The Worcester Greenstar Magnetic System Filter 28mm (7733600237) is designed to protect central heating systems from the damaging effects of magnetic and non-magnetic debris. Over time, system water can collect contaminants such as rust and solder fragments released from radiators, pipework and boilers. These pollutants can affect system performance and contribute to damage to heating components.
Featuring a high-powered internal magnet, the Worcester Greenstar 28mm Magnetic System Filter can capture up to 500g of magnetic debris. Its magnetic and non-magnetic filtration helps collect a wide range of system contaminants, supporting cleaner system water and helping protect boilers and heat pumps. Designed with a bottom drainage point, one-way valve for adding system chemicals and an over-tightening prevention feature, it also makes routine servicing and maintenance more convenient.
