The Fernox TF1 Sigma UB Filter is a compact filter system, designed to be installed horizontally under a boiler where there is restricted space with concealed pipework. It has been manufactured from a high strength engineering grade polymer, ensuring the filter is durable and robust. The filter has been designed so it won’t block or reduce flow through the pipework or impact the heating system, while still capturing a wide range of system contaminates that can reduce the lifespan of your heating system. The Fernox TF1 Sigma UB Filter also comes with an easy-to-reach three-way valve with filter isolation and cleaning functionality. Combine these great features with the 10-year warranty, and you have a long-lasting product that will keep energy bills low for as long as possible, and help reduce issues with your heating system, making it a cost-effective investment.
