Sentinel Magnetic Filter 22mm Direct Fit SENTINELVORTEX300

The Sentinel Vortex 300 is a compact magnetic filter for central heating systems, designed to capture system debris such as magnetite and sludge using a powerful magnet. It is installed on the return pipework to protect the boiler and radiators from blockages, helping to maintain heating efficiency. This is the 22mm direct fit Mark 2 version, supplied with a GB plaque, and the direct fit design allows for straightforward replacement of existing units.

• Reduced heating performance: radiators may take longer to warm up or remain cold at the bottom, indicating restricted flow.
• Visible leaks: water may be seen around the filter body or connections, which can lead to pressure loss.
• Filter not collecting debris: after cleaning, the filter may show little or no debris capture, suggesting the magnet is no longer effective.
• Noisy operation: the filter may vibrate or make unusual noises during operation, which can indicate internal damage.
• Corrosion or damage: rust or physical damage to the filter housing may be visible, risking leaks.

• Confirm the part number SENTINELVORTEX300 matches your existing filter to ensure correct replacement.
• Check that the 22mm connection is compatible with your pipework and that you have the necessary fittings.
• If replacing an existing filter, note the orientation and connections before removal to ease installation.
