Fernox Protector F1 is the top-rated inhibitor for preventing corrosion and limescale in central heating systems. This advanced formula provides superior protection, ensuring long-term efficiency and durability for your heating setup.

Superior Triple-Inhibitor Technology

Fernox Protector F1 features a unique blend of three inhibitors for comprehensive system defense:

• Organic Particle Inhibitors: Bind to metal surfaces, creating a shield against debris buildup and corrosion.
• Anodic Inhibitors: React with metals to form a durable layer that prevents rust and wear.
• Cathodic Inhibitors: Combine with hard water salts to create an insoluble barrier, reducing limescale.

This combination keeps systems free from debris, corrosion, and scale, boosting performance and longevity.

Optimal pH Buffering

With enhanced pH buffering, Protector F1 maintains water pH between 6.5 and 8.5—the perfect range to avoid corrosion and limescale, promoting efficient operation and extended system life.

Compatibility and Application

• Fully compatible with all central heating metals and materials, including aluminium.
• Works seamlessly with other Fernox products.
• Part of the Fernox Express range, using Barrier Pressure Pack technology with non-flammable compressed air propellant to prevent air ingress and future corrosion risks.
