Fernox Protector F1, the industry-leading inhibitor designed to combat corrosion and limescale buildup. This advanced formula delivers unmatched protection, keeping your heating system in top condition for years to come.

Superior Triple-Inhibitor Technology

Fernox Protector F1 stands out with its innovative triple-inhibitor blend, offering comprehensive protection against common central heating issues:

• Organic Particle Inhibitors: These bind to metal surfaces within the system, forming a protective shield that prevents debris accumulation and corrosion.
• Anodic Inhibitors: By reacting with the metal surfaces, these create a robust protective layer to safeguard against rust and degradation.
• Cathodic Inhibitors: These interact with hard water salts, forming an insoluble barrier that minimizes limescale formation.

This unique combination ensures your heating system remains free from damaging debris, corrosion, and scale, enhancing both performance and durability.

Optimal pH Balance for Maximum Protection

Protector F1 includes advanced pH buffering technology, maintaining system water pH levels between 6.5 and 8.5—the ideal range to prevent corrosion and limescale buildup. This ensures your system operates efficiently while extending its lifespan.

Compatibility and Ease of Use

Fernox Protector F1 is fully compatible with all metals and materials commonly used in central heating systems, including aluminium. It also works seamlessly with other Fernox products, making it a versatile choice for any setup.The Fernox Express range, including Protector F1, utilizes innovative Barrier Pressure Pack technology with a non-flammable compressed air propellant. This design ensures the product is delivered effectively without mixing with the active formula, eliminating the risk of air ingress that could lead to future corrosion.

Long-Term System Care

For optimal performance, maintain Protector F1 concentration levels and check annually during boiler or system servicing, in line with local regulations and best practices. This proactive approach ensures long-term protection and efficiency for your heating system.
