Regent Twin 3072
Two 30 × 72 inch auto-backwash vessels working in alternation, linked by a single 1.5 inch twin connector. One filters while the other regenerates or holds in standby, so treated water is available at 11.8 m³/h without interruption, 24 hours a day.
About the Regent Twin 3072
A single-vessel filter has to stop treating water to backwash. The Regent Twin 3072 removes that gap. Two 30 × 72 inch vessels work in alternation: the standby vessel takes the load the moment its partner starts regenerating, so downstream plant sees continuous filtered supply.
Output quality does not shift with the backwash cycle, and the changeover creates no hydraulic shock on the main. The same vessel set runs carbon, Filtrasorb 300, Filter-AG, Filter-AG PLUS or Birm, so the duty can be matched to the raw water on site.

Typical applications
Who the Regent Twin 3072 is for
- Sites where filtered water cannot stop, even for a backwash.
- Plants that need steady output, with quality that does not change through the backwash cycle.
- Operators who want carbon or sediment duty on the same vessel set.
- Sites that later need double flow at peak: the same two vessels can be built as a duplex set.
How the Regent Twin 3072 works
The datasheet shows five steps. Raw water enters and vessel A is in service. When a set volume is reached, vessel B takes over and vessel A backwashes. Filtered water leaves uninterrupted.
The twin set alternates. Full rated flow is always drawn through one vessel, with the second held in reserve. Regeneration is triggered by measured volume rather than a clock, in delayed, immediate or combined modes.
Where the need is double flow at peak rather than uninterrupted supply, the same two vessels can be built as a duplex set on a DUPLECO15 connector, running in parallel. The datasheet says both configurations are quoted from the same sheet.
Which one should you choose?
The Regent 3072 range shares one vessel and one valve. The difference is the media inside and whether the supply can stop during backwash.
Regent Sediment 3072
You need to take silt, turbidity and suspended solids out of the water, at 11.8 m³/h on a single 30 × 72 inch vessel.
Regent Carbon 3072
You need to take out chlorine, taste, odour and organics, at 11.8 m³/h, on a single vessel with a 180 kg Centaur carbon bed.
Regent Twin 3072
You cannot stop for backwash: two vessels alternate so filtered water is available 24 hours a day at 11.8 m³/h.
Auto-Backwash Filters (smaller)
You need a smaller automatic unit, in 10 × 54 inch or 21 × 62 inch vessels with a CE 1 or CE 1.25 inch valve.
Installation and servicing
The set includes two CE 1.5 inch valve assemblies with 1.5 inch meter, DLFC and top distributor, two 30 × 72 inch tanks with adaptors, DN 50 risers and bottom stacks, the VLV15BSPT twin connector assembly, 1 inch drain fittings, power supplies, funnels and manuals. Media and the 125 kg support layer per vessel are quoted separately.
Media per vessel is 180 kg of Centaur 12×40 carbon (360 kg a set), 175 kg of Filtrasorb 300 (350 kg a set), or 367.9 L of Filter-AG PLUS, Filter-AG or Birm (735.8 L a set). The datasheet says that where more than two vessels are needed, 2 to 6 units can run from a Clack system controller.
It needs 230 V at 2 × 30 W, a drain, and 2 to 6 bar at +4 to +30 °C. The dry weight is 190 kg. The survey is chargeable and is credited back if you go ahead.
Regent Twin 3072 questions answered
What does twin alternating mean?
One vessel is in service while the other regenerates or waits in standby. The standby vessel takes over when its partner starts backwash, so filtered water never stops.
How much water does it treat?
11.8 m³/h at 1 bar differential pressure. Full rated flow is drawn through one vessel at a time, with a 15.9 m³/h backwash at 1.7 bar.
Is this double the flow of a single Regent 3072?
No. A twin set alternates, so rated flow is the same 11.8 m³/h. For double flow at peak, the datasheet describes a duplex set, which runs the two vessels in parallel.
What media can it use?
Granular activated carbon (Centaur 12×40 or Filtrasorb 300), Filter-AG, Filter-AG PLUS or Birm, so the duty can match your raw water. Media is quoted separately.
How big is it?
Two 30 × 72 inch vessels of 697 L each. The connection height is 2160 ±30 mm, the drain 2370 ±30 mm, and the dry system weighs 190 kg.
What power and pressure does it need?
230 V, 50/60 Hz, 2 × 30 W, and 2 to 6 bar at +4 to +30 °C. The inlet and outlet are G 1.5 inch and the drain G 1 inch.
Can I run more than two vessels?
Yes. Where more than two are needed, 2 to 6 units can run from a Clack system controller in progressive flow, alternator, series or random mode.
Is there a hydraulic shock on changeover?
The datasheet says the changeover creates no hydraulic shock on the main.
What warranty does it have?
The datasheet does not state a warranty period. We confirm the warranty terms at survey.
Do you supply, install and maintain it?
Yes. We supply and install it, and offer a Comprehensive Maintenance plan with consumables. The survey is chargeable and is credited back if you go ahead.

Across most of southern and eastern England, mains water is very hard. Rain filtering through chalk and limestone dissolves calcium and magnesium, and that scale coats heating elements, so we size every system to your supply and your equipment.
