Typical applications
Regent Big Grey Filter Housings in Saudi Arabia
Water that has spent a summer in a Riyadh roof tank can carry sediment and taste. A Big Grey housing filters it as it enters the house, so every tap benefits.
Housings take 4.5 × 20 or 4.5 × 10 inch cartridges and run at 2 to 6 bar.
Common questions
Does it work on well water?
Yes. It is rated for tap, well and rainwater.
Will it protect my softener?
Yes. Catching sediment first keeps softener resin and RO membranes cleaner for longer.
What flow does it give?
Up to 5 m³ an hour.
Supplied, installed and serviced in Saudi Arabia
Saudi supply is a mix of desalinated water and groundwater. Where groundwater is blended in, as in Riyadh, the water can be hard enough to scale heaters and machines, so we check your supply before choosing a system.
Tell us your city, whether the site is on mains or tanker water, and what the system is for. We specify it, quote in riyals and install it.
