28mm Magnetic Filter

The 28 mm Inline Magnetic Filter is a high-performance system protection filter designed to safeguard central-heating and heat-pump systems from circulating debris. Engineered for direct inline installation, it efficiently captures magnetic and non-magnetic contaminants to help maintain system efficiency, reliability, and longevity.

Featuring a powerful internal magnet, the filter removes magnetite sludge and fine iron particles that can cause blockages, reduce heat transfer, and lead to premature component failure. Its compact inline design makes it ideal for installations where space is limited, including air source heat pump primary circuits.

Supplied with full-bore isolation valves, the filter can be serviced quickly and cleanly without draining the system. The robust, corrosion-resistant body ensures long-term durability, while the bottom drain point allows for simple debris removal during routine maintenance.
