A high-performance, precision-engineered in-line system filter, the TF1 Sigma Filter utilises a sealed, lidless design for increased reliability and strength. Ideal for use in restricted spaces due to its capability of being positioned in multiple orientations up to 45⁰.
This simple to install, composite plastic filter fits onto vertical and horizontal pipework, and works by allowing Hydronic Particle Separation (HPS) action to deliver contaminants to the unit’s powerful magnet assembly for safe removal.

• Pressure tested, innovative sealed unit design to maximise reliability and promote fast, easy cleaning via the drain valve
• Unique action, capturing a range of magnetic and non-magnetic debris through HPS technology
• Durable and robust construction, made from a high quality glass reinforced engineering polymer with brass on plastic manifold
• Convenient, mess-free and quick dosing via the drain valve – less time spent on-site when servicing the system
• Easy to install – fits on horizontal and vertical pipework orientation
• Will not block or restrict flow
