The Fernox Total Filter TF1 is simple to fit, removes sludge and takes only seconds to clean in-line without the need to remove or dismantle the unit. This in-line filter uses a unique hydrocyclonic and magnetic action to remove and contain both magnetic and nonmagnetic contaminants from central heating systems. It can be connected directly onto 1-inch sweat pipe work vertically or horizontally, using the valve fittings provided, and is positioned flush to a wall in existing pipe work, even in hard to reach areas.
