F9 Protector+ Inhibitor & Filter Fluid, 1 pt

Designed for use with Fernox TF1 in-line system filters or other similar filters, this unique inhibitor package includes an active dispersant which is proven to aid the safe collection of corrosion, debris and scale via a filter. The Protector+ Filter Fluid F9 enhances the performance of a system filter whilst offering full protection against corrosion and scale formation. This innovative, proven formulation also extends system life and maintains optimum efficiency, while still being an environmentally friendly formulation. Concentration levels should be checked as part of the annual maintenance system service.

The recommended ‘in use’ concentration of Protector+ Filter Fluid F9 is 0.385%. A single dose treats and protects a larger sized property with a heating system of 130 litres, up to 16 radiators or 250 sqm of underfloor heating. For open vented systems add via the feed and expansion tank. For sealed systems add via a suitable dosing point (e.g. a towel rail, or an in-line system filter). Alternatively, use a suitable dosing vessel to inject the product into the system. In single feed indirect cylinders, e.g. ‘Primatic’ or similar, potable water chemicals must be used. We recommend that untreated, or sludged systems are thoroughly cleaned and flushed in accordance with BS 7593:2019 and Benchmark using Fernox Cleaner F3/F8, before treating with Fernox Protector+ Filter Fluid F9, as existing debris can damage the installation.
