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 45 degrees.

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.
