Filter Pot Mini
Key Information
The BSP Filter Pot Mini is a high-capacity side stream filtration and dosing unit designed to maintain water quality and protect commercial heating and cooling systems from the harmful effects of magnetite, debris, bacteria and entrained air. Suitable for systems up to 90,000 litres, the Filter Pot Mini combines magnetic filtration, ultra-fine particulate removal, passive deaeration and chemical dosing within a compact stainless steel assembly.
Designed in accordance with BSRIA BG29 and BG50 guidance, the unit continuously removes both magnetic and non-magnetic contaminants from circulating system water, helping to improve system efficiency, reduce maintenance requirements and extend the lifespan of boilers, chillers, pumps and associated equipment.
The Filter Pot Mini incorporates four high-strength 8,500 Gauss neodymium magnet bars alongside BSP’s Anti-Microbial spun cartridge filters, available in filtration ratings from 50 micron down to 0.5 micron. The silver ion impregnated filter media helps inhibit bacterial growth and biofouling within the system while delivering exceptional dirt removal performance.
Manufactured from durable 304 and 316 stainless steel components, the unit is designed for simple installation, easy servicing and long-term reliability. The integrated 5.5 litre dosing pot allows water treatment chemicals to be safely introduced without shutting down the system, while the automatic air vent continuously removes microbubbles and trapped air to help minimise noise, corrosion and system stress.
Its intelligent internal design ensures uninterrupted system performance, even during extended servicing intervals, making the Filter Pot Mini an effective long-term solution for maintaining clean and efficient closed-loop systems.

Further Information
| Feature | Description |
|---|---|
| Compliance | Fully compliant with BSRIA guidelines BG29 and BG50 for side stream filtration, chemical dosing, corrosion inhibitor treatment, magnetic filtration, passive deaeration, fill water pre-treatment, solids removal and filtration, bacteria and bio-fouling inhibition, CPD dynamic filling, maintenance and inspection, dynamic flushing procedure and on-line cleaning. |
| Magnetic Filter | Removes magnetic system debris before reaching the Cartridge Filter below, helps to increase the lifespan of the boiler, chiller and cooling system components, reduces carbon emissions, increases fuel efficiency and increases the lifespan of the Cartridge Filter. |
| Anti-Microbial Nylon Cartridge Filter |
BSP’s Anti-Microbial Spun Cartridge Filters remove non-magnetic system debris, available in 50, 20, 5 and 0.5 micron filtration rates, ensures coalescence micro-bubble formation on the surface of the Filter and surpasses BSRIA guidance for filtration rates. They are typically used in instances when the water has a heavy degree of particles. BSP Cartridge Filters can catch and hold a large volume of particles before they become clogged. The nylon filtration media is impregnated with Silver Ions which block the bacterial respiratory system of bacteria thereby destroying the energy production of the cell, leading to the bursting of the cell membrane and neutralising of the bacteria. Max working temperature is 110°C. |
| Automatic Air Vent | Ensures the system micro-bubbles and air are emitted from the system, helps reduce noisy pipework and decreases stress on system components. |
| 5.5L Dosing Pot Capacity | Enables installers and maintenance personnel to quickly dose the system with water treatment chemicals. |
| 1″ BSP Dirty Flow and Clean Return Connections | Suitable for all types of LTHW heating and cooling water systems up to 90,000 Litres in volume. |
| 1/2″ BSP System Fill and Drain Connection |
Using the System Fill feature with the BSP Anti-Microbial 0.5micron Cartridge reduces the possibility of bacteria, dirt and debris entering the system. Further, the fill feature can also be used to add larger volumes of inhibitor when an external pump is required for dosing. The dedicated ½” Drain Connection ensures the system water is drained from the vessel during filter cleaning, leading to faster filter replacement time. |
| 4No 8,500 Gauss Neodymium Magnet Bars | Each magnet is fully encased in a 304SS shell, easily removable from the 316SS Magnet Grate for cleaning and fully submerged into the system flow for increased filtration. |
| Installation | Complete with backing plate for simple installation to wall or frame (4 x M12 holes) |
| Servicing | The cleaning of the filters can be simply achieved without the need to shut the main system down and the dosing of water treatment chemicals is achieved simply and safely, again without the need to shut the system down. |
| Unblockable System | Even if the filters are never serviced the ingenious design ensures that the filter will not inhibit system performance. |
| Stainless Steel Components | All components are manufactured from 304SS or 316SS for easy cleaning and servicing of the the filter. |
| Pressure / Temperature Gauge | A 0-10 Bar pressure and 0-120°C temperature gauge is included on the front of the vessel to give extra reassurance that the vessel is empty and safe to open and remove the lid before cleaning the filters. |
| Polished Inner Surface of Vessel | The inner surface of the Vessel is highly polished to remove any crevices.Metal ‘eating’ bacteria habitate crevices within pipework. |
| Full Bore Flat Face Isolation Valves | The 304SS isolation valves do not restrict system flow and increases ease of installation. |
| Bespoke Insulation Jacket | The bespoke insulation jacket ensures heat loss is minimised. |
| Warranty | 10 years from date of first installation (refer to the warranty document). |
