Cuno CFS8112-S Filter Cartridge Oman - 1 micron scale inhibitor replacement cartridge

The Cuno CFS8112-S filter cartridge Oman is the genuine 3M Water Filtration replacement cartridge for CUNO 8000-series foodservice filtration heads, combining 1-micron graded-density carbon filtration with a scale inhibitor in a single sanitary quick-change body. It is built for ice machines, espresso machines, combi ovens and beverage dispensers running on Muscat’s mains supply, where hardness and chlorine shorten equipment life faster than most operators expect.

What the Cuno CFS8112-S Filter Cartridge Oman Removes

Oman’s municipal and blended groundwater typically carries elevated hardness along with residual chlorine from disinfection. The CFS8112-S targets both problems at once:

Chlorine taste and odour, so coffee and ice taste clean
Sediment, rust and particulate down to 1 micron nominal
Scale formation on boiler elements, evaporator plates and steam generators, through controlled polyphosphate feed
Cloudiness and off-flavours carried over from ageing building pipework

The scale inhibitor is the reason this cartridge is specified over a plain carbon block. Instead of removing hardness, it sequesters calcium and magnesium so they stay in solution and pass through the machine rather than plating out on hot surfaces. That keeps ice production rates stable and cuts descaling call-outs.

Installation, Replacement and Warranty

The cartridge twists into an existing CUNO 8000-series head in under a minute with no tools and no need to break the plumbing. Flush the new cartridge for five minutes before returning the machine to service. Replace at 10,000 gallons or every six months, whichever comes first. On Oman’s harder supplies we generally recommend the six-month interval regardless of throughput, and we can put your site on a scheduled replacement plan so it is never missed.

Every cartridge is supplied with the manufacturer’s warranty against material and workmanship defects. Our technicians handle installation and commissioning across Muscat if you would rather not do it in-house.

Cuno CFS8112-S Filter Cartridge Oman: Frequently Asked Questions

What is the difference between the CFS8112-S and the CFS8112?
The “-S” suffix denotes the scale inhibitor version. Both filter to 1 micron and remove chlorine taste and odour, but only the CFS8112-S feeds polyphosphate to control limescale, which is what you want on Oman’s hard water.

Will it fit my existing filter head?
Yes, if the head is a CUNO 8000-series quick-change fitting. Send us a photo of the head on WhatsApp and we will confirm before you order.

How long does one cartridge last in a busy cafe?
A single-group espresso machine typically reaches the six-month mark before the 10,000-gallon capacity. High-volume ice machines can exhaust it sooner, and a drop in ice output or flow is the usual signal to change it.

Do you deliver outside Muscat?
Yes. We ship to Sohar, Salalah, Nizwa, Duqm and the interior. Contact us for delivery timing to your location.
