Cleaner F3 is an effective, universal pH neutral, non-foaming cleaner which removes sludge, scale, and debris from existing central heating systems to restore heating efficiency and eliminate boiler noise. When commissioning new systems in accordance with local regulations and best practices, Cleaner F3 is ideal for removing flux residues and other installation debris to help extend the life of the boiler and the efficiency of the system. The Fernox Express range uses Barrier Pressure Pack technology and compressed air propellant to expel the product, so the entire range is non-flammable. The propellant (compressed air) is not mixed with the active product, so there is no risk of air ingress into the system, which could accelerate the future risk of corrosion.
Please always refer to the manufacturer’s instructions for the correct application. All parts should be fitted by a qualified plumber.
