The Fernox TF1 Sigma Mini 22mm Magnetic System Filter is a compact, high-performance heating system filter designed to protect boilers from the damaging effects of circulating corrosion debris.
With its ultra-compact design, the TF1 Sigma Mini is ideal for installations where space around the boiler is restricted. It can be installed on horizontal or vertical pipework and requires as little as 105mm of clearance, making it suitable for fitting directly below a boiler or in other tight spaces.
The filter uses a powerful neodymium magnet to capture sludge, magnetite and other system contaminants while engineered internal flow paths help maintain low pressure loss. The sealed design also allows quick and controlled cleaning through the drain point without dismantling the filter.
The TF1 Sigma Mini is supplied with a 22mm slip-socket connection and is backed by a 10-year warranty from Fernox.
