The Worcester Greenstar System Filter has been optimally manufactured to combat the damaging effects of system debris and pollutants, by capturing contaminants before they reach your boiler.
Over time, the water in your central heating system accumulates harmful dirt and debris, for example rust and solder fragments that have been shed by radiators and boilers.The system filer features a high powered internal magnet that can capture up to 300g (22mm) of magnetic debris.
