High Efficiency Magnetic Filtration: Externally threaded DN20/3/4 magnetic filter for floor heating filters uses a radial separation mesh to trap scale, rust and sediment before they circulate, improving HVAC performance and extending system life. The large internal chamber slows water flow, facilitating gravity settling for more thorough pre-filtration. Integrated Magnetic Purification System: Boiler wall filters include a removable magnetic ring housed within the magnetic purification chamber, attracting ferrous particles to the interior wall of the storage tank.This design ensures debris stays out of the water loop, promoting consistent heating efficiency and preventing damage to sensitive components. Robust material and precise construction: The pre-filters are made from engineering plastic and brass, with a stainless steel filter cartridge that stands up to daily use. Rated for temperatures from 0 to 75°C and pressures from 0.1 to 0.16 MPa, the magnetic filters provide long-lasting performance in various HVAC applications while maintaining stable water flow.
[User-friendly drain function]: The floor heating filters incorporate a bottom drain valve, allowing direct discharge of collected water and impurities during operation without disassembling the device.This quick access feature reduces maintenance time, supports continuous operation of the heating system and maintains filtration performance at maximum levels. Versatile Compatibility and Targeted Application: DN20/3/4 magnetic filters connect via 25mm threaded interface, suitable for common wall-mounted boilers with non-corrosive water medium. The single-stage unidirectional output design focuses on the efficient removal of magnetic impurities, making the unit perfect for pre-filtering underfloor heating systems and preserving long-term reliability.
