• Compact Under Boiler Design: Engineered to fit directly beneath boilers where space is limited helping maintain a clean installation without bulky pipework adjustments
• Magnetic Sludge Removal: High-strength magnet captures magnetite and circulating debris helping protect boilers pumps and valves from internal wear and blockages
• Check Compatibility: Designed for 22 mm pipework and suitable for selected boilers only this under boiler filter is not a universal fit please check compatibility list before purchase
• Supports Heating Performance: Helps reduce sludge build-up that can restrict water flow supporting improved heat distribution and more consistent radiator output
• Easy Installation and Maintenance: Designed for straightforward fitting and simple cleaning access without requiring a full system drain down saving time during servicing

Composite under boiler system filter with a brass manifold designed for easy installation in small, restricted areas and with concealed pipework. This high-performance filter can be installed directly under the boiler or in restricted spaces due to the compact, versatile design. The TF1 Sigma UB Filter offers the ultimate in installer choice and provides high efficiency protection against the build-up of system debris. A high capacity, compact design Ideal for use in restricted spaces. The TF1 Sigma UB Filter body is constructed from a high strength engineering grade polymer, suitable for heating and cooling system applications. The filter manifold is constructed from a premium grade, non-porous forged brass, allowing for direct connections onto the system, and a simple servicing procedure via the precision engineered manifold.The TF1 Sigma UB Filter has been designed to ensure there is minimal pressure loss in addition to maintaining a high collection efficiency. The filter has been designed to capture a range of system contaminates, whilst also ensuring it cannot block, reduce flow through pipework or impact the performance of the heating system. The three-way ball valve has been designed to allow users to easily operate by hand, whilst also providing a reliable serving procedure. The filter manifold includes a secure connection to the system and a robust service point allowing the filter to be drained and cleaned. The magnet is made using premium grade neodymium, enabling a high efficiency capture rate, as well as a robust filtration medium that will ensure a continued and consistent level of collection
