Developed for use with the Fernox TF1 filter range and in-line system filters. Fernox F9 Filter Fluid+ Protector is specifically formulated to lift corrosion deposits and contaminants within central heating systems to deliver the debris directly to an in-line filter (such as one from the Fernox TF1 Filter range) for fast removal and containment. Importantly, it also provides the long-term protection of domestic central heating systems against internal corrosion and limescale formation.
