The AIZO 22mm Magnetic System Filter (model SFF101) protects a boiler and central heating system from the damaging effects of contaminated system water. As water flows through the filter's redirector and into the main chamber, ferrous particles are captured by a powerful internal magnetic rod, while non-ferrous debris is trapped by a stainless-steel mesh, so cleaned water flows back into the system with the majority of harmful sludge removed.
Built with a glass-fibre reinforced PA66 main body and brass compression connections, the filter is rated to a maximum working pressure of 12 bar and a maximum temperature of 120°C, giving it a comfortable margin over typical domestic heating system conditions. Removing iron, nickel and cobalt particles from the circulating water helps protect the heat exchanger, pump and valves, supporting more efficient running and a longer service life for the whole heating system.

Competent Person Required
This filter must be installed by a competent heating engineer in accordance with good practice for central heating installations. Before fitting or servicing, isolate the electrical supply to the heating system and drain down the section of pipework being worked on.
Working Pressure vs Maximum Pressure
The filter has a working pressure of 3 bar and a maximum pressure rating of 12 bar. Typical sealed domestic heating systems operate well within this range, but installers should confirm system operating pressure is appropriate before installation.
Flush the System First
For best results, flush the heating system and add a suitable inhibitor before fitting this filter. Installing on a system already showing signs of magnetite contamination may benefit from a power flush beforehand, so the filter starts protecting a clean system rather than immediately filling with existing sludge.
Strong 9200 Gauss Magnet
A powerful internal magnetic rod rated at 9200 gauss attracts and holds iron, nickel and cobalt particles circulating in the system water, preventing them reaching the boiler's heat exchanger.
Dual-Stage Filtration
Combines magnetic capture for ferrous debris with a stainless-steel mesh for non-ferrous particles, giving broader protection than a magnet-only filter.
Durable Glass-Fibre Reinforced Body
The main body is manufactured from PA66 reinforced with 30% glass fibre, offering good chemical resistance and mechanical strength for long-term use in a heating system.
High Pressure & Temperature Tolerance
Rated to a maximum pressure of 12 bar and a maximum temperature of 120°C, comfortably exceeding the operating conditions of typical domestic heating systems.
Simple Compression Fitting
Fitted using two ball valves with 22mm compression connections, allowing straightforward isolation of the filter for cleaning without draining the whole system.
Supports System Efficiency
By keeping the heat exchanger and pump free of sludge, the filter can help reduce energy usage by up to 6% per annum, while reducing maintenance needs and extending system longevity.

What does this filter remove from a heating system?
It captures iron, nickel and cobalt particles using its internal magnetic rod, while non-ferrous debris is caught by a stainless-steel mesh, protecting the boiler's heat exchanger, pump and valves from sludge build-up.
What pipe size is this filter designed for?
This filter is designed for 22mm central heating pipework, connecting via two ball valves with 22mm compression fittings.
Can this filter handle high system pressures and temperatures?
Yes. It is rated to a maximum pressure of 12 bar and a maximum temperature of 120°C, well above the operating conditions found in typical domestic sealed heating systems.
How much energy can a system filter actually save?
Keeping the heating system free of magnetic and non-magnetic sludge can help improve heat transfer efficiency, with the potential to reduce energy consumption by up to 6% per annum compared with an unprotected, contaminated system.
Should the system be flushed before fitting this filter?
Yes, flushing the system and adding a suitable inhibitor beforehand is recommended, particularly if the system already shows signs of magnetite contamination, so the filter isn't immediately overwhelmed with existing sludge.
