The CM-3 magnetic filter was designed to provide a quick and easy way of removing all suspended iron oxide. It improves boiler efficiency and optimises energy output. The filter protects the boiler and the entire heating circuit, extending their life. Once installed, the CM-3 will immediately protect and clean the entire network. Thanks to a system of unscrewing parts and plugs, the CM-3 can be positioned in the direction most suited to the boiler or heating system.
