22mm Magnetic Boiler Filter – 10,000 Gauss Central Heating Magnetic Filter with Isolation Valves – Inline Boiler Sludge Filter for Heating Systems
- High‑performance magnetic filtration — Engineered to capture magnetite sludge, rust and metallic debris circulating through central heating systems, helping protect boilers, pumps and valves while improving overall heating efficiency.
- 10,000‑gauss ultra‑strong magnet — A powerful internal magnet housed in a dry pocket traps iron‑oxide particles before they settle, reducing sludge build‑up in radiators, pipework and boiler components.
- 22mm system compatibility — Designed to fit standard 22mm central‑heating pipework, making it suitable for combi boilers, sealed systems and traditional domestic heating installations.
- Durable high‑temperature construction — Built from high‑strength PA66 and robust POM components for long‑term reliability. Rated for operating temperatures from 5°C to 85°C and pressures up to 6 bar.
- Easy installation & servicing — Supplied with brass isolation valves, drain‑off point, service spanner and spare O‑rings. The removable magnet allows quick cleaning without draining the entire system.
