniquely combining three inhibitors of organic particles, which bind to the metal within the heating system to protect from debris alongside anodic inhibitors which react with the system’s metal surface to create a protective layer, and cathodic inhibitors that combine with hard water salts to form an insoluble layer. Fernox Protector F1 also includes enhanced a pH buffering to ensure the system water pH level does not drop below 6.5 or above 8.5 – the optimum pH range for preventing corrosion and limescale build-up. In line with local regulations and best practice, and for long-term protection of the system, concentration levels should be maintained and checked annually as part of the boiler or system service. Protector F1 is compatible with all other Fernox products and is suitable for use with all materials and metals used in central heating systems, including aluminium. 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.
Protects against corrosion and scale in mixed metal central heating systems to prevent breakdown and premature boiler failure
Quick and convenient – doses in 30 seconds via radiator, filling loop or Fernox TF1 System Filter – no need to drain down the system
Treats up to 130 litres of system water (16 radiators) and the equivalent of 250m2 of underfloor systems.

Product Instructions
Application
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 and 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 emptied of any collected contaminants prior to treating with the product. In single feed indirect cylinder, e.g. Primatic; or similar, potable water chemicals must be used. Fernox recommends untreated or sludged systems are thoroughly cleaned and flushed in accordance with local regulations and legislation including BS 7593:2019 and Benchmark, using Fernox Cleaner F3 Express, before treating with Fernox Protector F1 Express, as existing debris can damage the installation.
Protector F1 Express is a blend of inorganic and organic corrosion and scale inhibitors.
