Protector F1 is the market leading inhibitor which protects against corrosion and limescale formation in domestic central heating systems. Protector F1 is suitable for use with all metals and materials commonly used in heating systems. For long-term protection ensure concentration levels are maintained and checked annually as part of the boiler or system service. Protector F1 is compatible with all other Fernox products.
The recommended ‘in use’ concentration of the product is 0.5%. One 500ml bottle will treat an average 3 to 4 bedroom house (100 litres). For open vented systems add via the feed and expansion tank. For sealed systems add via the radiator using a Fernox Injector. In single feed indirect cylinders, e.g. “Primatic” or similar, potable water chemicals must be used. For continued protection Fernox Protector F1 levels should be checked regularly (annually).
