Our 2-Way 360 degree diverter has all the options covered! Boiler-m8 know that time is money. Regardless of whether it's a new install or a retrofit installation, our rotating 2-Way Diverter gives you more options than some other filters on the market. Filter supplied with plastic diverters are not as robust and also break the earth continuity of a system, that's why Boiler-m8 only ever use Brass diverters on ALL our filters! Full Flow Design available with 22mm or 28mm PN20 Isolation Valves All Boiler-m8 filters are designed to be system friendly. Our technical experts have ensured that the advanced design features allow effective removal of system debris, whilst minimising pressure loss. Standard Bore valves supplied with other filters significantly reduce the flow rate, causing damage to the boiler and circulating pump as well as reducing system efficiency. The Defender-2 is available with either 22mm or 28mm PN20 rated high pressure isolation valves with twin valve stem seals. Simple Servicing & Maintenance EZY-Clean Removable Magnet Stack Normally installed to the return flow after the last radiator, system water is diverted through our 2-way 360 degree diverter into the filter body. Our filter design reduces the flow of water allowing the high strength EZY-Clean removable magnet stack and particulate filter to remove both magnetic and non-magnetic debris from the system. Thanks to advanced design and gravity, non-magnetic debris falls out of suspension and is collected in the high capacity body, leaving the EZY-Clean removable magnet stack to do its job. Simple Servicing & Maintenance Dosing the heating system with inhibitor or cleaner is a no longer a time consuming affair. Simply turn the easy grip isolating valves and add the chemical directly in to the filter body through the air vent port, then turn back on the isolating valves - it's as simple as that! All Boiler-m8 filters are supplied with a manual air-vent installed.

Specification Details Review: Great Product _ Great Value - Really good product. I swapped out a a Fernox TF1 which is 3 times the price of this one. Same fittings, insert size and it was an easy fit/ replacement. A* Review: Works well and simple to install and use - Good quality parts. Straightforward to fit and maintain with no leaks. The two isolation valves are easy to operate for cleaning out. Heavy particles collected by the filter can be emptied out first. Magnetic particles can be released by withdrawing the strong magnet. An impressive amount of crud was collected in a bucket after only a few days. ## Features - Perfect filter: A remarkably versatile central heating filter made to address the issues brought on by magnetic system sludge. - Defender for Heating system: The new Boiler-m8 magnetic system filters offer your heating system by combining high strength magnetic and stainless steel particle filtration - Sludge Filtration: To preserve central heating systems in good condition and boost overall efficiency, Boiler-m8 central heating system filters remove sludge. This is accomplished by preventing the accumulation of sludge in radiators by the effective removal of system debris - Water tight seal: Our special 2-Way 360-degree Brass diverter body connection includes dual telescopic seals that can be turned while under pressure for simple maintenance, and our full-flow isolating valves have flat-faced unions and high pressure ratings to assure a watertight guarantee. - How it works: Our 2-way 360-degree diverter directs system water into the filter body. Due to the reduced water flow created by our filter design, both magnetic and non-magnetic debris can be removed from the system using the high strength EZY-Clean disposable magnet stack and particle filter. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B09TLCK1LG | | Best Sellers Rank | 235,001 in DIY & Tools ( See Top 100 in DIY & Tools ) 1,879 in Central Heating System Accessories | | Brand | Boiler-m8 | | Brand Name | Boiler-m8 | | Compatible Devices | heaters | | Compatible devices | heaters | | Customer Reviews | 4.4 out of 5 stars 96 Reviews | | Included Components | Isolating Valves and Spanner | | Item Dimensions L x W x Thickness | 23L x 13W x 8Th centimetres | | Item Type Name | Boiler-m8 Defender-2 Central Heating Magnetic System Boiler Filter and Inline Full Bore Valves | | Manufacturer | Boiler-m8 | | Manufacturer Part Number | 150-4037 | | Material | PA66 Polymer | | Material Type | PA66 Polymer | | Model Number | Defender-2 | | Number of Items | 1 | | Number of items | 1 | | Product Grade | new | | Product Warranty | 5 year manufacturers warranty. | | Product dimensions | 23L x 13W x 8Th centimetres | | Unit Count | 1.0 count | ## Product Details - **Brand:** Boiler-m8 - **Compatible devices:** heaters - **Manufacturer:** Boiler-m8 - **Material:** PA66 Polymer - **Number of items:** 1 - **Product dimensions:** 23L x 13W x 8Th centimetres - **Product grade:** new - **Unit count:** 1.0 count ## Images ![Defender-2 Central Heating Magnetic System Boiler Filter and Inline Full Bore Valves for Sludge Removal 22mm - Image 1](https://m.media-amazon.com/images/I/31z24rBli7L.jpg) ![Defender-2 Central Heating Magnetic System Boiler Filter and Inline Full Bore Valves for Sludge Removal 22mm - Image 2](https://m.media-amazon.com/images/I/41GHFzMUmgL.jpg) ![Defender-2 Central Heating Magnetic System Boiler Filter and Inline Full Bore Valves for Sludge Removal 22mm - Image 3](https://m.media-amazon.com/images/I/61+kmyQgLsL.jpg) ![Defender-2 Central Heating Magnetic System Boiler Filter and Inline Full Bore Valves for Sludge Removal 22mm - Image 4](https://m.media-amazon.com/images/I/51zn3V+KpLL.jpg) ![Defender-2 Central Heating Magnetic System Boiler Filter and Inline Full Bore Valves for Sludge Removal 22mm - Image 5](https://m.media-amazon.com/images/I/311vAKS0fRL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great Product _ Great Value *by K***K on 15 September 2025* Really good product.
