Product Uses
Fernox Central Heating Protector F1 Express is an aerosol product designed to make dosing a central heating system quick and simple with no mess or inconvenience to the user. As with all Fernox inhibitors, Protector F1 Express provides long term protection of domestic central heating systems against internal corrosion and limescale formation. It prevents corrosion of all metals found in these systems i.e. ferrous metals, copper and copper alloys and aluminium. It is suitable for all types of boiler, radiator and pipe work systems. Fernox Protector F1 Express is compatible with all metals and materials commonly used in central heating systems.
For continued long-term protection we recommend Protector F1 levels are checked regularly (annually). The concentration of the product can be easily measured on site using a Fernox Protector Test Kit or 60 Sec Protector Check Strip.
Application and Dosage
One 265ml can will protect an average sized system (100 litres or up to ten single radiators) and is added via a radiator or filling loop. Fernox Protector F1 Express can be dispensed directly into a radiator air vent or system filling loop using the appropriate special adapter supplied with the product
In single feed indirect cylinder, e.g. 'Primatic' or similar, potable water chemicals must be used.
