Keston 22mm System Filter is a magnetic filter designed to protect domestic central heating systems against the damaging effects of contaminants, sludge or debris.
Keston 22mm System Filter: Features & Benefits
This filter has been specifically crafted for use with Keston Combi and System boilers, extending the warranty of both boilers from 5 to 7 years† as it improves overall efficiency of the heating system. In turn, installing a system filter also reduces boiler running costs.
Keston 22mm System Filter works by ensuring any build-up of sludge or debris does not block your heating system and cause damage to the boiler. The filter attracts contaminants and removes them from the system, ensuring only clean water is circulated back to the boiler.
The compact design is easy to install thanks to rapid fit connectors and a quick release trigger, making the filter quick and easy to remove and reinstall when undertaking annual servicing or a system flush. It fits on horizontal or vertical pipework in both flow directions and is capable of both non-magnetic and enhanced magnetic capture.
Used either as a combi boiler filter or magnetic system filter, Keston 22mm System Filter is a must-have twin flue boiler accessory.
