    • Description
    • Additional information
    • Delivery

    The Fernox F3 Express Cleaner provides a fast and effective way to clean central heating systems without draining. It removes sludge, debris, and installation residues that restrict flow and reduce efficiency. As a result, heating systems regain performance quickly and reliably.

    Modern heating systems require regular cleaning to maintain efficiency. Therefore, Fernox Express Cleaner offers a practical solution for installers and service engineers.

    What Is Fernox F3 Express Cleaner?

    Fernox F3 Cleaner is a high-performance system cleaner delivered in an aerosol format. It contains the same trusted F3 cleaning formulation but allows faster application without pumps or dosing equipment.

    Consequently, engineers can clean systems during routine servicing with minimal disruption.

    How Fernox F3 Express Cleaner Works

    Once injected into the system,  F3 Express Cleaner circulates with the heating water. It breaks down sludge, grease, and particulate debris. Therefore, contaminants remain suspended until flushing removes them.

    Because the cleaner distributes evenly, it reaches radiators, pipework, pumps, and heat exchangers.

    Key Benefits of Fernox F3 Express Cleaner

    Rapid Aerosol Application

    F3 Express Cleaner uses an aerosol delivery system that allows quick injection through a radiator or filling point. As a result, installation time reduces significantly.

    Removes Sludge and Debris

    The cleaner dissolves iron oxide sludge and installation residues. Therefore, it restores circulation and improves heat transfer efficiency.

    Suitable for All Heating Systems

    Fernox F3 Cleaner suits sealed and open-vented systems. In addition, it works safely with aluminium radiators and plastic pipework.
