Salus Controls 22mm Salus Filter MD22S

Salus MD22S Inline Magnetic Filter

Protect your central heating system and maintain efficient performance with the Salus MD22S Inline Magnetic Filter. Designed to capture harmful magnetic and non-magnetic debris circulating through heating pipework, this high-performance filter helps prevent sludge build-up, protect vital components and extend the working life of your boiler and heating system.

Featuring a powerful removable magnet and a compact, easy-to-service design, the Salus magnetic filter provides reliable protection for central heating installations, including compatible wet underfloor heating systems.

Key Features and Benefits

• Effective System Protection: Captures harmful iron oxide particles, sludge and other debris to help prevent blockages and damage to heating components.
• Improved Heating Efficiency: Helps maintain efficient water circulation and heat transfer by reducing the build-up of unwanted contaminants.
• Powerful Magnetic Filtration: Features an ultra-strong neodymium magnet to attract and retain magnetic particles circulating within the system.
• Protects Boiler Components: Helps reduce wear and the risk of debris-related problems affecting boilers, pumps and other heating equipment.
• Easy Installation: Inline connections and supplied isolation valves simplify fitting into compatible heating pipework.
• Simple Maintenance: Removable magnet, integrated air vent and drain valve allow convenient cleaning and servicing.
• Flexible Installation: Suitable for installation on horizontal or vertical pipework, providing flexibility in different heating system layouts.
• Compact Design: Ideal for installations where available space is limited.
• No Electrical Supply Required: Operates continuously during normal heating system circulation without electricity or additional running costs.
• 5-Year Manufacturer's Warranty: Provides added confidence in product quality and reliability.

Suitable Applications and Compatibility

The Salus MD22S magnetic filter is designed for use within compatible domestic central heating systems, helping protect the circulating water circuit against contamination.

• Domestic boiler-fed central heating systems.
• Wet underfloor heating installations connected to a compatible central heating circuit.
• Radiator heating systems.
• Combined radiator and wet underfloor heating systems.
• Suitable sealed and open-vented central heating systems.
• New heating installations and upgrades to existing systems.

The filter is particularly beneficial in systems where corrosion particles and circulating sludge could affect heating performance or the reliability of pumps, valves and other components.

Role in Wet Underfloor Heating

Maintaining clean circulating water is important for the long-term performance of a wet underfloor heating system. Over time, corrosion within metallic heating components can produce iron oxide particles, commonly known as magnetite or black sludge.

When these contaminants circulate through a heating system, they can accumulate in pumps, valves, manifolds and other components, potentially restricting water flow and reducing efficiency.

The Salus MD22S helps capture these contaminants within the main heating circuit before they can cause unnecessary wear or blockages. This supports reliable circulation, consistent heating performance and improved protection of the wider heating installation.

Installation and Maintenance Guidance

For effective protection, the Salus MD22S is generally recommended for installation on the primary return pipework before water re-enters the boiler. This positioning helps capture circulating debris before it reaches sensitive boiler components.

• Install in accordance with the manufacturer's instructions and the direction of water flow.
• Ensure sufficient clearance around the filter for inspection, cleaning and maintenance.
• Use the isolation valves to isolate the filter safely during servicing.
• Remove and clean the magnetic assembly periodically to maintain effective filtration.
• Use the integrated air vent and drain valve as directed during commissioning and maintenance.
• Check seals and connections during servicing to maintain a watertight installation.

Installation and servicing should be carried out by a competent heating professional. The magnetic filter should be used alongside appropriate system flushing, water treatment and maintenance practices rather than as a replacement for them.
