Filters for silt, rust and stale tank water.
In Oman, what needs filtering depends on the source. Coastal buildings on Nama's desalinated water collect rust and sediment in their tanks and pipes. Villas and farms on a well draw up sand and silt. Regent clears both at the inlet, from simple cartridge housings to self-cleaning vessels for large plant rooms.
Small housing, big vessel or a twin set.
Size and upkeep decide it. Once we know your source and your busiest hour, we confirm the model and the media inside it.
Homes, small cafes & shops
Inlet housings for standard 4.5 inch cartridges. We load sediment, carbon or another media to suit a tank-fed flat or a well-fed villa.
- Up to 5.0 m3/h
- 4.5 × 10" or 4.5 × 20" cartridges
- 1" connections
- Cartridge change every 6 to 12 months, typically
Hotels, hospitals & larger sites
A 30 × 72 inch vessel with a metered CE 1.5 inch valve. The bed backwashes itself, so there are no cartridges to change.
- Service flow 11.8 m3/h
- 697 L vessel
- Backwash by metered volume
- Sediment, carbon or Birm media
Sites that can't go without
Two vessels share the work. One filters while the other cleans or waits, so filtered water never stops.
- 11.8 m3/h at any hour
- Changeover without pressure shock
- Five media choices
- 2 to 6 units on one Clack controller
Four filters, flat to hospital.
Every Regent, side by side.

Different water, different filter.
Regent removes particles and off-tastes before they reach your taps and equipment. Flow and how much attention you want to give it decide the method.
Cartridge housing
Regent Big GreyThe water passes through a cartridge picked for your source. When it is spent, it is swapped for a new one.
- Sand and well silt
- Chlorine taste and smell (carbon cartridge)
- Cloudy or coloured water
Why it matters: The simple, low-cost choice for a home or small shop.
Sediment vessel
Regent Sediment 3072A deep bed of Filter-AG traps particles all the way down. On a metered schedule, backwash lifts the bed and flushes the dirt away.
- Silt and turbidity
- Rust and suspended solids
- Iron and manganese (Birm media)
Why it matters: Softeners, RO membranes and pumps after it stay clean.
Carbon vessel
Regent Carbon 3072Activated carbon holds on to chlorine and organic compounds as water flows through. Backwash settles the bed again so nothing short-cuts it.
- Chlorine and chloramine
- Musty tank taste and smell
- Dissolved organics
Why it matters: Chlorine damages RO membranes and resin, so carbon comes before them.
Filtering does not soften or disinfect water. Hard inland water needs a Regal softener, and a well or falaj supply should finish with SovSafe UV.
Cleaner water and longer-lasting kit.
Less wear
- Taps and valves keep working
- Longer RO membrane life
- Softener resin kept clean
- Pumps and heaters protected
Better to drink
- No sandy or cloudy water
- No stale or chlorine taste
- Better coffee and tea
- Clearer ice
Easy to run
- 3072 vessels backwash themselves
- Started by water used, not by a clock
- Proven Clack valves
- Serviced by our Oman partner
The same engineering at every size.
Each Regent model uses proven valves and standard media, so a villa in Seeb and a hospital plant room get the same quality, sized to their flow.
- Media matched to your well or tank
- The first stage before Regal, RO and UV
- Twin sets where water can't stop
- Maintenance plan from a fixed annual fee

Regent in Oman
Desalinated water in coastal Oman leaves the plant clean, then sits in roof and ground tanks. Those tanks, and the pipes after them, are where sand, rust and stale tastes get in. Well water inland can bring sand of its own.
Regent catches it at the inlet. Big Grey cartridge housings suit flats, villas and cafés, and the 3072 media vessels serve hotels and larger buildings.
Common questions
Where does the grit in our water come from?
Usually the tank or older pipework. A sediment stage at the inlet traps it before it reaches taps and machines.
Does Regent soften or purify?
No. It removes particles, taste and chlorine. Hardness needs a softener, and dissolved solids need reverse osmosis.
What suits a whole apartment block?
The 3072 vessels, after the building tank. One flat can manage with a Big Grey housing.
Specified, installed and looked after anywhere in Oman
Coastal mains water is mostly desalinated seawater. It is soft, but it picks things up in pipes and tanks. Inland wells can be very hard: one 2024 study of Al Dhahirah groundwater found an average hardness of 659 mg/l.
Say which governorate you are in, whether the water comes from the Nama network, a tank or a well, and what you need it for. We design the system, price it in rials and arrange the fit.
