The Fernox TF1 Demo Jar is a new, never-used demo Jar that is still in its original box. The box may look old, but the demo jar itself is in pristine condition. These are an amazing item, if you can actually get one ! They clearly show how bad the sludge / corrosion in a heating system can be, then show how good the magnetic filters are. One of the best ways to demonstrate to a customer, why they need a magnetic filter fitted, to protect their new boiler ! Also great to show why a power flush may be needed ! Many thanks for looking.
