The Regent range is Sovereign Water's own line of commercial filtration equipment, covering carbon, sediment, multi-media and pre-filter housings for water treatment systems across the UK and the Gulf. Regent filters handle the particulates, chlorine and taste issues that a water softener does not address, sitting alongside softeners and UV systems as a complete water treatment train.
The Regent range includes the Regent Carbon 3072, Regent Sediment 3072, Regent Twin 3072, Regent Twin 3672, Regent Big Grey Filter Housings and the Regent Filter range. Each filter type addresses a different contaminant, and most commercial sites need a combination of sediment pre-filtration and activated carbon to produce water that is both physically clean and chemically safe for the applications they serve.
TL;DR
- Regent commercial filters cover carbon, sediment, multi-media and pre-filter housings
- Sediment filters remove particulates, carbon filters remove chlorine and taste issues
- Regent filters sit alongside softeners and UV systems in a complete treatment train
- 3072 and 3672 are standard commercial vessel sizes
- The right Regent filter depends on the water quality at your site

The Regent Range
The Regent series covers a broad range of commercial filtration solutions. Each model is designed for continuous operation in commercial environments and uses standard vessel sizes that simplify element replacement and maintenance.
The models are:
- Regent Carbon 3072 - Granular activated carbon filter for chlorine and taste removal in commercial drinking water systems
- Regent Sediment 3072 - Depth-filter sediment pre-filter for removing particulates down to 1-5 microns
- Regent Twin 3072 - Dual-vessel carbon or sediment filter for continuous filtration during element change-out
- Regent Twin 3672 - Higher-capacity dual-vessel system for high-throughput sites
- Regent Big Grey Filter Housings - Single-vessel filter housings for site-specific element configurations
- Regent Filters - The consumable range including sediment elements, carbon elements and pre-filters
All Regent vessels use standard commercial cartridge sizes. The 3072 and 3672 refer to the vessel diameter and length, which determines how much filter media the unit can hold and the flow rate it can handle.
What Sediment Filters Do
Sediment filters remove suspended solids from water. These include sand, silt, rust, rust scale, pipe debris, microplastics and other particulate matter that can damage downstream equipment, foul coffee machines, ice makers and espresso extracts, and reduce the effectiveness of carbon filters.
The sediment filter is typically the first stage in a treatment train. It protects the carbon filter from premature clogging and extends the life of all downstream equipment. In areas where water mains are old or where construction work causes periodic turbidity spikes, a sediment pre-filter is essential to protect the rest of the system.
The Regent Sediment 3072 uses depth-filter technology, which traps particles throughout the filter media rather than just on the surface. This gives a longer element life than surface-filter technologies and a higher dirt-holding capacity before the element needs replacing.
What Carbon Filters Do
Activated carbon filters remove chlorine, chloramines, organic compounds and taste or odour issues from water. They are essential for drinking water applications, particularly where the site serves coffee, tea, food preparation or ice machines.
Chlorine in water does not harm human health at the levels found in UK mains water, but it damages espresso machine boilers, shortens the life of ice maker components and gives coffee a flat or chemical taste. An activated carbon filter removes the chlorine to levels that protect equipment and improve taste.
The Regent Carbon 3072 uses granular activated carbon (GAC) packed into a pressure-rated vessel. GAC provides a large surface area for adsorption, which means more chlorine removal per unit of filter media and a longer element life than powdered carbon technologies.
The Regent 3072 and 3672 Systems
The 3072 and 3672 refer to the standard vessel dimensions. The 3072 vessel is 300mm in diameter by 750mm in length, and the 3672 is 365mm by 750mm. The 3672 holds more filter media and can handle a higher flow rate, making it suitable for high-throughput applications.
The Regent Twin 3072 and Regent Twin 3672 use two vessels in parallel, so that one vessel can be taken offline for element change-out while the other continues to filter. This is important for commercial sites that need uninterrupted filtered water supply.
Where Regent Filters Fit in a Commercial System
A Regent filter is usually installed after the softener in the treatment train. The softener removes hardness minerals, and the Regent sediment filter removes particulates before the carbon filter removes chlorine and taste issues. This order protects the carbon element from premature clogging by sediment.
In some cases, particularly where incoming water quality is good and hardness is low, a carbon filter alone may be sufficient for drinking water applications. But for commercial sites with high-throughput equipment like espresso machines, ice makers and steamers, the full treatment train of softener, sediment filter and carbon filter is the standard configuration.

Choosing the Right Regent Filter
Sizing a Regent filter starts with the water quality at your site. If the incoming water is high in particulates, a sediment pre-filter is essential. If the water is high in chlorine or has taste issues, a carbon filter is essential. If both are present, a sediment pre-filter followed by a carbon filter is the standard approach.
The flow rate of the site determines the vessel size. A small café with one coffee machine might handle with a single 3072 carbon filter. A large hotel with multiple coffee stations, a restaurant kitchen and an ice machine will typically need a 3672 carbon filter or a Twin system.
Maintenance and Element Replacement
Regent filter elements need regular replacement. Sediment elements typically last three to six months depending on the particulate load in the incoming water. Carbon elements typically last six to twelve months, depending on chlorine concentration and flow rate.
The replacement process involves isolating the vessel, relieving pressure, removing the old element and inserting a new one. Standard commercial elements are widely available and do not require specialist tools. The Regent Twin systems allow element change-out without interrupting the filtered supply.
Frequently Asked Questions
How often do I need to change a Regent filter element?
Sediment elements typically last three to six months. Carbon elements typically last six to twelve months. The actual frequency depends on the water quality at your site and the volume of water filtered.
Can I fit a Regent filter myself?
Regent filters use standard commercial fittings and can be installed by any competent plumber or water treatment engineer. The vessel isolation valves make element change-out straightforward without shutting off the water supply.
What is the difference between a 3072 and 3672 vessel?
The 3672 is a larger diameter vessel that holds more filter media and can handle a higher flow rate. The 3072 is suitable for lower-throughput applications. Both use standard commercial cartridge sizes.
Need Help Selecting a Regent Filter?
Choosing the right Regent filter depends on your site's water quality, flow rate requirements and the equipment you are protecting. We can test your water and recommend the correct Regent filter configuration.
